Alhagi camelorum, a desert shrub known for its impressive drought tolerance, exhibits notable resilience under arid conditions. However, the underlying mechanisms driving resistance remain largely unexplored. This study aims to investigate these by exposing A. camelorum osmotic stress using varying polyethylene glycol (PEG) concentrations (1%, 5%, 10%) in controlled laboratory setting. Growth analysis revealed significant inhibition and phenotypic changes with increasing PEG levels. Transcriptomic analysis, including differentially expressed gene identification, GO enrichment hierarchical cluster of genes roots shoots, identified key pathways associated adaptation, such as ABA-activated signaling, cell wall biogenesis, photosynthesis, secondary metabolite biosynthesis. Notably, some involved exhibited tissue-specific expression patterns showed concentration-dependent regulation. Key findings include dose-dependent (R2 > 0.8) upregulation proline-rich protein (Asp01G030840) BURP domain-containing (Asp02G039780), well critical biogenesis (encoding Pectinesterase inhibitor Fasciclin-like arabinogalactan protein), biosynthesis enzymes terpenoid flavonoid biosynthesis). The regulation is likely influenced phytohormones ABA other stress-related hormones, along transcription factors like ABI4, TALE, MYB61, GRAS, ERF. These insights lay groundwork further research into functional roles genes, their regulatory networks, potential applications enhancing plants agricultural crops.

In plants, SPL is a distinct family of transcription factors. Its protein structure possesses highly conserved SBP domain comprising two zinc finger structures and nuclear localization regions, microRNAs (miR156) control the transcriptional expression majority genes. SPLs are key TFs in regulating organ morphogenesis, phase transition/floral induction, yield-related traits agronomic horticultural crops. These biomolecules have been functionally characterized for their role augmenting plant responses to abiotic biotic stresses. Present research gaps viewpoints addressed herein. Using these extensive data, researchers can more comprehensively understand how genes modulate features different ways.

Piriformospora/Serendipita indica has been frequently proved to play a crucial role in enhancing plant adaptation environmental stresses. However, its influence on blueberry (Vaccinium corymbosum) drought tolerance not yet studied. Here, we reported that P. colonization can significantly enhance the of blueberry. Physio-biochemical parameter determination results showed that, compared non-colonized controls (CK), indica-colonized (PI) plants exhibited higher leaf chlorophyll and carotenoids contents, photosynthetic capacity, biomass root antioxidant enzyme activities (superoxide dismutase catalase), while also exhibiting lower malondialdehyde content under stress (DS). To explore underlying mechanism, comparative transcriptome analysis well-watered (WW) DS-treated CK PI was conducted. In total, identified 14,587 differentially expressed genes (DEGs) across CK-WW vs. CK-DS, PI-WW PI-DS, CK-DS PI-DS comparisons. Under DS, stress-, metabolism- regulation-related DEGs were overwhelmingly upregulated PI, being downregulated CK. Weighted gene co-expression network categorized into four modules. Of them, MEblack module correlated with group, enriched cell wall macromolecule catabolic process, carbohydrate metabolic phenylpropanoid biosynthesis, so on. Several defense-related genes, including thaumatin family proteins, as hub this module. MEblue at highest level followed by PI-DS. Hub included DEG-encoding lipid transfer protein, abscisic ripening This study demonstrates enhances ability mediating expression related stress, secondary metabolism, metabolism.
