Acclimation of plants to their environment involves mechanisms at all molecular levels and only the complete temporal and spatial pattern adequately describes the acclimation state. The diversity of physiological states realized in plants increases by the essentially infinite combinations of abiotic and biotic stresses, considering duration, impact order, and strength. The interference between stressors involves phenomena of synergism, antagonism, and indifference.

Broccoli is rich in vitamins, antioxidants, minerals, free from calories and fat necessary for a healthy life. The production of broccoli is poor as compared to the developed world because of different biotic and abiotic stress. The nutritional stress is increasing with the passage of time because of low soil fertility and numerous stresses occur in the root zone of plants which reduce the uptake of minerals.

Heat shock proteins 90 (HSP90s) are a highly conserved protein family of cellular chaperones widely found in plants; they play a fundamental role in response to biotic and abiotic stresses. The genome-wide analysis of HSP90 gene family has been completed for some species; however, it has been rarely reported for the tobacco HSP90 genes.

Cotton is an essential fiber producing crop in the world. It also supports additional industries by providing high quality oil and protein in the form of cottonseed cake. Currently, there is an urgent need to increase lint yield, fiber quality, and resistance to biotic and abiotic stresses due to rising pressure from a global population and possible supply shortages from the effects of erratic climate changes. Classic plant breeding and transgenic strategies need more genetic breakthroughs to support the increasing pressure for fiber quantity and quality.

Water availability is a very important factor for the growth and development of plants, which limits the plant production capacity. Rootstocks are widely utilized to improve plants tolerance to various biotic and abiotic stresses. In this study, physiological and biochemical responses of fifteen almond rootstock candidates to drought stress were investigated under in vitro conditions. The shoot tips from fifteen almond rootstock candidates were cultured in MS medium containing 1.0 mg/L BAP, 0.01 mg/L IBA, 30 g/L sucrose and 7 g/L agar.
