In the present study, 200 genome-wide spanned simple sequence repeat (SSR) markers were used for estimation of genetic diversity and identification of genetically divergent parental combinations in a panel of 28 parental lines of Indian mustard comprising of 21 cytoplasmic male sterile (CMS) ‘A' lines and 7 restrorer ‘R' lines.

Allele number varied from 2 to 6 with a mean value of 3.27 alleles per SSR marker. PIC values ranged from 0.23 to 0.7 with a mean value of 0.38 per SSR marker. Gene diversity values were in the range of 0.27–0.75 with average value of 0.47, inferring the presence of a moderate level of genetic diversity in the plant material.

The LOX gene family has been thoroughly investigated under biotic and abiotic stressors; however, knowledge of their functions on callus induction and regeneration in cotton is still scarce. This study identified 34, 38, 23, and 20 LOX genes in the <em>Gossypium hirsutum</em>, <em>Gossypium barbadense</em>, <em>Gossypium arboreum</em>, and <em>Gossypium raimondii</em>, respectively.

Direct-sown rice (DSR) is emerging as an alternative to transplanted rice (TPR) to save water. Performance of rice under DSR conditions varies greatly. While the molecular basis of adaptive plasticity of rice is subtle, tolerance to environmental stresses in crops is important for sustainable food production/security. The present study explores the molecular basis of adaptive/genetic plasticity in rice grown by different methods of planting, emphasising the concept of cumulative transcriptional memory. Our findings of comparative RNA-seq analysis highlighted differential gene expression with ∼6130 genes exclusively upregulated in the leaf of Nagina22 (N22) in contrast to only ∼3540 genes upregulated exclusively in the leaf of IR64 grown by dry/direct-sowing. In addition, our findings revealed that numerous genes showing upregulation in N22 were detected downregulated in IR64 that highlight distinct molecular strategies adopted by the rice cultivars. By activating diverse sets of genes coding for transcription factors, growth-regulating factors, translational machinery, nutrient-reservoirs, chromatin organization/epigenetic modifications, cell cycle/division, carbohydrate metabolism, etc., N22 adapts more effectively/efficiently to direct-sown conditions. Complementarity between these factors emerged to play important roles in adaptability of N22 to fluctuating environmental conditions. This helps adjust physio-biochemical responses of N22 to multiple abiotic/biotic stresses experienced under DSR conditions. Thus, our findings make a foundation for the development of molecular markers to facilitate varietal development of DSR for improved water productivity and sustainable agriculture.</div></div>","PeriodicalId":38041,"journal":{"name":"Plant Gene","volume":"43 ","pages":"Article 100515"},"PeriodicalIF":2.2,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143852107","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}

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 BC₃F₅ progeny. Chi-square analysis of 380 BC₃F₂ 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>_<em>,</em> while eight lines consisted of 4 R genes in different combinations.

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.
