To explore the molecular mechanism of response nitrogen (N) addition conditions in S. canadensis, physiology and transcriptome analysis were performed with samples cultured by natural three N level Comparative detected many differentially expressed genes (DEGs), including function growth development, photosynthesis, antioxidant, sugar metabolism secondary pathways. Most encoding proteins involved growth, circadian rhythm photosynthesis upregulated. Furthermore, metabolism-related specifically among different groups; for example, most DEGs related phenol flavonoid synthesis downregulated N-level environment. diterpenoid monoterpenoid biosynthesis In addition, physiological responses, such as antioxidant enzyme activities chlorophyll soluble contents, elevated environment, which was consistent gene expression levels each group.

Abstract Plants evolve stress‐specific responses that sense changes in their external environmental conditions and develop various mechanisms for acclimatization survival. Calcium (Ca 2+ ) is an essential stress‐sensing secondary messenger plants. Ca sensors, including calcium‐dependent protein kinases (CDPKs), calmodulins (CaMs), CaM‐like proteins (CMLs), calcineurin B‐like (CBLs), are involved jasmonates (JAs) signalling biosynthesis. Moreover, JAs phospholipid‐derived phytohormones control plant response to abiotic stresses. The pathway affects hormone–receptor gene transcription by binding the basic helix–loop–helix (bHLH) factor. MYC2 acts as a master regulator of module assimilated through genes. sensor CML regulates distinct mechanism mediating during This review highlights pivotal role sensors biosynthesis ‐mediated stresses

Oil palm (Elaeis guineensis) is the highest oil-yielding commercially grown perennial tree. germplasm conservation and in vitro clonal propagation strengthened world’s efforts to ensure future food security. Cryopreservation provides long-term storage for germplasm. The of plant material at cryogenic temperatures (−196 °C) following dehydration causes cryoinjury. cryotolerance mechanism has rarely been studied oil zygotic embryos (ZE) embryogenic calli (EC). A simple effective cryopreservation method was established ZE.
