The main obstacle for sustained supply of agricultural products and feeding the globe in coming years is abiotic stress. Plants typically shorten their developmental processes under stress, which eventually has a negative impact on production. A key phytohormone that plays crucial role combating stress abscisic acid (ABA). ABA significant absorbing signals guiding subsequent responses. For an outcome, plants must consistently control levels response to shifting environmental factors. In addition helping adapt diverse conditions like drought, salt, temperature also controls number physiological functions, including stomatal opening protein synthesis. variety defense mechanisms against are regulated by ABA, produced various organs stressful situations. These include controlling aperture expression genes confer resistance stresses. Based current available literatures, this review provides insights ABA's function context stresses, with focus its synthesis, signaling pathways, regulatory root architecture, over movement, intricate interactions other phytohormones.

Mechanism of ABA in Plants Exposed to Cold Stress

Agronomy, Год журнала: 2025, Номер 15(2), С. 403 - 403

Опубликована: Фев. 4, 2025

Abscisic acid (ABA) is a natural hormone produced in plants, which plays an important role plant growth and development response to adversity. Increasing research indicates that ABA involved cold stress enhances the tolerance of plants through various pathways. Therefore, roles, regulator mechanisms pathways are summarized. In this paper, we first discuss mechanism damage plants. Second, review roles enhancing tolerance, including interactions between endogenous exogenous ABA, other substances, specific genes transcription factors, phosphorylation. On whole, involvement plant’s constitutes complex multi-dimensional system. interacts with hormones, enzymes, so on, establish regulatory network resistance injury. Finally, also provide some perspectives for future on hope paper can lessons adversity stress.

Joint transcriptomic and metabolomic analysis provides new insights into drought resistance in watermelon (Citrullus lanatus)

Frontiers in Plant Science, Год журнала: 2024, Номер 15

Introduction Watermelon is an annual vine of the family Cucurbitaceae . plants produce a fruit that people love and have important nutritional economic value. With global warming deterioration ecological environment, abiotic stresses, including drought, become factors impact yield quality watermelon plants. Previous research on drought resistance has included analyzing homologous genes based known drought-responsive pathways in other species. Methods However, identifying key involved through high-throughput omics methods particularly important. In this study, RNA-seq metabolomic analysis were performed at five time points (0 h, 1 6 12 h 24 h) before after stress. Results Transcriptomic revealed 7829 differentially expressed (DEGs) points. The DEGs grouped into clusters using k-means clustering algorithm. functional category for each cluster was annotated Kyoto Encyclopedia Genes Genomes (KEGG) database; different associated with A total 949 metabolites divided 10 categories, lipids lipid-like molecules accounting most metabolites. Differential expression 22 regulated (DRMs) among Through joint metabolome data, 6-h period identified as critical resistance, starch sucrose metabolism, plant hormone signal transduction photosynthesis regulatory resistance. addition, 15 candidate combined weighted correlation network (WGCNA). Four these encode transcription factors, bHLH ( Cla97C03G068160 ), MYB Cla97C01G002440 HSP Cla97C02G033390 ) GRF Cla97C02G042620 one gene ABA pathway, SnRK2-4 Cla97C10G186750 GP-2 Cla97C05G105810 which metabolism pathway. Discussion summary, our study provides theoretical basis elucidating molecular mechanisms underlying new genetic resources crop.

Genome-Wide Identification and Characterization of HSP70 Gene Family in Tausch’s Goatgrass (Aegilops tauschii)

Genes, Год журнала: 2024, Номер 16(1), С. 19 - 19

Опубликована: Дек. 26, 2024

Aegilops tauschii, a winter annual grass weed native to Eastern Europe and Western Asia, has become widespread invasive species in the wheat-growing regions of China due its high environmental adaptability. This study aims explore molecular mechanisms underlying stress resistance Tausch's goatgrass, focusing on HSP70 gene family. A genome-wide analysis was conducted identify characterize family A. tauschii. Afterward, their physicochemical properties, phylogenetic relationships, structures, chromosomal distributions were analyzed. Additionally, cis-acting regulatory elements predicted understand potential role resistance. total 19 identified genes classified into four subfamilies distributed across all chromosomes. The syntenic revealed extensive homology between goatgrass wheat genes. Segmental duplication found play crucial expansion prediction suggested that these are involved various conditions. provides comprehensive overview offering insights application understanding behavior improving resilience. Further research is needed validate functional roles adaptation.

Plant defense polypeptides play a crucial role in providing plants with constitutive immunity against various biotic and abiotic stressors. In this study, we explored complex of proteins from wheatgrass (Elytrigia elongata) spikelets to estimate their the plant’s tolerance environmental factors. The current research shows that vitro protein extracts E. elongata possess antifungal activity certain Fusarium species, which are specific cereal pathogens, at concentrations 1–2 mg/mL. reproduced these activities using 4 mg/mL extract artificial fungal infection experiments on wheat grain (Triticum aestivum) under controlled laboratory conditions. Furthermore, tested demonstrated protective effect Saccharomyces cerevisiae exposed hyper-salinity stress concentration 2 A combined scheme fractionation structural identification was applied for estimation diversity polypeptides. Defensins, lipid-transfer proteins, hydrolase inhibitors (cereal bifunctional trypsin/alpha-amylase Bowman–Birk trypsin inhibitor), high-molecular-weight disease resistance were isolated extract. Thus, appear be reservoir Our findings contribute deeper understanding plant peptides involvement adaptation factors, they reveal regulatory ecosystem level.
