Summary: BAM genes in Annona atemoya are important to starch degradation and can be divided into four groups. AaBAM3 may function in the whole fruit ripening process, while AaBAM1.2 may be important to starch degradation in other organs. Temperature and ethylene affect the expression of major AaBAM genes in Subfamily I during fruit ripening.

Summary: The study established an early model of the malting barley transcriptome, identified the period with the largest dynamic shift in gene expression during malting, and determined the expression patterns of starch degrading enzyme genes relevant to the malting and brewing industry. Large dynamic increases in gene expression occurred early in malting, with differentially expressed genes enriched for cell wall and starch hydrolases among other malting related categories.

Summary: In this study, A and B-type starches were treated with Maltogenic a-amylase (MA). The results showed that MA treatment did not affect the integrity of starch granules, but it reduced the thickness of crystalline and amorphous sheets in both modified starches. HPAEC analysis revealed that MA mainly acted on side chains in amylopectin, resulting in a decrease in viscosity. Furthermore, RVA and DSC assays demonstrated that retrogradation was retarded in both modified starches. These findings provide insights into the changes in structure and properties of MA modified starch granules and offer a novel method to retard retrogradation in starchy foods without gelatinization processing.

Summary: The development of functional foods has led to the emergence of starch-polyphenol V-type complexes, which have shown potential in reducing starch digestibility and increasing resistant starch content. However, the mechanisms and categorization of these complexes require further research. Future advancements may classify these complexes as a new type of resistant starch.

Summary: This study used two commercial alpha-amylases to improve the gel strength of cross-linked tapioca starch. The results showed that one alpha-amylase mainly attacked amorphous regions, while the other alpha-amylase hydrolyzed both amorphous regions and amorphous lamella of crystalline regions. The analysis of pasting and gelling properties indicated that the alpha-amylase increased the storage modulus of cross-linked starch gels, while the other alpha-amylase formed a solid gel.

Summary: In this study, porous starches were prepared from native corn starch with different degrees of hydrolysis using a specific raw starch-digesting amylase. The high hydrolysis degree resulted in lower relative crystallinity and promoted interactions involving disordered chains, leading to the formation of sub-microcrystalline structures. Additionally, the highly hydrolyzed starch showed lower hydrolysis rates and higher resistant starch content.

Summary: Tropospheric ozone has significant effects on the remobilization and allocation efficiency of aboveground biomass and nutrients in cereal crops. Long-term ozone exposure increases straw C:N ratio and affects grain C:N ratio. Grain N concentrations increase significantly under ozone stress, but N yield declines due to grain yield losses. Various indicators of N use efficiency are reduced, indicating reduced N absorption from soil and allocation from vegetative to reproductive organs. Straw C:N ratio is not suitable for predicting wheat productivity. Nitrogen harvest index (NHI) is not affected by ozone stress, but the relationship between harvest index (HI) and NHI is changed by elevated ozone concentration.

Summary: This study aimed to investigate the physiological response of broccoli leaves to abiotic stresses such as salinity and boron toxicity/deficiency. The results showed that the combined stress of salinity and boron deficiency resulted in a significant reduction in plant biomass, and the adaptation mechanisms were associated with water and boron concentration in the leaves. The expression patterns of PIP aquaporins varied among the different stress treatments, and their presence in the plasma membrane and interaction with the lipid environment played potential regulatory roles in facilitating salinity-boron stress adaptation mechanisms.

Summary: Plants activate a sophisticated signaling cascade in response to pests and pathogens, with lipids playing a crucial role in mediating these defense responses. Different types of lipids are involved in cell signaling during plant-pathogen interaction and each lipid has specific relevance and contributes to specific signaling cascades. Lipid biosynthetic enzymes, including phospholipases, are involved in the production of defense signaling molecules. Lipids participate in stress signaling by mediating signal transduction, acting as precursors for bioactive molecules, regulating ROS formation, and interacting with phytohormones.

Summary: Plants have evolved a mechanism called 'stress memory' to survive in various environmental stresses. This study reveals the physiological, biochemical, and molecular mechanisms underlying drought stress memory formation in cotton, highlighting the role of histone modification H3K4me3 in regulating transcriptional memory. It also investigates the intergenerational inheritance of drought stress memory in cotton, providing theoretical guidance for cotton breeding.
