BACKGROUND The regulation of ribosomal proteins in plants under stress conditions has not been well studied. Although a few reports have shown stress-specific post-transcriptional and translational mechanisms involved in downregulation of ribosomal proteins yet stress-responsive transcriptional regulation of ribosomal proteins is largely unknown in plants. METHODOLOGY/PRINCIPAL FINDINGS In th...
A combination of hot water (a rinse at 62 degrees C for 20 s) and conditioning (pre-storage at 16 degrees C for 7 d) treatments synergistically reduced chilling injury development in grapefruit (Citrus paradisi, cv. "Star Ruby") during cold storage at 2 degrees C, suggesting that the treatments may activate different chilling tolerance responses. To study the molecular mechanisms involved, chil...
Being a prime source of food, agriculture sustains almost all life-forms on the Earth. However, apart from natural calamities, a range of man-made activities are causing significant increase in environmental stresses for plant growth. Adverse conditions, in turn, restrict crop plants to reach their full genetic potential of producing high yield (Anjum et al., 2014). Also, agriculture is under p...
The Sko1p transcriptional repressor regulates a subset of osmoinducible stress defense genes in Saccharomyces cerevisiae by binding to cAMP-responsive elements. We have reported previously that in response to stress Sko1p is phosphorylated by the stress-activated Hog1p mitogen-activated protein kinase, which disrupts its interaction with the Ssn6p x Tup1p corepressor. Here we report that other ...
Heat stress is a major abiotic stress posing a serious threat to plants. Heat-responsive mechanisms in plants are complicated and fine-tuned. Heat signaling transduction and photosynthesis are highly sensitive. Therefore, a thorough understanding of the molecular mechanism in heat stressed-signaling transduction and photosynthesis is necessary to protect crop yield. Current high-throughput prot...
Small non-coding RNAs (sRNAs) namely microRNAs (miRNAs) and trans-acting small interfering RNAs (tasi-RNAs) play a crucial role in post-transcriptional regulation of gene expression and thus the control plant development and stress responses. In order to identify drought-responsive miRNAs and tasi-RNAs in sorghum, we constructed small RNA libraries from a drought tolerant (M35-1) and susceptibl...
Drought stress is an inevitable factor that disturbs the production of plants by altering morphological, physiological, biochemical, and molecular functions. Breeding for drought tolerance requires a complete understanding factors controlling stress-responsive pathways. The plant responds to adopting four mechanisms: avoidance, escape, tolerance, recovery. Traditional plant-breeding tools have ...
Pearl millet (Pennisetum glaucum L.) is affected by drought stress, affecting crop productivity and survival. Long non-coding RNAs (lncRNAs) are reported to play a vital role in the response stress. LncRNAs represent major part of non-protein coding present prevalently. These involved various biological processes, which may functionally act as RNA rather than getting transcribed protein. We tar...
