Macro-algae are a good source of agar oligosaccharides, which can be obtained through bacterial enzymatic hydrolysis. The agarase enzyme secreted by the microorganisms cleaves the cell wall of the algae and releases agar oligosaccharides as degradation products with various applications. Agarolytic bacteria were isolated from the marine algae Kappa...

Abiotic stress can inflict limitations on plant growth, developmental processes and also crop productivity. Here we have portrayed advances in omics tools in the view of conservative and contemporary approaches that could be used to unravel abiotic stress tolerance in rice. Under stressful conditions, plants can develop diverse molecular mechanisms...

The production of biogas by anaerobic digestion (AD) of organic/biological wastes has a firm place in sustainable energy production. A simple and cost-effective anaerobic jar at a laboratory scale is a prerequisite to study the microbial community involved in biomass conversion and releasing of methane gas. In this study, a simulation was carried o...

An easy, efficient and highly reproducible regeneration system was established through organogenesis from leaf base mediated callus of an ethnobotanical hairy shrub Abutilon indicum L. sweet, which is documented to possess pharmaceutically important phytochemicals. Among various explants, leaf bases produced significant callus induction (89%) with...

C3 and C4 grass species (C3: rice, C4: foxtail millet, sorghum, maize) are simultaneously exposed to one or more abiotic stresses (AbS) either independently or in combination, which leads to loss of nutritional value and yield loss. Throughout the life cycle, these plants face unique and combined AbS (CAbS). A large number of studies have been cond...

The diversity in plant metabolites with improved phytonutrients is essential to achieve global food security and sustainable crop yield. Our study using computational metabolomics genome wide association study (cmGWAS) reports on a comprehensive profiling of threonine (Thr) metabolite in rice. Sixteen abiotic stress responsive (AbSR) – Thr metaboli...

The high growth-stimulating effect of plant extract has urged the plant biotechnologists to use natural supplements in the culture media instead of synthetic phytohormones. We advocated the effect of sprouted sorghum extract (SSE) on emergence, in vitro acclimatization, and genetic fidelity in coleoptile derived callus of indica rice variety ADT36....

Transcription factors (TFs) are pivotal players in plant stress signaling and signal transduction pathways. Among the key TFs, NAC, ZF-HD, AP2-EREBP, WRKY and bHLH proteins play crucial roles in the regulation of reprogramming the transcriptome and associated responses in stress. Considering this, genome-wide identification of NAC, ZF-HD, AP2-EREBP...

Combined abiotic stress (CAbS) affects the field grown plants simultaneously. The multigenic and quantitative nature of uncontrollable abiotic stresses complicates the process of understanding the stress response by plants. Considering this, we analyzed the CAbS response of C3 model plant, Oryza sativa by meta-analysis. The datasets of commonly exp...
