In the realm of ornamental crop breeding, the fusion of conventional and novel molecular techniques empowers breeders to fashion innovative varieties featuring distinctive colors, shapes, fragrances, and heightened resistance to both biotic and abiotic stresses. As the floral industry dynamically responds to market demands, it unveils substantial p...
Pigeon pea [Cajanus cajan (L.) Huth], a vital global protein source, faces substantial yield losses due to severe heat stress during reproduction. Genetic diversity exploration, employing GWAS and QTL mapping, reveals markers linked to heat resistance and identifies crucial candidate genes. Heat stress disrupts germination, pod development, and pho...
The important roles of plant microRNAs (miRNAs) in adaptation to nitrogen (N) deficiency in different crop species especially cereals (rice, wheat, maize) have been under discussion since last decade with little focus on potential wild relatives and landraces. Indian dwarf wheat (Triticum sphaerococcum Percival) is an important landrace native to t...
Wheat is the most extensively cultivated food crop worldwide contributing approximately 27% in grain production. Improvement of the nutrient content of wheat varieties along with high productivity is important for global food and nutritional security. Scientists, breeders and food industries adopt numerous strategies to combat the problem of malnut...
Wheat genotype Kharchia is a donor for salt tolerance in wheat breeding programs worldwide; however, the tolerance mechanism in Kharchia is yet to be deciphered completely. To avoid spending energy on accumulating organic osmolytes and to conserve resources for maintaining growth, plants deploy sodium (Na+) ions to maintain turgor. The enhanced abi...
The rise in atmospheric CO2 levels impacts humankind by threatening food and nutritional security. The strong correlation between crop yield and grain weight in cereals is an essential component of yield stability. Further, improving grain protein and mineral nutrient content is a crucial breeding target for cereal crops. The study was performed to...
Micro RNAs (miRNAs) regulate their target genes, that are crucial for plant adaptation to perturbations in environmental variables and nutrient availability by the changes in their own abundance. The greatest limiting factors for the growth of plants are the changing environment and a scarcity of inputs. Nitrogen (N) is an essential nutrient for pl...
Bread wheat (Triticum aestivum L.; Ta) is the staple cereal crop for the majority of the world’s population. Leaf rust disease caused by the obligate fungal pathogen, Puccinia triticina L., is a biotrophic pathogen causing significant economic yield damage. The alteration in the redox homeostasis of the cell caused by various kinds of reactive oxyg...
Wheat crop grown under elevated CO2 (EC) often have a lowered grain nitrogen (N) and protein concentration along with an altered grain ionome. The mechanistic understanding on the impact of CO2 x N interactions on the grain ionome and the expression of genes regulating grain ionome is scarce in wheat. In the present study, the interactive effect of...
Nitric oxide (NO) modulates plant response to biotic and abiotic stresses by S-nitrosylation-mediated protein post-translational modification. Nitrate reductase (NR) and S-nitrosoglutathione reductase (GSNOR) enzymes are essential for NO synthesis and the maintenance of Nitric oxide/S-nitroso glutathione (NO/GSNO) homeostasis, respectively. S-nitro...
Understanding the reproductive stage salinity stress tolerance is a key target for breeding stress tolerant rice genotypes. Nitrate and ammonium are equally important nitrogen forms utilized by rice. We evaluated nitrate and ammonium assimilation during reproductive stage in control and salinity (10dSm⁻¹ using NaCl) stressed rice plants. Osmotic st...
Identification of “donors” possessing superior traits to adapt to low phosphorus (P) soils is a primary requirement to develop efficient crop plants for sustainable agricultural production. Diverse wheat (Triticum aestivum L., 89) and triticale (×Triticosecale Wittmack, 15) genotypes were phenotyped in soil with low and sufficient P for two seasons...
