This study developed a new method (MGB-SSR) to rapidly identify genetic variations in jujube plants, allowing for more efficient breeding and classification of jujube germplasm.
Researchers studied tomato ripening in two near-isogenic lines, NIL115 and NIL080, and identified genes that improve fruit firmness and shelf life. This research could help reduce postharvest losses and improve fruit quality through assisted breeding.
The study analyzed two families of transcription factors involved in drought response and found that the wild genotype showed higher expression levels than the commercial genotype, suggesting their importance in drought tolerance. The results also suggest that commercial genotypes may have lost their ability to respond to drought.
This study obtained a high-quality genome of the apricot variety 'Xiaobaixing', which revealed specific genes associated with sweetness/bitterness traits and amygdalin synthesis. This information can help identify and regulate the quality of apricot kernels.
Scientists identified and characterized 124 HMGR genes in 36 plant species, finding more in vascular plants. Two genes, LerHMGR1 and LerHMGR2, were highly expressed during shikonin biosynthesis. This provides insight into the evolutionary properties and function of the HMGR family in plants, and can be used to improve the production of secondary metabolites.
Sucrose synthases (SUS) were studied in sweet potato and its relatives. They play a crucial role in sucrose metabolism, carbon allocation, and energy conservation in nonphotosynthetic cells. The study identified nine SUS genes in sweet potato, which were divided into three subgroups based on their relationships. The genes underwent duplications during evolution and were highly expressed in storage root development and starch biosynthesis. They also responded to drought and salt stress and could participate in hormone crosstalk. This research provides insights for improving yield, starch content, and abiotic stress tolerance in sweet potatoes.
The AT-hook motif nuclear localized (HAM) gene family in plants plays a crucial role in growth and stress tolerance. This study identified and analyzed 42 HAM family genes in plants, revealing their location in the nucleus, their involvement in stress responses and hormone regulation, and their varied expression patterns. The study also predicted interactions between HAM genes and proteins under different stress conditions.
This research studied gene expression during grain germination in barley, wheat, and rye. The study found differences in gene expression levels specific to each species, providing new information for understanding the germination process in cereals.
