Abstract:
... Cadmium (Cd) is one of the most toxic heavy metals faced by plants and threatens human health through the food chain. There are many similarities across species in response to cadmium stress, yet understanding of the underlying conserved molecular mechanisms is still lacking. Here, we obtained a conserved set of genes involved in the response to Cd stress in typical monocotyledonous and dicotyledo ...

Abstract:
... Direct seeding of rice (Oryza sativa L.) has since long been viewed as a potential alternative to unsustainable water-intensive transplanted rice (TPR) world-over, but heavy infestation of a variety of weed species limits the large-scale adoption of direct-seeded rice (DSR) cultivation. Hence, a 2-year field investigation was carried-out in a spilt-plot design, at Banaras Hindu University, Varanas ...

The results showed that hybrid breeding led to increases in the Shannon index of cultivar diversity by 29–184% during the period 2011–2015 compared with the period 1986–1990 for 10 major hybrid rice‐producing provinces in China. There was a significant exponential relationship b ...

Abstract:
... Because of global warming, the ripening period of rice (Oryza sativa L.) is becoming hotter in Japan, and there is concern that eating quality will decline as a result. Amylopectin is the largest component of rice endosperm starch and its short-chain content has a considerable effect on the eating quality of cooked rice. Here we investigated the effect of high temperature during ripening on amylop ...

Previous pangenomic studies have identified certain functional differences between core and dispensable genes. However, identifying if a gene belongs to the core or dispensable portion of the genome requires the construction of a pangenome, which involves sequenci ...

Abstract:
... During the course of evolution, different ecotypes of rice (Oryza sativa L.) have evolved distinct strategies to cope with submergence stress. Such contrasting responses are mediated by plant hormones that are principle regulators of growth, development and responses to various biotic and abiotic stresses. These hormones act cooperatively and show extensive crosstalk which is mediated by key regul ...
