The current study attempts to identify significant markers linked to drought and heat tolerance and assess genomic prediction. A genome-wide association study was conducted using the 10 K wheat SNP markers for grain yield and related traits of 246 spring bread wheat genotypes from ICARDA. Traits including grain yield (GY), days to heading (DHE), days to maturity (DMA), plant height (PLH), and thousand kernel weight (TKW), were evaluated across six different locations, spanning two years 2015–2016 and 2016–2017, as per variance analysis. Grain yield and related-traits showed a considerable variation among genotypes. Moreover, GWAS using a mixed linear model (MLM), revealed 65 marker-trait associations (MTAs) across the six environments on 16 chromosomes. With an average r<sup>2</sup> value of 0.26, Genome D has the highest linkage, followed by Genomes B and A with r<sup>2</sup> values of 0.22 and 0.21, respectively. GY had the highest MTA rating (35), followed by TKW (9) and 3 for each of the other agronomic traits (DHE, DMA, PLH) at Merchouch station. The marker “<em>CAP8_c1393_327</em>” was the most significant associated marker correlated with grain yield located on chromosome 3 A across Sid El Aidi station. Additionally, the SNP markers “<em>wsnp_Ra_c26091_35652620</em>” displayed extremely significant and stable MTA for TKW on chromosome 5B at Merchouch station.

It is a crucial staple food crop globally, contributing significantly to food security. However, its productivity is severely affected by various abiotic stresses, including drought, heavy metals, salinity, heat, and cold. This review concentrates on delineating the influence of different abiotic stresses on potato plants and elucidating the responses employed by potatoes to alleviate the detrimental effects of these stressors. Additionally, this review focuses on regulating abiotic stress in potatoes through signalling molecules and their intricate interplay with phytohormones. Phytohormones such as salicylic acid (SA), abscisic acid (ABA), ethylene and jasmonic acid (JA) interact with signalling molecules, forming a complex regulatory network. This network adjusts stomatal closure, osmotic management, antioxidant defenses, and growth regulation, allowing precise abiotic stress responses. Furthermore, the review describes the role of other signalling molecules such as reactive oxygen species (ROS), calcium ions (Ca<sup>2+</sup>), nitric oxide (NO), as key mediators in the plant's stress response. Understanding the molecular mechanisms underlying abiotic stress tolerance in potato is essential for developing resilient cultivars and sustainable agricultural practices. Hence, this review also comprehensively summarizes recent research findings on the molecular mechanism involved in abiotic stress tolerance in potato plants. The information provided in this review article can be useful in developing sustainable strategies to improve abiotic stress resilience in potato cultivation.</p></div>","PeriodicalId":38041,"journal":{"name":"Plant Gene","volume":"38 ","pages":"Article 100456"},"PeriodicalIF":0.0,"publicationDate":"2024-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140878448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to these stresses, plants need to possess some memory and currently there is need to correlate ecological constraints and importance of stress memory. Stress priming deals with the plant's capacity to memorize stress onslaught and adapt to recurring stress. Oxidative stress is one such abiotic stress which disturbs the cell homeostasis and redox balance inside the cell which is thereby countered by plant's antioxidant machinery. Thus, plants need to have some kind of memory to encounter future oxidative stress. Redoxins such as glutaredoxin (GRX), thioredoxin (TRX), peroxiredoxin (PRX), nucleoredoxin (NRX) <em>etc.</em> are enzymatic antioxidants which plays vital role in the plant growth and development. NRXs have been lesser characterized in plants as per existing literature and scientometric analysis in present work sheds light on the importance of plant NRXs. Nucleoredoxin, possessing antioxidant properties and the ability to scavenge ROS, may play a crucial role in molecular priming mechanisms. The citation network analysis using VOSviewer server also showed the importance of current research and relation of NRXs with terms like ROS, gene expression regulation, plant gene, phytohormones and plant immunity. Later the <em>Cicer arietinum</em> NRX sequence was bioinformatically characterized using several tools for better understanding.
