MicroRNAs (miRNAs) are a class of non-coding single-stranded RNA molecules composed of approximately 20–24 nucleotides in plants. They play an important regulatory role in plant growth and development and as a signal in abiotic tolerance. Some abiotic stresses include drought, salt, cold, high temperature, heavy metals and nutritional elements. miRNAs affect gene expression by manipulating the cleavage, translational expression or DNA methylation of target messenger RNAs (mRNAs). This review describes the current progress in the field considering two aspects: (i) the way miRNAs are produced and regulated and (ii) the way miRNA/target genes are used in plant responses to various abiotic stresses. Studying the molecular mechanism of action of miRNAs’ downstream target genes could optimize the genetic manipulation of crop growth and development conditions to provide a more theoretically optimized basis for improving crop production. MicroRNA is a novel signalling mechanism in interplant communication relating to abiotic tolerance.

“…is one of the most economically viable crops, with a global utilization. It provides fine lint for the textile industry, feedstock for bioenergy production, and seeds with several nutritional attributes for oil and feed production (Ninkuu et al, 2023; Viot & Wendel, 2023; Yuan et al, 2018). Global cottonseed production in 2022 was 35.76 million metric tons, with production in 2023 estimated to be 42.11 million metric tons (Shahbandeh, 2022a).…”

Societal Impact StatementGossypol and its derivatives represent a class of toxic and immunosuppressive compounds that are naturally synthesized in cottonseed. These compounds pose several health hazards to humans and animals, such as heart and lung damage, breathing difficulties, and death in swine. In poultry, gossypol reduces egg production and slows growth. Studies have also shown that gossypol can indirectly harm humans and animals through the food chain. Although several physical and chemical approaches are adopted to reduce gossypol levels in cottonseed before food and feed processing, these techniques are expensive. Therefore, genetically regulating gossypol production in cotton could provide a cheaper alternative.SummaryCotton (Gossypium spp.), the most important fiber crop, is cultivated in over a hundred countries to provide raw materials for the growing textile industry. The seed obtained after delinting cotton is a rich source of protein with a vast potential for oil and feed production. Cottonseed oil production is estimated at 5.08 million metric tons and is expected to generate over 6.56 billion United States Dollars in revenue by 2029. The cake from defatted cottonseed is used as animal feed and food supplements. However, the contamination of gossypol in cottonseed limits its use. Gossypol ingestion impairs weight gain and causes anorexia, respiratory distress, and death under extreme exposure. This review highlights the significance of cottonseed oil and meal; the pharmacological uses and impact of gossypol; the chemistry, toxicity, and bioactivity of gossypol; and the physical and chemical methods used in gossypol removal during feed and food supplement processing. In addition, the biosynthetic pathway of gossypol and attempts to genetically transform some key regulators of this pathway to produce glandless cottonseed or reduce the gossypol levels in the seed are discussed.

“…Ammonium (NH 4 + ) is a predominant form of nitrogen (N) that supports plant growth, especially when furnished with an adequate amount of nitrate (NO 3 - ) ( Dubey et al., 2021 ; Vu et al., 2021 ; Zhu et al., 2021 ; Ninkuu et al., 2023 ). Compared to sole NO 3 - or NH 4 + , crop growth and yield peaks when NH 4 + and NO 3 - are appropriately combined in growth medium ( Liang et al., 2022 ; Saloner and Bernstein, 2022 ; Xiao et al., 2023 ).…”

Inherently, ammonium (NH4+) is critical for plant growth; however, its toxicity suppresses potassium (K+) uptake and vice-versa. Hence, attaining a nutritional balance between these two ions (NH4+ and K+) becomes imperative for the growth of tobacco seedlings. Therefore, we conducted a 15-day experimental study on tobacco seedlings exposed to different concentrations (47 treatments) of NH4+/K+ at different corresponding 12 ratios simultaneously in a hydroponic system. Our study aimed at establishing the optimal NH4+-K+ concentration and the corresponding ratio required for optimal growth of different tobacco plant organs during the seedling stage. The controls were the baseline for comparison in this study. Plants with low or excessive NH4+-K+ concentration had leaf chlorosis or dark greenish colouration, stunted whole plant part biomass, and thin roots. We found that adequate K+ supply is a pragmatic way to mitigate NH4+-induced toxicity in tobacco plants. The optimal growth for tobacco leaf and root was attained at NH4+-K+ concentrations 2-2 mM (ratio 1:1), whereas stem growth was optimal at NH4+-K+ 1-2 mM (1:2). The study provided an insight into the right combination of NH4+/K+ that could mitigate or prevent NH4+ or K+ stress in the tobacco seedlings.
