- Abstract
The timing of floral budbreak in apple has a significant effect on fruit production and quality. Budbreak occurs as a result of a complex molecular mechanism that relies on accurate integration of external environmental cues, principally temperature. In the pursuit of understanding this mechanism, especially with respect to aiding adaptation to climate change, a QTL at the top of linkage group (LG) 9 has been identified by many studies on budbreak, but the genes underlying it remain elusive. Here, together with a dessert apple core collection of 239 cultivars, we used a targeted capture sequencing approach to increase SNP resolution in apple orthologues of known or suspected A. thaliana flowering time-related genes, as well as approximately 200 genes within the LG9 QTL interval. This increased the 275 223 SNP Axiom® Apple 480 K array dataset by an additional 40 857 markers. Robust GWAS analyses identified MdPRX10, a peroxidase superfamily gene, as a strong candidate that demonstrated a dormancy-related expression pattern and down-regulation in response to chilling. In-silico analyses also predicted the residue change resulting from the SNP allele associated with late budbreak could alter protein conformation and likely function. Late budbreak cultivars homozygous for this SNP allele also showed significantly up-regulated expression of C-REPEAT BINDING FACTOR (CBF) genes, which are involved in cold tolerance and perception, compared to reference cultivars, such as Gala. Taken together, these results indicate a role for MdPRX10 in budbreak, potentially via redox-mediated signaling and CBF gene regulation. Moving forward, this provides a focus for developing our understanding of the effects of temperature on flowering time and how redox processes may influence integration of external cues in dormancy pathways.

[SDV.BV]Life Sciences [q-bio]/Vegetal Biology ,[SDV.BDD]Life Sciences [q-bio]/Development Biology - Abstract
International audience; Dormancy is an essential developmental program that allows tree adaptation to low temperatures by inducing a bud resting state until the end of the winter. After a prolonged cold period, buds reactivate growth in response to the warm temperatures of the spring. In many Rosaceae species, it is believed that a group of genes encoding MADS-box transcription factors controls dormancy cycle. These genes are similar to SHORT VEGETATIVE PHASE (SVP) from Arabidopsis thaliana and often referred as DORMANCY-ASSOCIATED MADS-BOX (DAM) genes. Although their potential role in tree phenology, the precise function and the mode of action of SVP-like genes during the dormancy cycle are still unknown. By making use of apple tree (Malus x domestica) as a model, we have investigated the function of rosaceous SVP-like genes. We found that most of them show patterns of expression that correlate with particular phases of the dormancy cycle. However, MdSVPa, a MADS-box gene that represses budbreak when it is overexpressed in apple, was ectopically expressed during the whole cycle. We also identified several potential complexes formed by apple MADS-box proteins and interestingly, only complexes containing MdSVPa were able to bind a DNA probe carrying two CArG boxes. In the light of these results, we hypothesized that MdSVPa is an essential component of the transcriptional complexes that regulate dormancy cycle. To unravel the roles of these complexes, we have made use of DNA Affinity Purification followed by massive parallel sequencing (DAP-seq). Our DAP-seq analyses showed that MdSVPa-containing complexes bind to gene targets involved in biological processes that could affect dormancy cycle, such as hormone signaling, cell wall and lignin modifications, sugar transport, cell cycle and flower development, among others. These results allow us to build a tentative model describing distinct roles of MADS-box complexes during the dormancy cycle in apple tree.

Winter dormancy is an adaptative mechanism that temperate and boreal trees have developed to protect their meristems against low temperatures. In apple trees (Malus domestica), cold temperatures induce bud dormancy at the end of summer/beginning of the fall. Apple buds stay dormant during winter until they are exposed to a period of cold, after which they can resume growth (budbreak) and initiate flowering in response to warmer temperatures in spring. It is well-known that small RNAs modulate temperature responses in many plant species, but however, how small RNAs are involved in genetic networks of temperature-mediated dormancy control in fruit tree species remains unclear. Here, we have made use of a recently developed ARGONAUTE (AGO)-purification technique to isolate small RNAs from apple buds. A small RNA-seq experiment resulted in the identification of 17 micro RNAs (miRNAs) that change their pattern of expression in apple buds during dormancy. Furthermore, the functional analysis of their predicted target genes suggests a main role of the 17 miRNAs in phenylpropanoid biosynthesis, gene regulation, plant development and growth, and response to stimulus. Finally, we studied the conservation of the Arabidopsis thaliana regulatory miR159-MYB module in apple in the context of the plant hormone abscisic acid homeostasis.

OLIVE ,GLOBAL warming ,FLOWERING trees ,FRUIT trees ,CULTIVARS ,PARTIAL least squares regression - Abstract
Delineating chilling and forcing periods is one of the challenging topics in understanding how temperatures drive the timing of budburst and bloom in fruit tree species. Here, we investigated this question on olive trees, using flowering data collected over six years on 331 cultivars in the worldwide collection of Marrakech, Morocco. Using a Partial Least Squares approach on a long-term phenology (29 years) of 'Picholine Marocaine' cultivar, we showed that the relevance of delineating the chilling and forcing periods depends more on the variability of inter-annual temperatures than on the long-term datasets. In fact, chilling and forcing periods are similar between those delineated by using datasets of 29 years and those of only 6 years (2014–2019). We demonstrated that the variability of inter-annual temperatures is the main factor explaining this pattern. We then used the datasets of six years to assess the chill and heat requirements of 285 cultivars. We classified Mediterranean olive cultivars into four groups according to their chill requirements. Our results, using the Kriging interpolation method, indicated that flowering dates of most of these cultivars (92%) were governed by both chilling and forcing temperatures. Our investigations provided first insights to select adapted cultivars to global warming. [ABSTRACT FROM AUTHOR]

[SDV.BV]Life Sciences [q-bio]/Vegetal Biology ,[SDV.BDD]Life Sciences [q-bio]/Development Biology - Abstract
International audience; Dormancy is an adaptive mechanism that enables plants to survive unfavorable climatic conditions and allows budbreak and flowering to occur only when the conditions are permissive. This resting stage is defined by the absence of visible growth. In apple (Malus x domestica Borkh.) and many other Rosaceae species, winter bud dormancy can be divided in at least two phases: endo- and eco-dormancy. During endo-dormancy, growth repression is controlled by internal cues and it is released by long periods of cold (chilling requirement). Then, buds undergo into eco-dormancy phase and become competent to budbreak in response to warm temperatures. In the model plant species Arabidopsis thaliana, changes in ambient temperature regulate flowering time through mechanisms that involved the alternative splicing (AS) of MADS-box genes. We have hypothesized that a similar mechanism could operate to control the temperature dependent transition between endo- and eco-dormancy phases in apple tree. In order to address this question, we have performed a RNA-seq time-course experiment on buds of apple tree (cv. Golden delicious) during the dormancy cycle. RNA from time-points covering the endo- to eco-dormancy transition were sequenced and changes in gene expression and AS quantified. Our bioinformatics analyses showed that pathways related to cell wall modifications, cell cycle, chromatin silencing and hormones, among others, were affected during the transition between endo- to eco-dormancy. Moreover, we implemented a bioinformatics pipeline to identify differential alternatively spliced genes associated to this developmental transition. Here, we will show how these data are instrumental to isolate candidate genes potentially involved in dormancy-cycle control and describe mechanisms of post-transcriptional regulation involved in fruit tree development.

As all perennial plants, fruit trees must cope with multiple environmental stresses during their life. The current progressive increase in air temperature makes fruit trees particularly fragile because of their long life during which they might accumulate stresses and the long duration of the selection process to search for more adapted materials. The progressive temperature increase directly impacts the tree phenology, especially their flowering time which results from the regulation of dormancy duration. The ongoing changes endanger the flower quality and the synchronicity of flowering among varieties that is necessary for cross-pollination. Moreover, during summer, despite the irrigation of most orchards, trees must face periods of soil water deficit and/or high temperatures during which the regulation of stomatal closure may impact the tree water use efficiency. Fruit development also depends on the climatic conditions during formation and maturation whereas floral induction occurs for the next season. In this talk, we will briefly review the threats for fruit production and the physiological mechanisms possibly involved that would deserve deep investigations for provid ing a more comprehensive knowledge of fruit tree temperature perception and responses. This knowledge is indeed crucial to draw strategies for the creation of new plant material better adapted to future climatic conditions.

National audience; Dormancy is an adaptive mechanism that enables plants to survive unfavorable climatic conditions. The production of temperate fruits, such as apple (Malus x domestica Borkh.), is closely related to bud dormancy, which is triggered by exposure to cold. Therefore, the predicted impact of the ongoing climate changes will result in difficulties for apple production. The present work aims to prospect and characterize genes encoding Dormancy-Associated (DAM) and flowering-time related MADS-box transcription factors in the dormancy process of apple. On one hand, we are exploring the allelic variation present in genes involved in bud dormancy and flowering control in an apple core collection. We have developed a target capture sequencing approach and used it for genome-wide association studies (GWAS). On the other hand, we are identifying protein-protein interactions between DAM and flowering-time proteins by yeast-two-hybrid and searching for their transcriptional targets. By making use of these approaches, we have re-defined and narrow down genomic regions associated to bud dormancy. Additionally, we have identified potential transcriptional complexes containing DAM and flowering-time related proteins that act in apple bud dormancy. These studies contribute to better characterize key processes in dormancy molecular control, as well as to identify possible biotechnological resources for breeding programs.

UMR AGAP - équipe AFEF - Architecture et fonctionnement des espèces fruitières; Phenological responses to warming in temperate fruit trees have rarely been investigated in contrasting warming contexts. This framework is appropriate for highlighting varying responses that would combine chill accumulation declines and heat accumulation increases. A comprehensive overview of historical responses might clarify crucial future responses in the warmest European regions. To examine this issue, a dataset was constituted in apple from flowering dates collected for main BBCH stages in contrasting temperate regions of Western Europe and in different mild regions (Northern Morocco, Southern Brazil). Multiple change-point models were applied to series of flowering date, flowering duration and temperature, aiming to statistically analyse both flowering responses and temperature changes. Modelling of flowering date was used to understand the determinisms of warming responses. In addition, regional differences in dormancy dynamic were characterized by forcing tests. Statistical analysis provided an overview of flowering date responses at global scale, highlighting flowering advances, mainly in Europe and Morocco, but also stationary flowering date series in Brazilian and French Mediterranean regions. Modelling analysis supported the notion that flowering advances are due to heat accumulation increases, explained by marked warming during ecodormancy. Later dormancy releases due to chill declines were also supported in Europe and may explain, in long term, stationary flowering dates in the French Mediterranean region. While the flowering duration series were stationary whatever the region, the flowering duration was far longer in Moroccan and Brazilian regions compared to European. This was linked to contrasting differences in dormancy dynamic observed between these mild and temperate regions. Dormancy release was inadequate in mild due to poor chill accumulation, leading to extended flowering durations. Since later dormancy releases would already have significant impacts on flowering date in Europe, new crucial warming responses, such as extended flowering durations, could be experienced especially in Mediterranean regions in near future.

UMR AGAP - équipe AFEF - Architecture et fonctionnement des espèces fruitières; Les changements de dates de floraison du pommier dans un passé récent ont été étudiés à une échelle mondiale. Une modélisation statistique de séries de dates de floraison et de températures révèle une diversité géographique des changements de dates et du réchauffement de l’automne au printemps. Face à un contexte de réchauffement globalement croissant mais géographiquement variable, l’adaptation de la phénologie, notamment en Europe, doit ainsi être raisonnée à des niveaux régionaux dont les caractéristiques climatiques et les contours géographique sont à définir.

- Abstract
The pollen data available for the Atlantic equatorial African region indicate that during the Late Quaternary, major climate changes occurred and caused important modifications in tropical lowland rain-forest in terms of composition and distribution (Maley 1991; Elenga et al. 1991; 1994; Farrera et al. 1999; Vincens et al. 1999). Nevertheless, despite a wealth of proxy evidence from various disciplines, there are very few terrestrial sites dated continuously since the Last Glacial Maximum (LGM) to the Late Holocene in this area (e.g., Lanfranchi and Schwartz (1990), Servant and Servant-Vildary (2000)). The oldest radiocarbon-dated sites are from Lake Barombi Mbo in Cameroon (Brenac 1988; Maley 1991; Maley and Brenac 1998a) and the Ngamakala Pond in the Congo (Elenga et al. 1994), although most Holocene sequences from this area start during the mid-Holocene (Vincens et al. 1999). This paper reviews the results available for some key sites, allowing regional correlations for major Late Quaternary periods.We have focused on the vegetation changes and the climate related to these changes. Numerous radiocarbon dates allowprecise palaeoenvironmental reconstructions, especially since the mid-Holocene to be made. In this paper all 14C dates are uncalibrated. [ABSTRACT FROM AUTHOR]
