“…Similar findings were also observed in cotton (Gür et al, 2010), wheat (Sairam et al, 2000) and chickpea (Kaushal et al 2011). Peroxidase activity metabolize hydrogen peroxide into water and oxygen which helps the plant to detoxify reactive oxygen species (Zafar et al, 2020). Peroxidase is one of the primary enzymes that detoxify hydrogen peroxide content inside the cytosol and chloroplasts other plant cells (Farooq, 2019).Carotenoids also increased under stress condition as they are important antioxidants for safeguarding of singlet oxygen (McElroy & Kopsell, 2009).…”

To understand the effect of heat stress on morphology and physiology of the cotton, eight cotton genotypes with their 15F1 hybrids (five lines, three testers) were grown in the field conditions under randomized complete block design (RCBD) with two treatments i.e. normal and hightemperature stresses with two replications followed by split-plot arrangement. Data were collected for biochemical and yield-related parameters. Mean values of all studied traits were reduced significantly under high-temperature stress whilst the mean value of lint%, catalase activity, total soluble proteins, peroxidase, and carotenoids were increased under high-temperature. Under both conditions, the number of bolls, boll weight, seed cotton yield, lint index, seed mass per boll, hydrogen peroxide content, catalase activity, total soluble proteins, carotenoids, and chlorophyll contents had high heritability values along with high genetic advance percent mean which revealed, these traits were controlled by additive gene action. The lint%, seed index, short fiber index, fiber strength, fiber fineness, upper half mean length and peroxidase activity had high heritability with moderate genetic advance under heat stress conditions which showed, these traits were controlled by non-additive gene action. Under both temperature conditions, FH-458, IUB-65, CRS-2, and FH-313 were good general combiners for physicochemical and yield-related traits. The cross combination of IUB-013× CRS-2 and FH-458× FH-313 were good specific combiner for plant height and seed cotton yield whilst for fiber quality and biochemical traits, the best specific combiners were VH-329× FH-313 and IUB-013× CRS-2. These identified parents and cross combinations might be used for improving already present commercial varieties under high-temperature stress.

“…Therefore, the transgenic methodology is now preferred to enhance agronomic traits and has received great success in cotton. The success of Bt cotton for insect resistance ( Zafar et al, 2020 ) is a great example of a transgenic crop. Therefore, determination and genetic alteration of major NUE-efficient genes become a crucial step towards improving cotton NUE.…”

Nitrogen use efficiency in cotton: Challenges and opportunities against environmental constraints

Nitrogen is a vital nutrient for agricultural, and a defieciency of it causes stagnate cotton growth and yield penalty. Farmers rely heavily on N over-application to boost cotton output, which can result in decreased lint yield, quality, and N use efficiency (NUE). Therefore, improving NUE in cotton is most crucial for reducing environmental nitrate pollution and increasing farm profitability. Well-defined management practices, such as the type of sources, N-rate, application time, application method, crop growth stages, and genotypes, have a notable impact on NUE. Different N formulations, such as slow and controlled released fertilizers, have been shown to improve N uptake and, NUE. Increasing N rates are said to boost cotton yield, although high rates may potentially impair the yield depending on the soil and environmental conditions. This study comprehensively reviews various factors including agronomic and environmental constraints that influence N uptake, transport, accumulation, and ultimately NUE in cotton. Furthermore, we explore several agronomic and molecular approaches to enhance efficiency for better N uptake and utilization in cotton. Finally, this objective of this review to highlight a comprehensive view on enhancement of NUE in cotton and could be useful for understanding the physiological, biochemical and molecular mechanism of N in cotton.

“…The negative environmental factors including drought, heat and cold stresses greatly affect the overall production of cotton Zafar et al 2021). The negative environmental factors including cold, salt, drought, heat, fungi, viruses, bacteria, nematodes and insects adversely affect plants' growth, development, productivity and quality (Mammadov et al 2018;Zafar et al 2022a;Zafar et al 2020;Zhu et al 2013). Advanced molecular techniques have been successfully implemented to reveal and understand the mechanism of plant responses and their adaptability to environmental challenges (Zhu 2002).…”

Background: The MBF1 genes are transcription co-activators that trigger the transcription factors activity by bridging TATA-element binding proteins and basic leucine zipper (bZIP) transcription factors in yeast, human and drosophila. MBF1s activate the gene expression in response to plant development, abiotic stresses including heat, cold, salt, drought and biotic stress, including pathogen attack. It also plays a critical role in physiological and biochemical processes, including hormonal regulation, lipid metabolism and cell differentiation. However, MBF1's role in cotton is still unknown. Results: The multiprotein bridging factor1 (MBF1) genes are being characterized for the first time in four cotton genomes. A total of 24 MBF1 genes were identified in four cotton genomes, including 8 genes in G. hirsutum (GhMBF01-GhMBF08), 8 in genes G. barbadense (GbMBF01-GbMBF08), 4 genes in G. arboreum (GaMBF01-GaMBF04) and 4 in G. raimondii (GrMBF01-GrMBF04) respectively. Phylogenetic relationship analysis in 11 plant species suggested the classification of MBF1 genes into two major groups that suggested evolutionary uniqueness in both groups. Comparative analyses of structural features, motif conservation, cis-regulatory elements, genes enrichment and protein-protein interaction network suggested distinctive characteristics, functions and their relation with biologically functional genes. A comparative transcriptome analysis proposed the role of MBF1 genes in plant growth, response to abiotic and biotic stress tolerance, seed germination and cotton fiber development. The qRT-PCR validation of GhMBF02 (GH_A04G0454, Type b), GhMBF04 (GH_A08G2678, Type b), GhMBF07 (GH_D06G0632, Type C), and GhMBF08 (GH_D08G2673, Type b) suggested a positive role of MBF1 in fiber elongation stages of fiber quality specific RIL population lines. Conclusion: Present study introduced and provided useful information about the potential of MBF1 family genes in response to various growth and developmental stages, biotic and abiotic stresses in cotton that can be referred for further function-based experiments.
