Abiotic Stress Tolerance in Cotton

Abstract

Cotton (Gossypium hirsutum L.) is a vital fiber crop that is being cultivated under diverse climatic conditions across the globe. The demand for cotton and its by-products is increasing day by day due to more consumption of this fiber in the textile industry and the utilization of cotton seed as a source of edible oil. However, the average seed cotton yield in the world is below that of the potential yield of cultivars. The factors responsible for low yield includes shortage of approved seed, pest and disease attack, weed infestation, unwise use of nutrients, and the incidence of abiotic stresses (including drought, heat, and salinity). Among these, the abiotic stresses are a single major factor, which is responsible for reducing the yield now and will affect the productivity of cotton in future. In this scenario, it is necessary to adopt ways to improve the tolerance of cotton against abiotic stresses. The strategies for improving tolerance against abiotic stresses may include the wise use of macroand micronutrients, the use of osmoprotectants, the use of arbuscular mycorrhizal fungi, and the plant-growth promoting rhizobacteria.

Complications of Ilizarov method treatment for infected nonunion femoral shaft fracture

“…Likewise in the studies of Hassan et al and Kanagasarathy et al right-sided involvement was 80% and 63% respectively. 10,15 Among the 40 patients, 16 (40%) were closed fractures and 24 (60%) were open fractures initially. Among the open fractures, 16 (40%) were Gustilo IIIA (10%) were Gustilo II and 4 (10%) were Gustilo IIIB.…”

“…The Ilizarov ring fixator can be used for mono-focal or bifocal compression distraction and bone segment transport depending upon the bone defect at the site of nonunion. 1,10 The regeneration of new bone to fill the defect is distraction osteogenesis and is based upon the "Theory of tension stress" introduced by Gavriil Abramovich Ilizarov in 1951. 8 The control of infection is achieved by radical debridement of the bone ends.…”

“…4 The regeneration of new bone not only covers the bone defect but also eliminates infection as claimed by Ilizarov that "Osteomyelitis burns in the flame of regenerate". 10 Amputation is one of the hazards of infected non-union and so the Ilizarov method can minimize this potential outcome. 11 Up to now, there have been several reports on the treatment of infected non-union of the femur by Ilizarov methods, and it has progressively been the key treatment for infected non-union.…”

Transgenerational impact of climatic changes on cotton production

“…These stresses have become a major obstacle to achieving cotton yield potential by disrupting various morphological, physiological, and metabolic processes (Hassan et al, 2020). The development of high yield cultivars tailored according to changing climatic conditions has become inevitable to sustain the high yield of the cotton crop (Wang et al, 2013).…”

Establishment and Application of a Monitoring Strategy for Living Modified Cotton in Natural Environments in South Korea

“…LM cotton is one of the major LM crops, along with soybean, maize, and canola. Cotton production is vulnerable to biotic stresses such as insect attacks and abiotic factors such as temperature, drought, and salinity [3][4][5][6][7]. LM crops are widely used in agriculture to improve crop quality by introducing new traits, including insect resistance, herbicide tolerance, higher yields, and resistance to abiotic and biotic stresses [8][9][10].…”
