Hybrid seeds are used for stimulated crop production, as they harness heterosis. The achievement of complete male-sterility in the female-parent and the restored-fertility in F1-hybrids are the major bottlenecks in the commercial hybrid seed production. Here, we report a male sterility-fertility restoration system by engineering the in most nutritive anther(More)
Induction of male sterility followed by successful outcrossing is a prerequisite for hybrid seed production. In this article, we have identified a novel use of the BECLIN 1 gene of Arabidopsis, in inducing male sterility in plants, when expressed in the anther tapetum of tobacco. We also report a stringently regulated and high-level expression of the(More)
Amyloid-beta (Aβ) peptide mediates several neurodegenerative diseases. The 42 amino acid (Aβ1-42) is the predominant form of peptide found in the neuritic plaques and has been demonstrated to be neurotoxic in vivo and in vitro. The availability of large quantities of Aβ peptide will help in several biochemical and biophysical studies that may help in(More)
The nuclear export of macromolecules is facilitated by the nuclear pore complexes (NPCs), embedded in the nuclear envelope and consists of multi-protein complexes. MEX67 is one of the nuclear export factor responsible for the transport of the majority of cellular mRNAs from the nucleus to the cytoplasm. The mechanism of mRNA transport through NPCs is(More)
Mycobacterium tuberculosis is the etiological agent of tuberculosis in humans and is responsible for more than two million deaths annually. M. tuberculosis isocitrate lyase (MtbICL) catalyzes the first step in the glyoxylate cycle, plays a pivotal role in the persistence of M. tuberculosis, which acts as a potential target for an anti-tubercular drug. To(More)
The maintenance of cellular redox homeostasis is a crucial adaptive problem faced by parasites, and its disruption can shift the biochemical balance toward the host. The thioredoxin (Trx) system plays a key role in redox metabolism and defense against oxidative stress. In this study, biochemical experiments were performed on Fasciola gigantica Thioredoxin1(More)
Fasciola gigantica is the causative organism of fascioliasis and is responsible for major economic losses in livestock production globally. F. gigantica thioredoxin1 (FgTrx1) is an important redox-active enzyme involved in maintaining the redox homeostasis in the cell. To identify a potential anti-fasciolid compound, we conducted a structure-based virtual(More)
We report a novel class of glutathione S-transferase (GST) from the model cyanobacterium Synechocystis PCC 6803 (sll1545) which catalyzes the detoxification of the water pollutant dichloroacetate and also shows strong glutathione-dependent peroxidase activity representing the classical activities of zeta and theta/alpha class respectively. Interestingly,(More)
Glutathione S-transferases (GSTs) are multifunctional enzymes present in virtually all organisms. Besides having an essential role in cellular detoxification, they also perform various other functions, including responses in stress conditions and signaling. GSTs are highly studied in plants and animals; however, the knowledge regarding GSTs in cyanobacteria(More)
Isocitrate lyase (ICL), a potential anti-tubercular drug target, catalyzes the first step of the glyoxylate shunt. In the present investigation, we studied the conformational flexibility of MtbICL to better understand its stability and catalytic activity. Our biochemical results showed that a point mutation at Phe345, which is topologically distant (>10 Å)(More)
