Genes for direct methylation of glycine provide high levels of glycinebetaine and abiotic-stress tolerance in Synechococcus and Arabidopsis
Rungaroon Waditee,Md. Nazmul H. Bhuiyan,Vandna Rai,Kenji Aoki,Yoshito Tanaka,Takashi Hibino,Shigetoshi Suzuki,Jun Takano,Andre T. Jagendorf,Tetsuko Takabe,Teruhiro Takabe +10 more
TL;DR: The usefulness of glycine N-methyltransferase genes for the improvement of abiotic stress tolerance in crop plants is demonstrated by finding that betaine levels were higher than those produced by choline-oxidizing enzymes.
Journal ArticleDOI
Combining QTL mapping and transcriptome profiling of bulked RILs for identification of functional polymorphism for salt tolerance genes in rice (Oryza sativa L.).
Awadhesh Pandit,Vandna Rai,Subhashis Bal,Shikha Sinha,Vinod Kumar,Mahesh Chauhan,R.K. Gautam,Rakesh Singh,Prakash C. Sharma,Ashok Kumar Singh,Kishor Gaikwad,Tilak Raj Sharma,Trilochan Mohapatra,Nagendra K. Singh +13 more
TL;DR: Two genes, an integral transmembrane protein DUF6 and a cation chloride cotransporter were not only co-located in the QTL intervals but also showed the expected distortion of allele frequencies in the extreme tolerant and sensitive RILs, and therefore are suitable for future validation studies and development of functional markers for salt tolerance in rice.
Journal ArticleDOI
Mapping QTLs for Salt Tolerance in Rice (Oryza sativa L.) by Bulked Segregant Analysis of Recombinant Inbred Lines Using 50K SNP Chip
Sushma Tiwari,Krishnamurthy Sl,Vinod Kumar,Balwant Singh,Atmakuri Ramakrishna Rao,Amitha Mithra Sv,Vandna Rai,Ashok Kumar Singh,Nagendra K. Singh +8 more
TL;DR: A method for rapid identification of QTLs for reproductive stage salt tolerance in rice using bulked segregant analysis (BSA) of bi-parental recombinant inbred lines (RIL).
Journal ArticleDOI
Single-copy gene based 50 K SNP chip for genetic studies and molecular breeding in rice
Nisha Singh,Nisha Singh,Pawan Kumar Jayaswal,Kabita Panda,Paritra Mandal,Vinod Kumar,Balwant Singh,Shefali Mishra,Yashi Singh,Renu Singh,Vandna Rai,Anita Gupta,Tilak Raj Sharma,Nagendra K. Singh +13 more
TL;DR: The design and validation of a unique genic-SNP genotyping chip for genetic and evolutionary studies as well as molecular breeding applications in rice showed high success rate and reproducibility and its efficacy was validated for analysing background recovery in improved mega rice varieties with submergence tolerance developed through marker-assisted backcross breeding.
Journal ArticleDOI
Differences in the arbuscular mycorrhizal fungi-improved rice resistance to low temperature at two N levels: aspects of N and C metabolism on the plant side.
TL;DR: The mycorrhizal rice with the low N supplementation had more positive feedback from the symbiotic AMF, as indicated by accelerated N and C metabolism of rice possibly involving jasmonic acid (JA) and the up-regulation of enzyme activities for N andC metabolism.
