BACKGROUND: Climate change, including higher temperatures (HT) has a detrimental impact on wheat productivity and modeling studies predict more frequent heat waves in the future. Wheat growth can be impaired by high daytime and nighttime temperature at any developmental stage, especially during the grain filling stage. Leaf chlorophyll content, leaf greenness, cell membrane thermostability, and canopy temperature have been proposed as candidate traits to improve crop adaptation and yield potenti...

Proline is one of the most important compatible osmolyte in cells, which accumulates in response to various stresses, including salt, water deficit, heavy metal, pathogen infection and extreme temperature. In this study, a growth chamber was employed to simulate heat environment for Avicennia marina seedlings. We detected some physiological indices in the leaves of A. marina at 40 degrees C, including the activity of delta-1-pyrroline-5-carboxylate synthase (P5CS), the content of free proline an...

Prevailing conditions of the climate have had a drastic effect on global food security. Various types of stresses have been producing havoc by reducing crop production. One of the primary causes has been observed in the form of drought. Drought generally has various kinds of impacts on human life, but its main victim is food crops. A plant has specific defense systems to combat and stay unchanged in an environment with water stress, but this ability decreases as the lack of water increases for a...

Global warming has an adverse impact on agriculture and food security is in doldrums around the world. A sharp increase in the temperature of earth is expected and may lead to ~ 1.8–4 °C rise in average earth temperature by the year 2100. Thus, heat stress is a critical factor for plant growth development and crop yield. Chickpea, which is an important leguminous crop and rich source of proteins is also a heat sensitive crop but high temperature exceeding 35 °C inhibit its productivity. Climate-...

Nanoparticles (NPs) are extremely small units occurring at the scale of nanometers (nm) which have been synthesized from both chemical and natural sources. The applicability of these particles has expanded over the past decade so that thousands of useful applications are now attributed to these remarkable particles. The impact of nanotechnology on medicine and other branches of material science suggests that researchers can craft particles for improving and developing agricultural products. The ...

Abstract Given the limitation of crop production in Cd-polluted areas, the identification and selection of plant genotypes tolerant to Cd stress are of great significance. In the present work, we show the existence of genotypic variation for Cd tolerance in common bean. The laboratory screening of 25 bean genotypes indicated a significant positive correlation of the mean productivity (MP) and the geometric mean productivity (GMP) with plant fresh weight both in control and Cd-treated plants. A p...

Soil salinity is major constraint for wheat production globally and breeding wheat cultivars for salt tolerance by conventional means is difficult. Therefore, understanding molecular components associated with salt tolerance is needed to facilitate breeding for salt tolerance in wheat. In this investigation, quantitative trait loci (QTL/s) associated with salt tolerance were identified using recombinant inbred lines (RILs) developed from a cross between Kharchia 65 (KH 65) and HD 2009 cultivars....
