Several biotic stresses

Protein disulfide isomerase (PDI) and PDI-like proteins contain thioredoxin domains that catalyze protein disulfide bond, inhibit aggregation of misfolded proteins, and function in isomerization during protein folding in endoplasmic reticulum and responses during abiotic stresses.Chinese cabbage is widely recognized as an economically important, nutritious vegetable, but its yield is severely hampered by various biotic and abiotic stresses. Because of, it is prime need to identify those genes whose are responsible for biotic and abiotic stress tolerance. PDI family genes are among of them.

O-methyltransferases (OMTs) are an important group of enzymes that catalyze the transfer of a methyl group from S-adenosyl-L-methionine to their acceptor substrates. OMTs are divided into several groups according to their structural features. In Gossypium species, they are involved in phenolics and flavonoid pathways.

Ethylene Responsive Factor (ERF) is involved in various processes of plant development and stress responses. In wheat, several ERFs have been identified and their roles in mediating biotic or abiotic stresses have been elucidated. However, their effects on wheat plant architecture and yield-related traits remain poorly studied.

The main constraints hampering higher yields and quality of groundnut in Karnataka could be attributed to several production constraints, which may biotic and abiotic stresses include poor and imbalanced nutrition. Therefore, plant nutrition plays a vital role in increasing production and productivity of groundnut. Fertilizer application normally results in increased crop yields up to certain levels. However, the exact time and dose of fertilizer application is also important for successful exploitation of the crop’s potentiality in terms of yield.

Cowpea is an important leguminous vegetable crop usually grown during Pre-kharif, Kharif and Rabi season under West Bengal condition. Now days this crop is severely affected due to biotic stress. Seven foliar pathogens namely Alternaria alternata, Colletotrichum capsici, Corynespora cassicola, Rhizoctonia solani, Fusarium ciceri, Sclerotium rolfsii and Curvularia lunata were isolated from the diseased cowpea crop in Jaguli Instructional farm of BCKV.

Gum is natural biopolymers and formed via process of gummosis due to biotic and abiotic stresses i.e. injury, infection, drought, heat, high temperature, asby product of metabolic pathway and cannot re-enter in the system. Gum karaya (Sterculia urens Roxb.) is a dry deciduous tree belonging to the family Sterculiaceae distributed throughout India and Chhattisgarh. Karaya gum is the dried exudate obtained from trees of Sterculia species. Karaya gum is predominately used for many industries such as petroleum and gas, textiles, paper and pulp, pharmaceuticals, medicine and several other products.

Rapid increase of human population in this changing climate scenario, resulted in increased demand of plant based food and energy sources. Fruits are often referred as “protective food" being rich in vitamins and minerals. However, fruit production is severally impacted by many abiotic and biotic stresses. Because an increase demand exists in global fruit production, therefore many economically important fruit crops are needed to be improved.

Several biotic and abiotic constraints significantly reducing the chickpea area and production over last two decades. Among biotic stresses, fusarium wilt caused by Fusarium oxysporum f. sp. ciceri (Foc) is the major soil-borne fungus affecting chickpea production globally. This Fusarium wilt disease affects chickpea not only quantitatively but also qualitatively. The development of resistant varieties is the most effective method to manage this disease and to stabilizing its productivity.

India is the largest producer and consumer of the pulses in world. There is a huge shortage of pulses in the country to meet out the domestic demand especially of vegetarian population. The low production and productivity of pulses under Indian condition is mainly due to several biotic and abiotic constraints. In general, the pulses crops are more susceptible to the stresses including weeds as compare to the cereals and oilseeds. It was widely reported that yield losses due to weeds especially in the pulses are more than the loss caused either by insect-pest or diseases.

Fruits and vegetables are often referred to as “protective foods” because they are rich in minerals and vitamins. Fruit production is severely impacted by various biotic and abiotic stresses and during the past, efforts have been made by conventional breeding programs to mitigate these problems. However, classical breeding has had little success in improving fruit plants and is constrained due to long juvenile period, genetic erosion, genetic drag and reproductive barriers that limit the transfer of favourable genes from diverse genetic resources.
