Effect of Drought Acclimation on Drought Stress Resistance in Okra Seedlings
Erzincan Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2023Öz Bu çalışmada bamyada (Abelmoschus esculentus L.) fide döneminde kuraklık aklimasyonunun etkileri araştırılmıştır. Bu amaçla, aklimasyon yapılmamış ve stressiz (NA), aklimasyon yapılmış ve stressiz (DA), aklimasyon yapılmamış ve kuraklık stresli (NAS), aklimasyon yapılmış ve kuraklık stresli (DAS) olmak üzere dört farklı sulama uygulaması ...

Salinity and Drought Stress in Rice
1990Understanding the physiological responses of plants to saline soils and drought is more important today than ever before since genetic engineering is providing techniques by which these responses can be altered. This paper reviews some of the current ideas about how osmotic and ionic stresses affect plants, and about physiological adaptations that ...

Molecular responses to drought and cold stress
Current Opinion in Biotechnology, 1996A variety of plant genes are induced by drought and cold stress, and they are thought to be involved in the stress tolerance of the plant. At least five signal transduction pathways control these genes: two are dependent on abscisic acid (ABA), and the others are ABA-independent.

Plant Response to Drought Stress
2019This chapter describes the principles of water transport and its importance, followed by a discussion of the effect of water stress on tree performance and the main physiological strategies that trees use to cope with this stress. It reviews the molecular mechanisms that trees use to cope with water stress, with illustrations of how those mechanisms ...

Cold, salinity and drought stresses: An overview
Archives of Biochemistry and Biophysics, 2005World population is increasing at an alarming rate and is expected to reach about six billion by the end of year 2050. On the other hand food productivity is decreasing due to the effect of various abiotic stresses; therefore minimizing these losses is a major area of concern for all nations to cope with the increasing food requirements. Cold, salinity

Drought Stress in Plants: An Overview
2012Drought is one of the major constraints limiting crop production worldwide. Crop growth models predict that this issue will be more severe in future. Drought impairs normal growth, disturbs water relations, and reduces water use efficiency in plants.

Proteomic responses of drought-tolerant and drought-sensitive cotton varieties to drought stress
Molecular Genetics and Genomics, 2016Drought, one of the most widespread factors reducing agricultural crop productivity, affects biological processes such as development, architecture, flowering and senescence. Although protein analysis techniques and genome sequencing have made facilitated the proteomic study of cotton, information on genetic differences associated with proteomic ...

Drought and Salt Stress in Cereals
2015Abiotic stresses, such as salinity, drought, extreme temperatures, chemical toxicity and oxidative stress represent a grave threat to agriculture dramatically affecting the crop production around the world. Climate changes are projected to have a significant impact on temperature and precipitation profiles increasing the incidence and severity of ...

Drought, Desiccation, and Oxidative Stress
2011Reactive oxygen species (ROS) are noxious but inevitable by-products of aerobic metabolism. Singlet oxygen 1O2, the oxygen radical anion O 2 − , the extremely toxic hydroxyl radical OH•, and finally H2O2 originate in photosynthesis, but O 2 − and H2O2 can also arise in the mitochondrial electron transport, and H2O2 is a normal intermediate in ...

Drought Stress and Mycorrhizal Plant
2013It is recognized that mycorrhizas permit the plant to perform more efficiently under stressful and unfavorable conditions. Recent reports on plant growth under drought stress and mycorrhizas account for 3.7 % of the published papers on mycorrhizas. Stress affects soil physical and chemical properties, as well as plant performance, which affect soil ...
