Summary: We identified a sweet potato yield-related gene, IbAPS, and found that it positively affects AGP activity, starch biosynthesis, leaf development, chlorophyll metabolism, and photosynthesis, leading to increased vegetative biomass and storage root yield. IbAPS also affects other storage root development-associated events and plays a crucial role in carbohydrate metabolism, plant growth, and storage root yield.

Summary: The study investigated carbon flow in three high-yielding rice cultivars and found that in 'Momiroman', newly fixed carbon assimilates were stored as hexose instead of being converted to starch. Additionally, lower activity of ADP-glucose pyrophosphorylase and lower expression of AGPS2b in 'Momiroman' grains may be the main reasons for slower starch synthesis and lower sink activity in this cultivar.

Summary: Flooding caused by heavy rainfall and poor soil drainage can negatively affect plant germination and seedling establishment. Rice, however, has unique strategies, such as fast elongation of coleoptiles, to cope with flooding. Microorganisms can contribute to rice health by promoting growth and protecting against stress. A metagenomic analysis of the microbiome during rice germination under submergence revealed distinct compositions of microbiota in different rice varieties, with Arborio seeds showing the development of long coleoptiles. The isolated bacteria were found to have starch hydrolyzing and indole-related compound production abilities under hypoxia. Inoculating these bacteria into submerged rice seeds showed a genotype-dependent response. These findings highlight the importance of endophytic bacteria in promoting rice seedling establishment during flooding.

Summary: Sweet corn, with its sh2 gene, has a higher sugar content compared to field corn. This study sequenced the entire Sh2 gene among different corn inbreds, identifying SNPs and InDels that differentiated between wild and mutant alleles. The research also compared the gene sequence and diversity of sh2 in maize with related orthologues in other monocots.

Summary: This study provides a comprehensive characterization and diversity analysis of sh2 gene in maize and related orthologues in various monocots. The study identifies SNPs and InDels, develops markers to assess sh2 gene-based diversity, compares gene sequences among different inbreds, and analyzes the phylogenetic relationship between maize and other monocots. The study also reveals the conserved domains and physicochemical properties of SH2 protein and provides valuable information for further research on sweet corn breeding and improvement.

Summary: A study found that phosphorus deficiency increases seed oil content and alters fatty acid composition of Camelina seeds, but greatly reduces seed production. This suggests that achieving a high yield and quality of Camelina seed oil is closely linked to the phosphorus status of the soil.

Summary: Beta-amylases (BAMs) play a crucial role in transitory starch degradation in chloroplasts, regulating the availability of photosynthetically fixed carbon over the diel cycle in plants. The characterization of BETA-AMYLASE 9 (BAM9) in Arabidopsis revealed its conservation in plants and unique regulation of starch breakdown compared to BAM4. BAM9 activates starch degradation and responds to environmental changes, making it a valuable gene target for managing carbohydrate availability in fluctuating conditions.

Summary: Camelina is an orphan oil crop that shows potential for yield improvement through breeding and biotechnological approaches. The CYP78A genes from arabidopsis have been found to regulate seed development in camelina, with excessive expression affecting fertility while moderate expression enhances seed weight and oil content. This study demonstrates that manipulating the expression levels of CYP78A genes can be a powerful strategy for modifying plant biomass and seed traits in camelina.

Summary: This paper provides an overview of the initial steps of camelina-based production process, including plant cultivation and harvesting, seed pretreatment, and oil recovery. The characteristics of camelina plant and seed are briefly described, and the important issues of camelina seed harvesting, cleaning, drying, storing, and pretreating are discussed. The focus of the paper is on oil recovery from pretreated seed, emphasizing the traits of various recovery methods and the physicochemical properties and composition of camelina oil. The traditional, actual, and prospective uses of camelina seed, oil, meal, and straw are also briefly overviewed.

Summary: Studies on camelina performance in northern France showed that major limiting factors affecting yield and quality variations were nitrogen crop status, downy mildew, and weed biomass. Understanding these factors can help improve camelina performance through selecting resistant genotypes, managing nitrogen fertilization, and adjusting sowing dates.

Summary: Seed longevity is crucial for plant germplasm conservation, species reproduction, geographical distribution, crop yield and quality, and food safety. The decrease in seed longevity and vigor during storage directly impacts seed germination and post-germination seedling establishment. Studies have shown that the rapid catabolism of triacylglycerols, fatty acids, and sugars during seed storage is closely linked to seed longevity.

Summary: Genetic variation in seed protein composition, gene expression, and physiochemical properties were found in C. sativa and other Camelina species. Four different types of cruciferins were identified in C. sativa, each with unique functional properties. This study provides opportunities to create C. sativa cultivars with tailored seed protein profiles for specific technical applications.
