Summary: TaPGS1, a transcription factor belonging to the basic helix-loop-helix family, is specifically expressed during seed development in wheat. Overexpression of TaPGS1 increases grain weight and size, as well as carbohydrate and total protein levels. TaPGS1 regulates the expression of PLATZ transcription factor genes and plays a critical role in cereal grain development.

Summary: Seed development involves the coordination of embryo growth, embryo-nourishing endosperm, and maternal tissue. The endosperm is closely related to nutritional dynamics, developmental signaling, and imprinted gene expression. The diversity of endosperm in angiosperms deserves further examination.

Summary: The endosperm of wheat seeds plays a role as a nutrient reservoir during germination and responds to different abiotic stresses through modification of protein profiles. Functional classification of differentially expressed proteins (DEPs) under PEG, NaCl and submergence treatments revealed their involvement in protein, amino acid and organic acid metabolic processes, with specific metabolic pathways highlighted in each stress condition. The identification of stress-related proteins and their biased expression in different stresses suggests an active stress-responding role of endosperm beyond nutrient storage during germination.

Summary: In this study, the interactive effects of ozone, temperature, and water supply on wheat yield and grain quality were assessed. It was found that ozone, warming, and drought all decreased grain yield and average grain mass but increased grain concentration of nutrients. The results highlight the importance of considering water availability when assessing the impact of ozone on global food production.

Summary: The study suggests that SISWEET15 plays a role in mediating sucrose efflux from releasing phloem cells to fruit apoplasm and subsequent import into storage parenchyma cells during fruit development. Furthermore, SISWEET15-mediated sucrose efflux is likely required for sucrose unloading from the seed coat to the developing embryo.

Summary: Expressing a bacterial glucan synthase in wheat grains led to the accumulation of high levels of maltose, causing swelling during development and shrivelling upon maturity. Cytosolic glucan synthesized was hydrolyzed immediately to maltose, attracting excess water and stretching the seed coat before shrinking during grain maturation.

Summary: Our genome-wide analysis identified 32 Hsfs and 22 small heat shock proteins (LsHsps) in lettuce, some of which do not have orthologs in Arabidopsis, poplar, and rice. Surprisingly, LsHsp70s have three times more members than Arabidopsis and two times more than rice, mostly due to genome tandem duplication. The transcriptional analysis revealed that genes from certain families were highly responsive to UV and high intensity light stress, providing candidate genes for breeding lettuce varieties resilient to artificial light in hydroponic systems.

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.
