Abstract

Plant transcription factors (TFs), such as basic helix-loop-helix (bHLH) and AT-rich zinc-binding proteins (PLATZ), play critical roles in regulating the expression of developmental genes in cereals. We identified the bHLH protein TaPGS1 (T. aestivum Positive Regulator of Grain Size 1) specifically expressed in the seeds at 5-20 days post-anthesis in wheat. TaPGS1 was ectopically overexpressed (OE) in wheat and rice, leading to increased grain weight (up to 13.81% in wheat and 18.55% in rice lines) and grain size. Carbohydrate and total protein levels also increased. Scanning electron microscopy results indicated that the starch granules in the endosperm of TaPGS1 OE wheat and rice lines were smaller and tightly embedded in a proteinaceous matrix. Furthermore, TaPGS1 was bound directly to the E-box motif at the promoter of the PLATZ TF genes TaFl3 and OsFl3 and positively regulated their expression in wheat and rice. In rice, the OsFl3 CRISPR/Cas9 knockout lines showed reduced average thousand-grain weight, grain width, and grain length in rice. Our results reveal that TaPGS1 functions as a valuable trait-associated gene for improving cereal grain yield.

Abstract

The basic leucine zipper (bZIP) family of genes encode transcription factors that play key roles in plant growth and development. In this study, a total of 92 HvbZIP genes were identified and compared with previous studies using recently released barley genome data. Two novel genes were characterized in this study, and some misannotated and duplicated genes from previous studies have been corrected. Phylogenetic analysis results showed that 92 HvbZIP genes were classified into 10 groups and three unknown groups. The gene structure and motif distribution of the three unknown groups implied that the genes of the three groups may be functionally different. Expression profiling indicated that the HvbZIP genes exhibited different patterns of spatial and temporal expression. Using qRT-PCR, more than 10 HvbZIP genes were identified with expression patterns similar to those of starch synthase genes in barley. Yeast one-hybrid analysis revealed that two of the HvbZIP genes exhibited in vitro binding activity to the promoter of HvAGP-S. The two HvbZIP genes may be candidate genes for further study to explore the mechanism by which they regulate the synthesis of barley starch. Key words: barley, basic leucine zipper, transcription factors, gene interaction, starch synthesis.

A laide de la qRT-PCR, les auteurs ont identifie plus de 10 genes HvbZIP affichant une expression semblable a celle des genes codant pour lamidon synthase chez l'orge.

Abstract

In our previous work, a novel high-molecular-weight glutenin subunit (HMW-GS) with an extremely large molecular weight from Aegilops sharonensis was identified that may contribute to excellent wheat (Triticum aestivum) processing quality and increased dough strength, and we further generated HMW-GS homozygous lines by crossing. In this study, we crossed the HMW-GS homozygous line 66-17-52 with 'Chinese Spring' Phl mutant CS phlb to induce chromosome recombination between wheat and Ae. sharonensis. SDS-PAGE was used to identify 19 derived [F.sub.2] lines with the HMW-GSs of Ae sharonensis. The results of non-denaturing fluorescence in situ hybridization (ND-FISH) indicated that lines 6-1 and 6-7 possessed a substitution of both 5D chromosomes by a pair of 1[S.sup.sh] chromosomes. Further verification by newly developed 1[S.sup.sh]-specific chromosome markers showed that these two lines amplified the expected fragment. Thus, it was concluded that lines 6-1 and 6-7 are 1[S.sup.sh](5D) chromosome substitution lines. The 1[S.sup.sh](5D) chromosome substitution lines, possessing alien subunits with satisfactory quality-associated structural features of large repetitive domains and increased number of subunits, may have great potential in strengthening the viscosity and elasticity of dough made from wheat flour. Therefore, these substitution lines can be used for wheat quality improvement and further production of 1[S.sup.sh] translocation lines. Key words: Aegilops sharonensis, substitution line, Ph gene mutant, high-molecular-weight glutenin subunits, molecular markers. Dans leurs travaux precedents, les auteurs ont identifie une nouvelle sous-unite de glutenine de masse moleculaire elevee (HMW-GS) de tres grande masse chez l'Aegilops sharonensis, laquelle pourrait contribuer a produire un ble (Triticum aestivum) dote de meilleures proprietes pour la transformation et d'une meilleure resistance de la pate. Les auteurs ont egalement genere des lignees homozygotes HMW-GS par la voie de croisements. Dans ce travail, les auteurs ont croise la lignee homozygote 66-17-52 avec le mutant Ph1 de Chinese Spring (CS ph1b) pour produire des recombinants chromosomiques entre le ble et l'Ae. sharonensis. Des gels SDS-PAGE ont ete employes pour identifier 19 descendants [F.sub.2] porteurs de HMW-GS de l'Ae. sharonensis. Les resultats d'hybridations in situ en fluorescence en conditions non-denaturantes (ND-FISH) ont revele que les lignees 6-1 et 6-7 presentent une substitution des deux chromosomes 5D par une paire de chromosomes 1[S.sup.sh]. Des analyses additionnelles realisees au moyen de marqueurs specifiques du chromosome 1[S.sup.sh] nouvellement mis au point ont montre que les fragments attendus ont ete obtenus chez ces deux lignees. Les auteurs concluent donc que les lignees 6-1 et 6-7 sont des lignees de substitution 1[S.sup.sh](5D). Ces lignees de substitution chromosomique 1[S.sup.sh](5D) possedent des sous-unites d'origine interspecifique qui presentent des caracteristiques structurales associees a une meilleure qualite, soit la presence de grands domaines repetes et un nombre accru de sous-unites. Celles-ci permettront possiblement d'accroitre la viscosite et l'elasticite de la pate preparee a partir de farine de ble. Ainsi, ces lignees de substitution pourront servir a ameliorer la qualite du ble panifiable ainsi que pour la production de lignees de translocation 1[S.sup.sh].

Abstract

A completely developed and vigorous root system can provide a stable platform for aboveground plant organs. To identify loci controlling root traits that could be used in wheat (Triticum aestivum L.) breeding, 199 recombinant inbred lines were used to measure and analyze eight root traits. A total of 18 quantitative trait loci (QTL) located on chromosomes 1A, 2A, 2B, 2D, 4B, 4D, 6A, 7A, and 7B were identified. The phenotypic variation explained by these 18 QTL ranged from 3.27% to 11.75%, and the logarithm of odds scores ranged from 2.50 to 6.58. A comparison of physical intervals indicated several new QTL for root traits were identified. In addition, significant correlations between root and agronomic traits were detected and discussed. The results presented in this study, along with those of previous reports, suggest that chromosomes 2 and 7 likely play important roles in the growth and development of wheat roots. Keywords: Triticum aestivum L., recombinant inbred lines, root traits, quantitative trait loci, correlation.

Abstract

Stripe rust, caused by Puccinia striiformisf. sp. tritici(Pst), is a devastating disease in wheat worldwide. Discovering and characterizing new resistance genes/QTL is crucial for wheat breeding programs. In this study, we fine-mapped and characterized a stripe rust resistance gene, YRAYH, on chromosome arm 5BL in the Chinese wheat landrace Anyuehong (AYH). Evaluations of stripe rust response to prevalent Chinese Pstraces in near-isogenic lines derived from a cross of Anyuehong and Taichung 29 showed that YrAYHconferred a high level of resistance at all growth stages. Fine mapping using a large segregating population of 9748 plants, narrowed the YRAYHlocus to a 3.7 Mb interval on chromosome arm 5BL that included 61 annotated genes. Transcriptome analysis of two NIL pairs identified 64 upregulated differentially expressed genes (DEGs) in the resistant NILs (NILs-R). Annotations indicated that many of these genes have roles in plant disease resistance pathways. Through a combined approach of fine-mapping and transcriptome sequencing, we identified a serine/threonine-protein kinase SRPK as a candidate gene underlying YrAYH. A unique 25 bp insertion was identified in the NILs-R compared to the NILs-S and previously published wheat genomes. An InDel marker was developed and co-segregated with YrAYH. Agronomic trait evaluation of the NILs suggested that YrAYHnot only reduces the impact of stripe rust but was also associated with a gene that increases plant height and spike length.
