“…1 Ten days old seedlings were treated with 20% polyethylene glycol-6000 (dehydration), 200mM NaCl (salinity), 100mM ABA, 4°C (cold), 10mM hydrogen peroxide (H 2 O 2 ) and 100μM ethephone as described elsewhere. 7 Total RNA was isolated during 1, 6, 12 and 24 h after stress treatments by using TRIzol Reagent (Life technologies) as described earlier. 8 For, northern blot analysis about 20μg of total RNA from each sample was electrophoresed on 1.2% denaturing gel.…”

“…Being a hardy crop, it is relatively easy to grow finger millet under stressful regimes, without hampering the net productivity. Tolerance to drought stress may be attributed to an efficient antioxidant potential and increased signal perception (Puranik et al 2011). However, there exists a huge variation in the degree of adaptability to drought, among different varieties of finger millet.…”

The study presents the impact of drought stress on five finger millet varieties (PR202, VL146, VL315, PES400 and VR708), representing contrasting areas of Indian sub-continent. Drought stress induced increase in the activity of superoxide dismutase, ascorbate peroxidase and glutathione reductase was higher in PR202 and VL315, while the activity was lower in the varieties PES400 and VR708. Ascorbate peroxidase : superoxide dismutase ratio, which is a crucial factor in alleviating drought stress, was higher in varieties PR202 and VL315, whilst the varieties PES400 and VR708 exhibited a lower ratio under stress. The variety PES400 recorded maximum stress induced damage, as indicated by higher accumulation of malondialdehyde and hydrogen peroxide; whereas the variety PR202 recorded least stress induced cytotoxic damage. The results clearly indicate that better drought tolerance of the variety PR202 is positively related to the capacity of its antioxidant system to scavenge reactive oxygen species, resulting in a reduced incidence of oxidative damage. Ascorbate peroxidase : superoxide dismutase ratio is found to be a critical factor governing the stress tolerance potential of different varieties. Therefore, varieties PR202 and VL315 were found to be tolerant while PES400 was susceptible to drought stress.

“…Other time series studies include the studies of rice root under low potassium [103], cassava under cold stress [104], and soybean subjected to Pseudomonas syringae infection [105]. The other widely reported experimental design is the comparative transcriptome study performed among crop accessions with different degrees of stress tolerance, such as the study of soybean accessions exhibiting differential tolerance toward low potassium [106], rice cultivars with contrasting abilities to withstand drought [107] and chilling [108], wheat with differential drought tolerance [109], and Medicago [110] and foxtail millet [111] cultivars with differential salt tolerance.…”

Abiotic and biotic stresses lead to massive reprogramming of different life processes and are the major limiting factors hampering crop productivity. Omics-based research platforms allow for a holistic and comprehensive survey on crop stress responses and hence may bring forth better crop improvement strategies. Since high-throughput approaches generate considerable amounts of data, bioinformatics tools will play an essential role in storing, retrieving, sharing, processing, and analyzing them. Genomic and functional genomic studies in crops still lag far behind similar studies in humans and other animals. In this review, we summarize some useful genomics and bioinformatics resources available to crop scientists. In addition, we also discuss the major challenges and advancements in the "-omics" studies, with an emphasis on their possible impacts on crop stress research and crop improvement.
