“…Under a constitutive promoter, over-expression of DREB1A proved to be harmful under normal conditions, whereas it was beneficial when a stress was applied. DREB1A expression was reduced in peanuts by using the stress inducible promoter from rd29A instead of CaMV35S (Puli et al, 2021). Peanut genotypes with high transpiration efficiency (TE) and stomatal conductance have largely failed to develop due to the difficulty of solving the stress tolerance problem.…”

The change in climatic conditions is the major cause for decline in crop production worldwide. Decreasing crop productivity will further lead to increase in global hunger rate. Climate change results in environmental stress which has negative impact on plant-like deficiencies in growth, crop yield, permanent damage, or death if the plant remains in the stress conditions for prolonged period. Cold stress is one of the main abiotic stresses which have already affected the global crop production. Cold stress adversely affects the plants leading to necrosis, chlorosis, and growth retardation. Various physiological, biochemical, and molecular responses under cold stress have revealed that the cold resistance is more complex than perceived which involves multiple pathways. Like other crops, legumes are also affected by cold stress and therefore, an effective technique to mitigate cold-mediated damage is critical for long-term legume production. Earlier, crop improvement for any stress was challenging for scientific community as conventional breeding approaches like inter-specific or inter-generic hybridization had limited success in crop improvement. The availability of genome sequence, transcriptome, and proteome data provides in-depth sight into different complex mechanisms under cold stress. Identification of QTLs, genes, and proteins responsible for cold stress tolerance will help in improving or developing stress-tolerant legume crop. Cold stress can alter gene expression which further leads to increases in stress protecting metabolites to cope up the plant against the temperature fluctuations. Moreover, genetic engineering can help in development of new cold stress-tolerant varieties of legume crop. This paper provides a general insight into the “omics” approaches for cold stress in legume crops.

Rosa rubiginosa, also called sweet briar, belongs to the group of wild growing roses. Under natural conditions, it prevails throughout Europe, though the species was introduced also to the Southern Hemisphere, where it efficiently adapted to dry lands. This review focuses on the high adaptation potential of sweet briar to soil drought in the context of global climatic changes, especially considering steppe-formation and desertification of agricultural, orchard and horticultural areas. We provide a comprehensive overview of current knowledge on sweet briar traits associated with drought tolerance and particularly: water use efficiency, sugar and CO2 accumulation, stomata conductance, gibberellin level, effective electron transport between PSII and PSI, and accumulation of proteins responsible for photosynthetic fixation of CO2. We discuss the genetics and potential applications in plant breeding and suggest future directions of studies concerning invasive populations of R. rubiginosa. Finally, we point out that sweet briar can provide new genes for breeding in the context of depleting gene pool of the crop plants.
