Chickpea (Cicer arietinum L.) is an important legume crop as a protein source across the world. It is mostly grown on arid and marginal lands where it faces drought stress at different growth stages. Drought stress exerts drastic effects on nutrient uptake, hinders the nodule formation and adversely affects yield and yield components. Generally drought at any growth stage and organizational level is responsible for reduction in economic yield. Significant variability in chickpea germplasm is present on the basis of responses to drought stress in the form of drought escape, drought avoidance and drought tolerance; these mechanisms prevent chickpea crop from harmful effects of drought. Improvement in chickpea germplasm against drought stress could be made by using several breeding approaches, that is introduction, hybridization, mutation breeding, marker-assisted breeding and omic techniques. These breeding approaches, especially marker-assisted breeding and omics, are further strengthened with the availability of the chickpea genome sequence. This review highlighted the significance, status and advances in different breeding strategies for improvement of drought tolerance in chickpea.

“…Plants were harvested 40 days after germination (DAG) and the following data were collected: leghemoglobin (LHb) concentration in nodules was assayed spectrophotometrically (540 nm) using a Drabkin solution as the ''blank'' (Wilson and Reisenauer 1963); leaf soluble protein concentration was determined according to Bradford method (it was assessed with bovine serum albumin as the standard); approximately 2 g leaves of bean were harvested and used for hormone analysis and the extraction and purification of ABA (abscisic acid), IAA (indoleacetic acid), GA 3 (gibberellic acid) and zeatin were determined according to Yurekli et al (2001), Izumi et al (1988) and Nefedieva (2003) with modifications. Briefly, extracts were dissolved in a small volume of methanol and used for HPLC analysis.…”

A greenhouse experiment was performed to evaluate the effects of plant growth-promoting rhizobacteria (PGPR) on nodulation, biological nitrogen fixation (BNF) and growth of the common bean (Phaseolus vulgaris L. cv. Tenderlake). Single and dual inoculation treatments of bean with Rhizobium and/or PGPR were administered to detect possible changes in the levels of and interactions between the phytohormones IAA and cytokinin. Bean plants cv. Tenderlake were grown in pots containing Fluvic Neosol eutrophic (pH 6.5). Fourteen kilogram aliquots of soil contained in 15-l pots were autoclaved. Bean seeds were surface sterilized and inoculated with Rhizobium tropici (CIAT 899-standard strain) alone and in combination with one of the PGPR strains: Bacillus endophyticus (DSM 13796), B. pumilus (DSM 27), B. subtilis (DSM 704), Paenibacillus lautus (DSM 13411), P. macerans (DSM 24), P. polymyxa (DSM 36), P. polymyxa (Loutit L.) or Bacillus sp.(65E180). The experimental design was randomized block design with three replications. Beans co-inoculated with Rhizobium tropici (CIAT899) and Paenibacillus polymyxa (DSM 36) had higher leghemoglobin concentrations, nitrogenase activity and N 2 fixation efficiency and thereby formed associations of greater symbiotic efficiency. Inoculation with Rhizobium and P. polymyxa strain Loutit (L) stimulated nodulation as well as nitrogen fixation. PGPR also stimulated specific-nodulation (number of nodules per gram of root dry weight) increases that translated into higher levels of accumulated nitrogen. The activities of phytohormones depended on their content and interactions with Rhizobium tropici and Paenibacillus and/or Bacillus (PGPR) strains which affect the cytokinin in content in the common bean.

“…ABA appears to modulate the response of plants to a variety of stresses (Zeevaart 1988;Parida and Das 2005). Drought, NaCl, and 'cold tolerance' induce a two to four fold increase in the ABA content of tomato leaves (Plant et al 1991;Yurekli et al 2001;Parida and Das 2005). This similarity in the response suggests that ABA may be a common signal for mediating the response to all three environmental stresses in tomato.…”

Demand for food dramatically increases as the world gets populated, and this problem is of central attention all over the world. Under these circumstances, the balance between food production and consumption depends on the agricultural productivity. However, an increase in the world population and decrease in the agricultural areas due to many reasons such as industrializations, global warming, use of marginal water etc. have been forcing us to use arable lands efficiently as well as saline-prone areas. Low fertile agricultural areas or non-agricultural areas have to be included into agricultural areas if the food production is to be increased. For this reason, many breeding and amelioration strategies have been evaluated so far, however, a few of them have been found successfully in achieving the goals. Physiological, genetical and biochemical mechanisms in plants are quite complex, therefore, it is very difficult to breed a resistant or tolerant plant against stress. To date, breeding or amelioration strategies have followed one direction, either chemical or biological, they then concentrated on either soil or plant itself, have been tested on a few plants in a few local research stations, e.g., use of mycorrhiza. An amelioration strategy both on soil and plant, which could possibly increase the crop production in saline or polluted areas, enable us to improve soil conditions for a long period of time with little effort and expenses. Salt concentration in the soil could be reduced via drainage as well as using high quality water. On the other hand, economically important crop plants have been bred for their resistance to disease and non-pathogenic stress agents such as drought and salinity and some of them have been made commercially available. However, this has not solved the problem globally, especially for the many crop plants which have to be grown in moderate saline conditions, therefore, an effective alternative approach must be found. In recent years, a new method called "bioreclamation" or "phytoremediation" has been introduced in many scientific works and reports. It is one of the efficient methods to improve crop production and quality in saline areas aiming to grow halophytes as companion plants with the crop plants. In this chapter, the effect of salt on plants and plant metabolisms and their phytoremediation strategies have been evaluated so that halophytes could possibly be used as companion plants with crop plants without retarding their growth in saline areas.
