Glutathione (GSH) plays a fundamental role in plant defense-signaling network. Recently, we have established the involvement of GSH with ethylene (ET) to combat environmental stress. However, mechanism GSH-ET interplay still remains unexplored. Here, demonstrate that induces ET biosynthesis by modulating transcriptional and posttranscriptional regulations its key enzymes, 1-aminocyclopropane-1-carboxylate synthase (ACS) oxidase (ACO). Transgenic Arabidopsis (Arabidopsis thaliana) plants...
Abstract Background The Himalayan or Indian Mayapple ( Podophyllum hexandrum Royle) produces podophyllotoxin, which is used in the production of semisynthetic anticancer drugs. High throughput transcriptome sequences genomic sequence data from are essential for further understanding podophyllotoxin biosynthetic pathway. Results 454 pyrosequencing a P. cell culture normalized cDNA library generated 2,667,207 raw reads and 1,503,232 high quality reads, with an average read length 138 bp....
The involvement of ethylene and abscisic acid in providing stress tolerance defence response to plants is widely recognized. However, little known about the cross-talk between glutathione with combat planta. Here, transcriptome analysis combined cold osmotic treated Arabidopsis mutants were carried out elucidate crosstalk acid, glutathione. Microarray experiment revealed differential regulation 2313 4131 transcripts ein2 (ethylene insensitive mutant) aba1.6 (abscisic respectively. Functional...
Lectin proteins play an important role in biotic and abiotic stress responses plants. Although the rice lectin protein Osr40c1 has been reported to be regulated by drought stress, mechanism of its tolerance activity not studied so far. In this study, it is shown that expression gene correlates with potential various cultivars. Transgenic plants overexpressing were significantly more tolerant than wild-type Furthermore, ectopic tobacco yielded a similar result. Interestingly, displayed...
The contribution of glutathione (GSH) in stress tolerance, defense response and antioxidant signaling is an established fact. In this study transcriptome analysis pad2.1, Arabidopsis thaliana mutant, after combined osmotic cold treatment has been performed to explore the intricate position GSH network planta. Microarray data revealed differential regulation about 1674 genes pad2.1 amongst which 973 701 were significantly up- down-regulated respectively. Gene enrichment, functional pathway by...
Abstract Under changing environmental conditions, salt stress is a serious threat to agriculture. The R40 family lectins are known be associated with osmotic response, although their mechanism of action remains unclear. Here, we report that Osr40g3, upregulated by salt, improves tolerance but causes pollen sterility and poor seed development in rice when constitutively overexpressed. Osr40g3 knockout lines, on the other hand, display sensitivity no phenotypic aberration. Further studies...
Glutathione (GSH) is known to regulate iron (Fe) deficiency response in plants but its involvement modulating subcellular Fe homoeostasis remains elusive. In this study, we report that the GSH-deficient mutants, cad2-1 and pad2-1 displayed increased sensitivity with significant downregulation of vacuolar exporters, AtNRAMP3 AtNRAMP4, chloroplast importer, AtPIC1. Moreover, mutant accumulated higher levels vacuoles lower chloroplasts compared wild type (Columbia ecotype [Col-0]) under limited...
The contribution of Glutathione (GSH) in drought stress tolerance is an established fact. However, the proteins which are directly or indirectly related to increased level GSH response yet be known. To explore this, here, transgenic tobacco plants (NtGp11) overexpressing gamma-glutamylcysteine synthetase (γ-ECS) was tested for against stress. NtGp11 conferred by germination rate, water retention, recovery, chlorophyll, and proline content compared with wild-type plants. Semi-quantitative...
Glutathione (GSH) is well known to play a crucial role in imparting resistance against various pathogen invasions. Nevertheless, the of GSH regulating miRNA-mediated defense response yet be explored. To decipher GSH-mediated regulation miRNA expression during necrotrophic infection Arabidopsis thaliana, wild-type Col-0 and AtECS1, transgenic line exhibiting enhanced content, were infected with Alternaria brassicicola. AtECS1 plants exhibited as compared wild-type. MiRNA next-generation...
