However, it suffers yield losses due to weeds and bollworm infestation. Genetic modification of <i>G. arboreum</i> variety FBD-1 was attempted in the current study to combat insect and weedicide resistance by incorporating <i>cry1Ac, cry2A</i> and <i>cp4-EPSPS</i> genes under control of 35S promoter in two different cassettes using kanamycin and GUS as markers through <i>Agrobacterium</i>-mediated shoot apex cut method of cotton transformation. The efficiency of transformation was found to be 1.57%. Amplification of 1700 bp for <i>cry1Ac</i>, 167 bp for <i>cry2A</i> and 111 bp for <i>cp4-EPSPS</i> confirmed the presence of transgenes in cotton plants. The maximum mRNA expression of <i>cry1Ac</i> and <i>cp4-EPSPS</i> was observed in transgenic cotton line L3 while minimum in transgenic cotton line L1. The maximum protein concentrations of Cry1Ac, Cry2A and Cp4-EPSPS of 3.534 µg g^-1, 2.534 µg g^-1 and 3.58 µg-g^-1 respectively were observed for transgenic cotton line L3 as compared to control cotton line. On leaf-feed-based insect bioassay, almost 99% mortality was observed for <i>Helicoverpa armigera</i> on the transgenic cotton plant (L3). It completely survived the 1900 ml hectare^-1 glyphosate spray assay as compared to non-transgenic cotton plants. The necrotic spots appeared on the third day, leading to the complete death of control plants on the fifth day of assay.

A total number of 22,659,009 to 36,423,818 clean data were generated from mRNA-seq with 81 libraries, and the unique mapped reads were from 35,495,567 (86.81%) to 46,466,622 (88.95%).

A total of 220 miRNAs were predicted in this study, and all of them were identified as novel miRNA. The top three candidate KEGG pathways of miRNA were ribosome signaling pathway (13 miRNAs), spliceosome pathway (13 miRNAs), and plant hormone signal transduction pathways (10 miRNAs).

Recently, resveratrol-enriched rice has been produced as a novel source of resveratrol. This study aimed to investigate the major agronomic characteristics of resveratrol-enriched rice, Iksan526 (I526) and compared them with those of a nontransgenic and commercial rice variety, Dongjin (DJ). Transgene (RS) integration was confirmed using Southern blot analysis, and homologous recombination was achieved after digestion with the SacI restriction enzyme. The phenotypic traits of I526 grown in Iksan were similar to those grown in Milyang but not similar to those grown in Suwon. In Suwon, I526 had slightly earlier heading dates [i.e., number of days from sowing to heading) and shorter culm lengths. When I526 was treated with 0.4% Basta in the seedling stage, no significant difference was observed among all the agronomic traits compared with nontreated I526; particularly, the culm length, panicle length, number of panicles per hill, 1,000 grain weight of brown rice, and brown rice yield of the Basta-treated rice were similar to those of the nontreated I526, regardless of their cultivation region. The resveratrol content of I526 grown in Suwon and Milyang was increased by 18% and 37%, respectively, than that of I526 grown in the Iksan area. Therefore, DJ and I526 are not significantly different in terms of major agronomic traits depending on variety/year and variety/cultivation region.

Therefore, it is a prime need to grow rapeseed cultivars, which can withstand numerous abiotic stresses. To understand the various molecular and cellular mechanisms underlying the abiotic stress tolerance and improvement in rapeseed, omics approaches have been extensively employed in recent years. This review summarized the recent advancement in genomics, transcriptomics, proteomics, metabolomics, and their imploration in abiotic stress regulation in rapeseed. Some persisting bottlenecks have been highlighted, demanding proper attention to fully explore the omics tools. Further, the potential prospects of the CRISPR/Cas9 system for genome editing to assist molecular breeding in developing abiotic stress-tolerant rapeseed genotypes have also been explained.
