In the regulation of gene expression, particularly abiotic-stress tolerance characteristics in plants, inducible promoters play an essential role in ensuring the endurance and productivity of crops. In several previous studies, the ZmDREB2.7 gene and some DNA polymorphisms in its promoter have been shown to enhance drought tolerance traits in maize (Zea mays L.).

Auxins play an important role in plant growth and development; the auxins responsive gene; auxin/ indole-3-acetic acid (Aux/IAA), small auxin-up RNAs (SAUR) and Gretchen Hagen3 (GH3) control their mechanisms. The GH3 genes function in homeostasis by the catalytic activities in auxin conjugation and bounding free indole-3- acetic acid (IAA) to amino acids.

Citrus plants are commercially propagated by grafting, with the rootstock variety influencing a number of horticultural traits, including drought tolerance. Among the different rootstock varieties available for citrus propagation, ‘Rangpur’ lime is known to confer enhanced tolerance to drought as compared to other citrus rootstocks.

Drought tolerance is accompanied by number of traits and they are regulated by the many genes, hence targeting single gene against moisture stress will not be effective in crop improvement. Use of transcription factors (TFs) to target corresponding multigene is current trend. As per the many research findings, dehydration responsive element binding proteins (DREB) are reported as an important TFs that known to induces number of abiotic stress-related genes and impart the stress tolerance in plants.

Studies on soybean GmNAC085 transcription factor revealed that the gene expression in plants was induced by water shortage treatments and its overexpression in the model plant Arabidopsis displayed improved plant tolerance characteristics towards drought stress. In this study, we continued analyzing the biological functions of GmNAC085 using transgenic soybean system overexpressing GmNAC085 gene, by targeting at a number of plant physiological features and biochemical activities in response to limited water growing condition.

Premature leaf senescence induced by external stress conditions, e.g. drought stress, is a main factor for yield losses in barley. Research in drought stress tolerance has become more important as due to climate change the number of drought periods will increase and tolerance to drought stress has become a goal of high interest in barley breeding.

Ethylene is a phytohormone known for inducing a triple response in seedlings, leaf abscission and other responses to various stresses. Several studies in model plants have evaluated the importance of this hormone in crosstalk signaling with different metabolic pathways, in addition to responses to biotic stresses.

Abiotic stresses are major constrains which adversely affect the plant growth and productivity. Among all abiotic stresses, drought is considered as one of the major constraints on agricultural productivity worldwide and is likely to further increase. Hence the need of the hour is to formulate the strategies that can minimize the loss in crop production under drought conditions. One of them being the exploitation of soil microbes which have the capacity to overcome the adverse effects of drought stress.

MYB-CC transcription factors (TFs) genes have been demonstrated to be involved in the response to inorganic phosphate (Pi) starvation and regulate some Pi-starvation-inducible genes. However, their role in drought stress has not been investigated in bread wheat.

Wheat is an important cereal crop grown worldwide primarily for chapati, bread and biscuits. Target specific wheat breeding and quality improvement programs focus on developing genetically superior, high yielding, disease resistant cultivars with desired quality that are adapted to different growth environments. Drought refers to the condition of reduced soil moisture which induces several changes in crops i.e., morphological, biological, physiological and molecular changes. It also causes reduction in crop yield or in some cases cause crop failure.

Endophytes are microorganisms mostly bacteria and fungi that lives partially or completely its life cycle inside living plant tissue without causing adverse negative symptoms. Endophytes play a major role in structuring shaping processes of plant such as colonization, competition, coexistence and soil nutrient dynamics. Some endophytes promote growth of their host plants by enhancing the host‟s ability to take up nitrogen and phosphorus.

The occurrence of drought stress at seed filling stage is known to cause severe yield reduction in soybean especially where the crop is grown in rainfed conditions. Screening of large germplasm lines under natural drought conditions is extremely difficult to execute due to unusual rains. In the present study, about 328 germplasm lines are screened for terminal drought tolerance by spraying 0.2% of potassium iodide (KI) at R5 stage and the tolerant lines were again retested under similar conditions in the subsequent year.

Legumes are well recognized for their nutritional and health benefits as well as for their impact in the sustainability of agricultural systems. The threatening scenario imposed by climate change highlights the need for concerted research approaches in order to develop crops that are able to cope with environmental stresses, while increasing yield and quality. During the last decade, some physiological components and molecular players underlying abiotic stress responses of a broad range of legume species have been elucidated.

Cytokinin (CK) is an important phytohormone, which not only plays significant role in plant development but also involves in mediating plant stress tolerance. Previous studies showed that the drought tolerance can be improved by stress-inducible overexpression of adenine isopentenyl transferase (IPT), which is a critical enzyme in CKs biosynthesis.

Leaf rolling (LR), particularly in crops, is a dehydration avoidance mechanism that results from water loss in plants under drought conditions. Two maize cultivars (Zea mays L.) differing in their tolerance to drought (cultivar Side was selected as stresstolerant and cultivar Karaçay was selected as stress-sensitive) under PEG-induced drought stress were used in this study to understand the effects of polyamines (PAs) on LR response and the role of the antioxidant system in the delayed LR process.

Over the past decade, our understanding of plant adaptation to environmental stress, including both constitutive and inducible determinants, has grown con- siderably. This book focuses on stress caused by the inanimate components of the environment associated with climatic, edaphic and physiographic factors that substantially limit plant growth and survival. Categorically these are abiotic stresses, which include drought, salinity, non-optimal temperatures and poor soil nutrition.
