Transgenic Peanut (Arachis hypogaea L.) Overexpressing mtlD Gene Showed Improved Photosynthetic, Physio-Biochemical, and Yield-Parameters under Soil-Moisture Deficit Stress in Lysimeter System
Peanut, an important oilseed crop, frequently encounters drought stress (DS) during its life cycle. In this study, four previously developed mtlD transgenic (T) peanut lines were used for detailed characterization under DS, at the reproductive stage using lysimeter system under controlled greenhouse conditions. In dry-down experiments, T lines maintained better photosynthetic machinery, such as...
متن کاملStress Inducible Expression of AtDREB1A Transcription Factor in Transgenic Peanut (Arachis hypogaea L.) Conferred Tolerance to Soil-Moisture Deficit Stress
Peanut, an important oilseed crop, is gaining priority for the development of drought tolerant genotypes in recent times, since the area under drought is constantly on the rise. To achieve this, one of the important strategies is to genetically engineer the ruling peanut varieties using transcription factor regulating the expression of several downstream, abiotic-stress responsive gene(s). In t...
متن کاملThe Peanut (Arachis hypogaea L.) Gene AhLPAT2 Increases the Lipid Content of Transgenic Arabidopsis Seeds
Lysophosphatidic acid acyltransferase (LPAT), which converts lysophosphatidic acid (LPA) to phosphatidic acid (PA), catalyzes the addition of fatty acyl moieties to the sn-2 position of the LPA glycerol backbone in triacylglycerol (TAG) biosynthesis. We recently reported the cloning and temporal-spatial expression of a peanut (Arachis hypogaea) AhLPAT2gene, showing that an increase in AhLPAT2 t...
متن کاملPeanut (Arachis hypogaea L.) Omics and Biotechnology in China
Peanut is one of the most important crops in the world, both for vegetative oil and as a protein source. Biotechnology approaches provide promising ways to increase peanut productivity, either through improved seed quality or stress resistance. These approaches require the identification of genes that control important agronomical traits, the understanding of gene regulation and metabolic pathw...
متن کاملImproved drought and salt tolerance in transgenic Arabidopsis overexpressing a NAC transcriptional factor from Arachis hypogaea.
The NAC (NAM, ATAF, and CUC) proteins share a highly conserved NAC domain and constitute a large family of plant-specific transcriptional factors. We have isolated a drought-induced NAC gene from Arachis hypogaea, named AhNAC2 (Arachis hypogaea NAC2) but its specific role remains unknown. In this study, we found that transgenic Arabidopsis overexpressing AhNAC2 lines were hypersensitive to ABA ...
