Rice (Oryza sativa) is a vital food crop and staple diet for most of the world's population. Poor dietary choices have had significant role in development type-2 diabetes population that relies on rice rice-starch-based foods. Hence, our study investigated vitro digestion glycemic indices certain indigenous cultivars factors influencing these indices. Cooking properties were estimated. Further, biochemical investgations such as amylose content, resistant starch content estimated using...
Rice blast resistant gene, Pi54 cloned from rice line, Tetep, is effective against diverse isolates of Magnaporthe oryzae. In this study, we prospected the allelic variants dominant resistance gene a set 92 lines to determine nucleotide diversity, pattern its molecular evolution, phylogenetic relationships and evolutionary dynamics, develop allele specific markers. High quality sequences were generated for homologs gene. Using comparative sequence analysis, InDels variable sizes in all...
Domain swapping and generation of chimeric insecticidal crystal protein is an emerging area insect pest management. The lepidopteran pest, gram pod borer (Helicoverpa armigera H.) wreaks havoc to chickpea crop affecting production. Lepidopteran insects were reported be controlled by Bt (cryI) genes. We designed a plant codon optimized gene (cry1Aabc) using three domains from different cry1A genes (domains I, II, III cry1Aa, cry1Ab, cry1Ac, respectively) expressed it under the control...
Abstract Background Chickpea ( Cicer arietinum L.) is the second most widely grown pulse and drought (limiting water) one of major constraints leading to about 40–50% yield losses annually. Dehydration responsive element binding proteins (DREBs) are important plant transcription factors that regulate expression many stress-inducible genes play a critical role in improving abiotic stress tolerance. Transgenic chickpea lines harbouring factor, Responsive Element-Binding protein 1A from...
Abstract Symbiotic nitrogen fixation (SNF) of transgenic grain legumes might be influenced either by the site transgene integration into host genome or due to constitutive expression transgenes and antibiotic-resistant marker genes. The present investigation confirmed proper nodulation five tested Bt -chickpea events (IPCa2, IPCa4, IPCT3, IPCT10, IPCT13) native Mesorhizobium under field environment. Quantitative variations for traits among were determined IPCT3 was found superior nodule...
Plant disease resistance (R) gene triggers defense mechanisms by detecting non-self or modified self-molecules (elicitors) which results in hypersensitive response.Plant possesses a large number of R-genes with diverse recognition specificities are activated response to variety microbial pathogens.Many studies have shown that variation is the result duplication followed divergence employing tandem segmental duplication, recombination, unequal crossing over, transposable element activity,...
The gram pod borer is a major pest of chickpea, accounting for average annual yield losses to the tune 40-50%. VIP3Aa, class insecticidal protein with different receptor binding site in insect's midgut compared Bt-crystal protein, offers an alternative protection strategy against Lepidopteran insects. Here, we report evaluation genetically engineered chickpea lines harboring codon modified Vip3Aa (cmVip3Aa) insect pest, borer. synthetic modified, cmVip3Aa gene 2,370 bp was sub-cloned plant...
Resistance gene analog (RGA)-anchored amplified fragment length polymorphism (AFLP-RGA) marker system was used in order to evaluate genetic relationships among 22 pigeon pea genotypes with varied responses Fusarium wilt and sterility mosaic disease. Five AFLP-RGA primer combinations (E-CAG/wlrk-S, M-GTG/wlrk-S, M-GTG/wlrk-AS, E-CAT/S1-INV E-CAG/wlrk-AS) produced 173 scorable fragments, of which 157 (90.7%) were polymorphic, an average 31.4 fragments per combination. The rates obtained the...
Sterility mosaic disease (SMD) is a major viral of pigeonpea in southern India. In the present study, simple sequence repeat (SSR) markers were employed to identify those genomic regions associated with resistance Bengaluru isolate SMD through bulked segregant analysis (BSA) approach. Eighty four F 6 recombinant inbred lines (RILs) derived from cross ICP 8863 (susceptible) x BRG 3 (resistant) used. A total 50 hypervariable specific SSR primers (AHSSR) screened for parental polymorphism...
