To enhance resistance to blast and BB, we employed marker-assisted backcross breeding to introgress the resistance genes into the genetic background of BRRI dhan48. The resistant (R) genes <em>Pi9</em>, <em>Pb1</em>, <em>Xa4</em>, <em>xa13</em>, and <em>Xa21</em> were introgressed from Pi9-US2, Pb1-US2, and IRBB58, respectively. The <em>Pb1</em> gene strengthens blast resistance in rice by interacting with WRKY45 transcription factor to modulate salicylic acid and phytoalexin pathways, while the <em>Pi9</em> gene triggers a signaling cascade involving reactive oxygen species (ROS) production and hormones like jasmonic acid and ethylene activation to enhance defense responses. <em>Xa4</em> strengthens the cell wall via WAK (cell wall-associated kinase) protein, hindering pathogen invasion, <em>xa13</em> disrupts SWEET (Sugar Will Eventually be Exported Transporter) protein function to limit sugar availability for <em>Xanthomonas oryzae</em> pv. <em>oryzae</em> (Xoo). <em>Xa21</em> triggers mitogen-activated protein kinases (MAPKs)-mediated signaling cascades, leading to the activation of WRKY transcription factors that suppress bacterial proliferation. For that, triple cross was made, followed by repeated backcrosses, self-pollinations, and marker-assisted selection to generate BC<sub>3</sub>F<sub>5</sub> progeny. Chi-square analysis of 380 BC<sub>3</sub>F<sub>2</sub> individuals confirmed a monogenic inheritance pattern for blast and BB resistance traits. Finally, we selected 32 advanced lines, and among them nineteen lines possessed all these 5 R genes, i.e., <em>Pi9</em>, <em>Pb1</em>, <em>Xa4</em>, <em>xa13</em>, and <em>Xa21</em><sub><em>,</em></sub> while eight lines consisted of 4 R genes in different combinations. The disease rating of the advanced lines varied from 0 to 5 for both blast and BB diseases, while BRRI dhan48 had a disease rating ranging from 7 to 9. The lines G10, G25, G16, G31, G9, G2, and G20 demonstrated significantly higher grain yield (7.73, 7.72, 7.70, 7.65, 7.64, 7.59, and 7.58 t ha<sup>−1</sup>, respectively) than the parent (7.00 t ha<sup>−1</sup>). Investigation of marker trait association showed that molecular markers were negatively linked with blast and BB diseases. So, gene introgression by marker-assisted backcrossing (MABB) offers a robust and efficient way to identify and validate candidate genes with high precision for the development of durable, resistant rice breeding lines. These multiple disease resistant advanced lines may use as a potential genetic stock or incorporate with other desired genes for ensuring sustainable rice production under changing climatic conditions.</div></div>","PeriodicalId":38041,"journal":{"name":"Plant Gene","volume":"42 ","pages":"Article 100505"},"PeriodicalIF":2.2,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143808219","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}

Developing natural colored cotton (NCC) varieties is crucial for cotton fiber utilization due to their eco-friendly properties. Manipulation of anthocyanin synthesis is an effective strategy for creating novel NCCs. Our previous research revealed enhanced anthocyanin accumulation in an empurpled <em>Gossypium hirsutum</em> mutant, <em>HS2</em>, but the regulatory mechanism has not been fully elucidated. In this study, we employed an integrated analysis of RNA sequencing, small RNA (sRNA) sequencing, and degradome sequencing to assess the expression patterns and potential roles of sRNAs in the development of the empurpled phenotype in <em>HS2</em>. Our findings revealed that the expression profiles of sRNAs are highly similar between the wild type and the mutant, with only 11 miRNAs and 761 siRNAs showing significant expression variation. Eight miRNAs and one siRNA exhibited inverse regulation with their targets, which were not directly involved in regulating anthocyanin biosynthesis. Notably, degradome data analysis identified interactions between miR395 and ATP sulfurylase genes (<em>APS1</em> and <em>APS3</em>). Further assessment determined down-regulation of miR395 and up-regulation of <em>APS</em> genes in <em>HS2</em>, as well as the enhanced biosynthesis of cysteine and glutathione. These results suggest that miRNA mediated post-transcriptional regulation might not be the primary mechanism driving anthocyanin enhancement in <em>HS2</em>. Instead, the miR395-<em>APS</em> modules are possibly involved in modulating cellular processes to cope with the increased anthocyanin levels. Overall, this study deepens our understanding of the molecular mechanisms underlying the empurpled phenotype in <em>HS2</em> and facilitates its future use in NCC breeding.</div></div>","PeriodicalId":38041,"journal":{"name":"Plant Gene","volume":"42 ","pages":"Article 100504"},"PeriodicalIF":2.2,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143792513","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}

We examine how epigenetic mechanisms—such as DNA methylation, histone modifications, and non-coding RNAs—regulate gene expression in coordination with hormonal signalling pathways. Phytohormones, including abscisic acid, jasmonic acid, ethylene, salicylic acid, auxins and cytokinins, are central to these processes, influencing key morphological and physiological adaptations, such as stomatal regulation, cuticle thickness, water retention, and improved water-use efficiency. The review synthesizes current knowledge on the molecular and hormonal networks underlying these adaptations and their impact on leaf architecture and metabolism. Despite advancements, critical gaps remain in identifying the specific genes and pathways involved, understanding the longevity of epigenetic marks, and elucidating the intricate cross-talk between phytohormones during drought stress memory.
