Abiotic Stress Condition

Nitric oxide (NO) is an important signalling molecule employed by plants to control many physiological aspects. This review summarizes that crosstalk between NO/H2O2/Ca2+ signalling pathways that drive pollen tube for sexual reproduction in flowering plants. NO is produced in seeds by both enzymatic and non-enzymatic sources that control many physiological aspects of seeds. The interplay of NO and Reactive oxygen species are likely important players in hormonal crosstalk controlling seed germination and dormancy. Mechanism of seed germination and dormancy is mainly regulated by plant hormones like Abscisic acid (ABA) and Gibberellic acid (GA). Based on mode of action of NO with reference to triggering the germination of crop seeds under abiotic stress condition it is infer that there is a linkage between NO and plant growth regulator production. NO cross-talk with reactive oxygen species (ROS) during abiotic stress condition, modulate the light and hormone depended developmental process in the early stage of plant development. NO action to enhancing abiotic stress tolerance by improving antioxidant enzymes and protection against oxidative damage in many crops are discussed in detail.

<p>Cold<br />shock protein (Csp) essential for organisms to survive in<br />abiotic stress condition. CspB gene has been fused to<br />ubiquitin promoter in the T-DNA region of pCambia 1300int,<br />and introduced into Agrobacterium tumefaciens LBA4404.<br />This research had an objective to transform genetically<br />Nicotiana tabacum cv. Samsun by CspB gene under the<br />control of Ubiquitin promoter and NOS terminator mediated<br />by A. tumefaciens. Leaf discs were co-cultivated with A.<br />tumefaciens LBA 4404. Based on the number of hygromycinresistant<br />calli, the efficiency of transformation was 57.5%. In<br />the selective medium containing 50 μg/l hygromycin, the<br />efficiency of regeneration of transgenic shoots was 82.6%.<br />Based on PCR analysis using primers corresponding to<br />ubiquitin promoter and CspB gene, 18 putative tobacco<br />transgenic containing CspB gene under the control of<br />ubiquitin promoter.</p>

Clp Proteases

Protein malfunction is typically caused by abiotic stressors. To ensure cell survival during conditions of stress, it is important for plant cells to maintain proteins in their respective functional conformation. Self-compartmentalizing proteases, such as ATP-dependent Clp proteases and proteasomes are designed to act in the crowded cellular environment, and they are responsible for degradation of misfolded or damaged proteins within the cell. During different types of stress conditions, the levels of misfolded or orphaned proteins that are degraded by the 26S proteasome in the cytosol and nucleus and by the Clp proteases in the mitochondria and chloroplasts increase. This allows cells to uphold feedback regulations to cellular-level signals and adjust to altered environmental conditions. In this review, we summarize recent findings on plant proteolytic complexes with respect to their protective functions against abiotic and biotic stressors.

Water scarcity is one of the main consequences of changing climate which adversely affects the plant growth and productivity. Enhanced root development results in increased surface area of active absorption for water and nutrient uptake which helps in tolerating abiotic stresses including drought in plants. Trichoderma is well known for its biocontrol and growth promontory effect in plants in addition to alleviate abiotic stress. In our study, thirty isolates of Trichoderma were grown on sterilized cow dung at different moisture content ranges from 5 to 30 percent to investigate their ability to grow and multiply under water stress condition. Mustard plants were grown under glass house condition by treating seeds with selected isolates of Trichoderma subjected to water stress subsequently. All isolates of Trichoderma grew upto 20% moisture whereas only eleven isolates exhibited growth at 10% moisture. Isolate PB23 was only isolate which was able to grow and resulted in 1.0 x109 cfu/g air dried cow dung even at 5% moisture content and induced the tolerance of mustard plants under water stress conditions when applied as seed treatment before sowing.
