Stem cells residing in plant apical meristems play an important role during postembryonic development. These stem are the wellspring from which tissues and organs of emerge. The shoot meristem (SAM) governs aboveground portions a plant, while root (RAM) orchestrates subterranean system. In their sessile existence, plants inextricably bound to environment must adapt various abiotic stresses, including osmotic stress, drought, temperature fluctuations, salinity, ultraviolet radiation, exposure heavy metal ions. environmental challenges exert profound effects on cells, potentially causing severe DNA damage disrupting equilibrium reactive oxygen species (ROS) Ca 2+ signaling these vital jeopardizing integrity survival. response challenges, have evolved mechanisms ensure preservation, restoration, adaptation meristematic cell niche. This enduring allows thrive habitats over extended periods. Here, we presented comprehensive overview cellular molecular intricacies surrounding initiation maintenance We also delved into employed by withstand respond stressors.

Diel changes in the environment are perceived by circadian clock which transmits temporal information throughout plant cell to synchronize daily and seasonal environmental signals with internal biological processes. Dynamic modulations of diverse levels gene regulation within impacted stress. Recent insights into control cellular processes such as alternative splicing, polyadenylation, noncoding RNAs discussed. We highlight studies on reactive oxygen species, calcium signaling, gating temperature stress responses. Finally, we briefly summarize recent work translation-specific rhythmicity cycle genes subcellular localization relocalization oscillator components. Together, this mini-review highlights these events context responses Arabidopsis.

Soil salinization, an intractable problem, is becoming increasingly serious and threatening fragile natural ecosystems even the security of human food supplies. Sorghum (Sorghum bicolor L.) one main crops growing in salinized soil. However, tolerance mechanisms sorghum to saline–alkaline soil are still ambiguous. In this study, RNA sequencing was carried out explore gene expression profiles treated with sodium bicarbonate (150 mM, pH = 8.0, for 0, 6, 12 24 h). The results show that 6045, 5122, 6804, 7978, 8080 12,899 differentially expressed genes (DEGs) were detected shoots roots after h treatments, respectively. GO, KEGG weighted co-expression analyses indicate DEGs generated by stress primarily enriched plant hormone signal transduction, MAPK signaling pathway, starch sucrose metabolism, glutathione metabolism phenylpropanoid biosynthesis. Key pathway hub (TPP1, WRKY61, YSL1 NHX7) mainly related intracellular ion transport lignin synthesis. molecular physiological regulation processes saline–alkali-tolerant shown these results, which also provide useful knowledge improving yield quality under conditions.
