Abstract

Wild tomato species represent a rich gene pool for numerous desirable traits lost during domestication. Here, we exploited an introgression population representing wild desert-adapted species and a domesticated cultivar to establish the genetic basis of gene expression and chemical variation accompanying the transfer of wild-species-associated fruit traits. Transcriptome and metabolome analysis of 580 lines coupled to pathogen sensitivity assays resulted in the identification of genomic loci associated with levels of hundreds of transcripts and metabolites. These associations occurred in hotspots representing coordinated perturbation of metabolic pathways and ripening-related processes. Here, we identify components of the Solanum alkaloid pathway, as well as genes and metabolites involved in pathogen defense and linking fungal resistance with changes in the fruit ripening regulatory network. Our results outline a framework for understanding metabolism and pathogen resistance during tomato fruit ripening and provide insights into key fruit quality traits.

Abstract

Here, we report RNAseq data from a Solanum lycopersicum-pennellii introgression population (IL) and a backcross introgression population (BIL), to establish the genetic basis of gene expression and chemical variation accompanying transfer of wild species-associated fruit traits. Transcriptome analysis of these lines resulted in the identification of genomic loci significantly linked with levels of hundreds of transcripts and metabolites. These associations occurred in functionally coherent hotspots that represent coordinated perturbation of metabolic pathways and ripening-related processes. We demonstrated the efficacy of our approach by discovering yet undisclosed components of the renowned Solanum alkaloids pathway and moreover, showing that fruit fungal resistance is associated with changes in the ripening regulatory network.

Abstract

Summary: Steroidal glycoalkaloids (SGAs) are protective metabolites constitutively produced by Solanaceae species. Genes and enzymes generating the vast structural diversity of SGAs have been largely identified. Yet, mechanisms of hormone pathways coordinating defence (jasmonate; JA) and growth (gibberellin; GA) controlling SGAs metabolism remain unclear.We used tomato to decipher the hormonal regulation of SGAs metabolism during growth vs defence tradeoff. This was performed by genetic and biochemical characterisation of different JA and GA pathways components, coupled with in vitro experiments to elucidate the crosstalk between these hormone pathways mediating SGAs metabolism.We discovered that reduced active JA results in decreased SGA production, while low levels of GA or its receptor led to elevated SGA accumulation. We showed that MYC1 and MYC2 transcription factors mediate the JA/GA crosstalk by transcriptional activation of SGA biosynthesis and GA catabolism genes. Furthermore, MYC1 and MYC2 transcriptionally regulate the GA signalling suppressor DELLA that by itself interferes in JA‐mediated SGA control by modulating MYC activity through protein–protein interaction. Chemical and fungal pathogen treatments reinforced the concept of JA/GA crosstalk during SGA metabolism.These findings revealed the mechanism of JA/GA interplay in SGA biosynthesis to balance the cost of chemical defence with growth.

29. Auxin homeostasis in tomato and Arabidopsis under heat stress

Abstract

The steady increase in temperature causes worldwide losses in agriculture, therefore heat stress is a problem in many areas in the world. Tomatoes are a major horticultural crop worldwide. Their yields are maximized in climates with moderate temperatures, whereas high temperature exposure limits tomato flower development, fruit set, and thus productivity. Experimental evidence indicates that reduced fruit set at high temperatures results from inhibited pollen development, anther release, and pollen viability reduction correlating with altered metabolism of the plant hormone auxin. We have therefore set out to analyze the auxin metabolome and transcriptome in tomato flower and fruit organs to identify candidates for alteration of auxin homeostasis. Among the strongly differentially regulated genes, four GH3 genes encoding auxin conjugate synthetases were specifically upregulated in male flower organs and gametophyte during flower development of tomato. We cloned these for heterologous expression in Escherichia coli to determine their in vitro activities. One highly regulated gene encoding an amino acid conjugate hydrolase has also been investigated in terms of activity. Since the generation of transgenic tomato plants is more time consuming than transformation of Arabidopsis, we have created transgenic lines overexpressing IAA amino acid conjugate hydrolases and GH3 genes from different sources and started to analyze these for possible heat stress tolerant phenotypes. Results from work with these transgenic plants will be presented.

Abstract

The amount of cholesterol made by many plants is not negligible. Whereas cholesterogenesis in animals was elucidated decades ago, the plant pathway has remained enigmatic. Among other roles, cholesterol is a key precursor for thousands of bioactive plant metabolites, including the well-known Solanum steroidal glycoalkaloids. Integrating tomato transcript and protein co-expression data revealed candidate genes putatively associated with cholesterol biosynthesis. A combination of functional assays including gene silencing, examination of recombinant enzyme activity and yeast mutant complementation suggests the cholesterol pathway comprises 12 enzymes acting in 10 steps. It appears that half of the cholesterogenesis-specific enzymes evolved through gene duplication and divergence from phytosterol biosynthetic enzymes, whereas others act reciprocally in both cholesterol and phytosterol metabolism. Our findings provide a unique example of nature's capacity to exploit existing protein folds and catalytic machineries from primary metabolism to assemble a new, multi-step metabolic pathway. Finally, the engineering of a ‘high-cholesterol’ model plant underscores the future value of our gene toolbox to produce high-value steroidal compounds via synthetic biology.

35. Population structure and genetic diversity of the perennial medicinal shrub Plumbago.

Author

Panda S, Naik D, and Kamble A

Abstract

Knowledge of the natural genetic variation and structure in a species is important for developing appropriate conservation strategies. As genetic diversity analysis among and within populations of Plumbago zeylanica remains unknown, we aimed (i) to examine the patterns and levels of morphological and genetic variability within/among populations and ascertain whether these variations are dependent on geographical conditions; and (ii) to evaluate genetic differentiation and population structure within the species. A total of 130 individuals from 13 populations of P. zeylanica were collected, covering the entire distribution area of species across India. The genetic structure and variation within and among populations were evaluated using inter-simple sequence repeat (ISSR) and randomly amplified DNA polymorphism (RAPD) markers. High levels of genetic diversity and significantly high genetic differentiation were revealed by both the markers among all studied populations. High values of among-population genetic diversity were found, which accounted for 60 % of the total genetic variance. The estimators of genetic diversity were higher in northern and eastern populations than in southern and western populations indicating the possible loss of genetic diversity during the spread of this species to Southern India. Bayesian analysis, unweighted pair group method with arithmetic average cluster analysis and principal coordinates analysis all showed similar results. A significant isolation-by-distance pattern was revealed in P. zeylanica by ISSR (r = 0.413, P = 0.05) and RAPD (r = 0.279, P = 0.05) analysis. The results obtained suggest an urgent need for conservation of existing natural populations along with extensive domestication of this species for commercial purpose., (Published by Oxford University Press on behalf of the Annals of Botany Company.)
