Abstract Complete and accurate reference genomes annotations provide fundamental resources for functional genomics crop breeding. Here we report a de novo assembly annotation of pea cultivar ZW6 with contig N50 8.98 Mb, which features 243-fold increase in length evident improvements the continuity quality sequence complex repeat regions compared existing one. Genome diversity 118 cultivated wild demonstrated that Pisum abyssinicum is separate species different from P. fulvum sativum within . Quantitative trait locus analyses uncovered two known Mendel’s genes related to stem ( Le/le ) seed shape R/r as well some candidate pod form studied by Mendel. A pan-genome 116 accessions was constructed, pan-genes preferred showed distinct enrichment, indicating potential value them breeding future.

Natural allelic variation of GmST05 controlling seed size and quality in soybean

Plant Biotechnology Journal, Год журнала: 2022, Номер 20(9), С. 1807 - 1818

Опубликована: Июнь 1, 2022

Seed size is one of the most important agronomic traits determining yield crops. Cloning key genes controlling seed and pyramiding their elite alleles will facilitate improvement. To date, few have been identified in soybean, a major crop that provides half plant oil quarter protein globally. Here, through genome-wide association study over 1800 soybean accessions, we determined natural allelic variation at GmST05 (Seed Thickness 05) predominantly controlled thickness germplasm. Further analyses suggested two haplotypes differed significantly transcriptional level. Transgenic experiments demonstrated positively regulated influenced contents, possibly by regulating transcription GmSWEET10a. Population genetic diversity analysis variations were selected during geographical differentiation but not fixed. In summary, determines levels influences quality making it an gene resource for molecular breeding.

Ethylene Signaling in Regulating Plant Growth, Development, and Stress Responses

Plants, Год журнала: 2025, Номер 14(3), С. 309 - 309

Опубликована: Янв. 21, 2025

Ethylene is a gaseous plant hormone that plays crucial role in coordinating various physiological processes plants. It acts as key mediator, integrating both endogenous developmental cues and external environmental signals to regulate wide range of functions, including growth, fruit ripening, leaf abscission, responses stress. The signaling pathway initiated when ethylene binds its receptor. After decades research, the components have been identified characterized. Although molecular mechanisms sensing signal transduction studied extensively, new area research how respiration epigenetic modifications influence response. Here, we summarize progress recent years review function importance growth stress responses. In addition, also describe current understanding Together, our sheds light on ethylene.

Multi-omics revolution to promote plant breeding efficiency

Frontiers in Plant Science, Год журнала: 2022, Номер 13

Опубликована: Дек. 8, 2022

Crop production is the primary goal of agricultural activities, which always taken into consideration. However, global systems are coming under increasing pressure from rising food demand rapidly growing world population and changing climate. To address these issues, improving high-yield climate-resilient related-traits in crop breeding an effective strategy. In recent years, advances omics techniques, including genomics, transcriptomics, proteomics, metabolomics, paved way for accelerating plant/crop to cope with climate enhance production. Optimized phenotypic plasticity platform integration, exploited by evolving machine learning algorithms will aid development biological interpretations complex traits. The precise progressive assembly desire alleles using genome editing approaches enhanced strategies would enable future crops excel combating climates. Furthermore, plant genetic engineering ensures exclusive approach developing nutrient sufficient crops, productivity can sustainably adequately meet world's food, nutrition, energy needs. This review provides overview how integration could be select varieties desired

Soybean is an important crop grown worldwide, and drought stress seriously affects the yield quality of soybean. Therefore, it necessary to elucidate molecular mechanisms underlying soybean resistance stress. In this study, RNA-seq technology ultra-performance liquid chromatography–tandem mass spectrometry were used analyze transcriptome metabolome changes in leaves at seedling stage under The results showed that there 4790 3483 DEGs (differentially expressed genes) 156 124 DAMs metabolites), respectively, HN65CK vs. HN65S0 HN44CK HN44S0 comparison groups. Comprehensive analysis transcriptomic metabolomic data reveals metabolic regulation response Some candidate genes such as LOC100802571, LOC100814585, LOC100777350 LOC100787920, LOC100800547, LOC100785313 different expression trends between two cultivars, which may cause differences resistance. Secondly, a large number flavonoids identified, Monohydroxy-trimethoxyflavone-O-(6″-malonyl)glucoside was upregulated varieties. Finally, several key metabolites involved isoflavone biosynthesis TCA cycle suggesting these pathways play roles drought. Our study deepens understanding provides references for breeding.

A nitrogen fixing symbiosis-specific pathway required for legume flowering

Science Advances, Год журнала: 2023, Номер 9(2)

Опубликована: Янв. 13, 2023

Symbiotic nitrogen fixation boosts legume growth and production in nitrogen-poor soils. It has long been assumed that fixed increases reproductive success, but until now, the regulatory mechanism was unknown. Here, we report a symbiotic flowering pathway couples nutrient signals to induction legumes. We show microRNA–microRNA172c (miR172c) systemically synergistically convey nutritional cues from roots leaves promote soybean ( Glycine max ) flowering. The combinations of miR172c local elicited by development activate florigen-encoding FLOWERING LOCUS T FT homologs GmFT2a/5a repressing TARGET OF EAT1-like 4a GmTOE4a ). Thus, FTs trigger development, which allows legumes survive reproduce under low-nitrogen conditions.

As a leading oilseed crop that supplies plant oil and protein for daily human life, increasing yield improving nutritional quality (high or protein) are the top two fundamental goals of soybean breeding. Seed size is one most critical factors determining yield. size, contents complex quantitative traits governed by genetic environmental during seed development. The composition quantity storage reserves directly affect size. In general, make up almost 60% total seed. Therefore, soybean's oil, content highly correlated agronomical traits. Increasing helps increase probably improves quality. Similarly, rising will likely Due to importance these three in breeding, extensive studies have been conducted on their underlying trait locus (QTLs) genes dissection molecular regulatory pathways. This review summarized progress functional genome controlling recent decades, presented challenges prospects developing high-yield cultivars with high content. end, we hope this be helpful improvement future breeding process.
