All these genes have been classified into eight subfamilies on the bases of their phylogenetic analysis and conserved domain. Maximum members of LEA encoding genes were found to be a part of the LEA_2 gene family. The analysis of physicochemical properties of LEAs was also conducted. LEA encoding genes have been found to be located in all chromosomes (8 chr) of chickpea and identified as involved in response to stimulus, biological processes, molecular functions and cellular components based upon gene ontology analysis. Gene expression analysis of randomly selected 8 LEA encoding genes has been carried out during different seed developmental stages which revealed the higher expression of LEA encoding genes during later stage of seed development in chickpea and proved their potential role in desiccation process during seed maturation. During seed germination, expression analysis of LEA encoding genes was found to be higher during the initial stages of seed germination. In conclusion, this work highlights the genome wide identification and characterization of LEA encoding genes in chickpea and proposed potential roles during seed developmental processes.

Given the significance of cereal crops as a primary source of food for the global population, the utilization of contemporary genome editing techniques like CRISPR/Cas9 is timely and crucial. CRISPR/Cas technology has enabled targeted genomic modifications, revolutionizing genetic research and exploration. Application of gene editing through CRISPR/Cas9 in enhancing sorghum is particularly vital given the current ecological, environmental, and agricultural challenges exacerbated by climate change. As sorghum is one of the main staple foods of our region and known to be a resilient crop with high potential to overcome the above challenges, application of genome editing technology will enhance investigation of gene functionality. CRISPR/Cas9 enables the improvement of desirable sorghum traits, including nutritional value, yield, resistance to pests and diseases, and tolerance to various abiotic stresses. Furthermore, CRISPR/Cas9 has the potential to perform intricate editing and reshape the existing elite sorghum varieties, and introduce new genetic variations. However, current research primarily focuses on improving the efficacy of CRISPR/Cas9 system in successfully editing endogenous sorghum genes, making it a feasible and successful undertaking in sorghum improvement. Recent advancements and developments in CRISPR/Cas9 techniques have further empowered researchers to modify additional genes in sorghum with greater efficiency. Successful application and advancement of CRISPR techniques in sorghum will not only aid in gene discovery, the creation of novel traits that regulate gene expression, and functional genomics, but also in facilitating site-specific integration events. The purpose of this review is, therefore, to elucidate the current advances in sorghum genome editing and highlight its potential in addressing food security issues. It also assesses the efficiency of CRISPR-mediated improvement and its long-term effects on crop improvement and host resistance against parasites, including tissue-specific activity and the ability to induce resistance. This review ends by emphasizing the challenges and opportunities of CRISPR technology in combating parasitic plants, and proposing directions for future research to safeguard global agricultural productivity.</p></div>","PeriodicalId":38041,"journal":{"name":"Plant Gene","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2024-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141840843","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}

Morphological and molecular markers have been proven to be potential tools for the evaluation of genetic diversity, crop genetic improvement, and conservation of plant genetic resources. In the current study, morphological descriptors, RAPD, and SCoT markers were used to determine genetic diversity among 28 <em>M. oleifera</em> accessions. Significant morphological variations were noted for several economic traits across the accessions studied. Four primary clusters were visible on the dendrogram based on phenotypic markers, indicating clustering of accession from a shared geographical habitat. No correlation was estimated between morphological traits, indicating an environmental influence. Three RAPD and seven SCoT primer sets produced 37 and 46 markers, with 53.2 and 71.3% polymorphisms, respectively. Based on genotypic data and the UPGMA approach, all 28 accessions were separated into two major clusters in the phylogenetic tree, irrespective of any geographical areas.

Hence, the aim of this study was to identify and analyze fruit development transcriptomic changes on six commercial durian varieties (D24, D99, D160, D168, D197, and D200). The transcriptome analysis via RNA-seq assays generated 67 to 234 million raw reads, which are assembled into 49,601 genes with protein coding genes as the largest gene biotype, with a total of 35,832 genes (72.2%). All genes were annotated against Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG). GO analysis revealed genes were highly linked to biological process, cellular components and molecular function, with the highest representation in cell wall, while the most common pathways identified by KEGG were carotenoid biosynthesis, fatty acid biosynthesis, starch and sucrose metabolism, phenylpropanoid biosynthesis and galactose metabolism. Important changes were found in abscisic acid and lignin accumulation, which associated with post-harvest response and concurrent colour change. Moreover, significant increase in butyric acid, palmitoyl-CoA and different forms of sugars were associated with buttery smell, creamy texture, and sweetness respectively. Thus, mass sequence data and expression profiling provide an insight into molecular mechanisms for durian fruit developmental process.
