Summary: This study investigates the morphological characteristics and potential molecular mechanisms of different types of buds in dioecious Salix. It reveals the development dynamics, gene expression differences, and dynamic changes in sex determination mechanisms of flower buds and leaf buds. The study provides new insights into the molecular mechanisms of dioecious buds and their development, dormancy breaking, flowering, and sexual association.

Summary: This study aimed to identify genetic factors associated with seed oligosaccharides in chickpea and identified potential candidate genes for sugar metabolism and transport. Quantitative analysis of sugar contents in chickpea showed wide variations between different accessions. Nine candidate genes were identified, which could be utilized in breeding and genetic engineering to improve sugar profiles in legumes and other crops.

Summary: This study used the genetic diversity in Medicago truncatula to identify genes/loci regulating seed traits through a genome-wide association study, revealing a strong positive correlation between seed size and protein content, as well as multiple QTNs associated with different seed phenotypes. The findings represent valuable resources for improving legume grain production in species such as pea, common bean, and soybean.

Summary: This study evaluated the effects of three plant growth-promoting rhizobacteria on root development and subsequent plant growth of cannabis. The results showed that these rhizobacteria increased root length at the vegetative stage and flower fresh weight at harvest. The differences in plant height, node number, branch number, and leaf area between the treated plants and the control group were minimal. The specific rhizobacterium Pseudomonas sp. had the greatest impact on photosynthetic rate, harvest index, flower number, and axillary bud outgrowth rate. Future research should focus on investigating the effects of these rhizobacteria on the secondary metabolite profile of cannabis flowers at harvest.

Summary: This study identified significant SNPs for seed weight on chromosomes 2 and 16 and identified GmCYP78A57 as a candidate gene for controlling seed size in soybean. Another gene on chromosome 16 may play an important role in reducing seed size. Genomic variations of GmCYP78A57 were identified with allelic variations affecting seed weight ranging from 4.4 to 17.6 g.

Summary: In this study, GWAS identified four QTLs associated with cold tolerance at the bud burst stage in rice. Among them, one QTL overlaps with a known cold tolerance micro RNA gene. The study also revealed that OsRab11C1 is a negative regulator of cold tolerance in rice, and knocking out this gene may enhance cold tolerance in rice.

Summary: A candidate gene cytochrome b5 for the major QTL qSRMP9 for rice seed reserve mobilization was validated during seed germination using a genome-wide association study approach. The disruption of this gene in Oscyb5 mutants led to reduced seed reserve mobilization and seedling growth compared to wild-type rice. The natural variation of OsCyb5 associated with seed reserve mobilization could be useful for future rice breeding efforts.

Summary: Changes in polyamine levels play a crucial role in sex differentiation and unisexual flower development in cucumbers. The inhibition of generative organ development of the opposite sex is essential for sex differentiation. Female flowers exhibit higher levels of total polyamines, with increased cadaverine associated with female flower maturation.

Summary: Field pennycress is a new winter annual cash cover crop with high oil content and seed yield. A genome-wide association study (GWAS) was conducted to identify marker trait associations for seed size and composition related traits. The study found significant marker-trait associations and identified candidate genes that can accelerate pennycress breeding progress.

Summary: Nine candidate intervals for wheat GPC were identified through key message linkage and association mapping, leading to the discovery of 3 significant markers through large-scale association mapping based on KASP markers and F-4 breeding lines. These markers were found to significantly enhance wheat quality breeding by improving grain protein content (GPC). The study results suggest that these markers have high selective efficiency and may offer a novel route for improving wheat quality breeding.

Summary: This study found that defoliants are not effective alternatives to HC for bud dormancy-breaking, and that HC and ZS have different modes of action in inducing blueberry budbreak. The high efficacy of HC in breaking dormancy may be due to its ability to reduce ABA concentrations, and the accumulation of JA is suggested to be involved in blueberry budbreak induction.
