“…The ability of CAT to reduce oxidative damage is demonstrated by the fact that the better the CAT activity in plants, the lower the H2O2 rise ratio. The impact of H2O2 pretreatment on maize leaves was investigated by (Bakala et al, 2023). The highest initial activity and the strongest response to H2O2 were displayed by CAT, showing the role it plays in plants' ROS scavenging (Jiang et al, 2023).…”

The production of plants and crops is inﬂuenced by environmental stress, which is a serious scientific issue. Cotton is an essential crop for producing natural fibers that are used to make biofuel and edible oils. Salinity is the main element that influences cotton growth during the beginning of germination. The type of salt and the growth stage affects how sensitive a plant is to salt stress. Developing ways to enhance cotton performance in salty circumstances can be aided by an understanding of the response of cotton to salt, its mechanism of resistance, and its management methods. Osmotic and ionic imbalances originate due to the deposition of soluble salts under salinity stress in the plant's root zone. Soil salinity significantly reduces plant growth due to several factors, such as nutritional ion imbalance, which reduces K+, PO4-, and NO- absorption, excessive salt chloride concentrations, and osmotic stress, which hinders water availability. Research has revealed that compared to subsequent stages, the germination, emergence, and seedling phases are more vulnerable to salinity stress, which ultimately affects the seed cotton yield by delaying blooming, reducing fruiting positions, shedding fewer fruits, and reducing boll weight. The morphology, growth of cotton roots, shoots, yield, and fiber quality are all strongly impacted by salinity stress. It slows down plant feeding, cellular metabolism, and photosynthesis. The soil, water, and climate all affect how the plant responds to salinity stress. During salt stress, excessive exclusion of sodium or its compartmentalization is the key adaptation process in cotton. A major adaptive potential to create cotton types that can withstand salt is provided by the up-regulation of both physicochemical and non-enzymatic antioxidant genes. A successful strategy to increase cotton germination in saline soils is seed priming. Moreover, the transgenic strategy might be a viable choice for improving cotton yield in saline environments. Our review focuses on the impacts of salinity on cotton productivity as well as how plants react to salt stress. It also clarifies recent genetic advancements and molecular breeding for cotton's resistance to soil salt. To create salt-tolerant cultivars, a combination of traditional breeding and novel molecular approaches will be useful.

“…The global acreage of maize is around 203 × 10 6 hectares, which produces approximately 1163 × 10 6 tons of grains [1]. In many countries, maize is an important source of national income [5,6]. With its growing population and increasing demand for maize, Egypt faces a notable production-consumption gap of around nine million tons annually [1].…”

Nitrogen is an essential element for maize growth, but excessive application can lead to various environmental and ecological issues, including water pollution, air pollution, greenhouse gas emissions, and biodiversity loss. Hence, developing maize hybrids resilient to low-N conditions is vital for sustainable agriculture, particularly in nitrogen-deficient soils. Combining ability and genetic relationships among parental lines is crucial for breeding superior hybrids under diverse nitrogen levels. This study aimed to assess the genetic diversity of maize inbred lines using simple sequence repeat (SSR) markers and evaluate their combining ability to identify superior hybrids under low-N and recommended conditions. Local and exotic inbred lines were genotyped using SSR markers, revealing substantial genetic variation with high gene diversity (He = 0.60), moderate polymorphism information content (PIC = 0.54), and an average of 3.64 alleles per locus. Twenty-one F1 hybrids were generated through a diallel mating design using these diverse lines. These hybrids and a high yielding commercial check (SC-131) were field-tested under low-N and recommended N conditions. Significant variations (p < 0.01) were observed among nitrogen levels, hybrids, and their interaction for all recorded traits. Additive genetic variances predominated over non-additive genetic variances for grain yield and most traits. Inbred IL3 emerged as an effective combiner for developing early maturing genotypes with lower ear placement. Additionally, inbreds IL1, IL2, and IL3 showed promise as superior combiners for enhancing grain yield and related traits under both low-N and recommended conditions. Notably, hybrids IL1×IL4, IL2×IL5, IL2×IL6, and IL5×IL7 exhibited specific combining abilities for increasing grain yield and associated traits under low-N stress conditions. Furthermore, strong positive associations were identified between grain yield and specific traits like plant height, ear length, number of rows per ear, and number of kernels per row. Due to their straightforward measurability, these relationships underscore the potential of using these traits as proxies for indirect selection in early breeding generations, particularly under low-N stress. This research contributes to breeding nitrogen-efficient maize hybrids and advances our understanding of the genetic foundations for tolerance to nitrogen limitations.

The emission of greenhouse gases, particularly carbon dioxide, predominantly from fossil fuel combustion has received critical warnings several times as their levels exceed the tolerable limits in view of global warming. This calls for a paradigm shift from a fossil fuel‐based source to a less hazardous bioenergy source. Plant feedstock is an attractive source of raw materials for bioenergy production; however, chemical or enzymatic digestion of the feedstock is expensive owing to the supramolecular lignocellulosic barrier, indicating the need for better alternatives. Several attempts have been made towards reducing the biomass recalcitrance of straw using genetic transformations. We present a review highlighting potential plant candidates for bioenergy production, the lignocellulose composition of the feedstock, how the composition can impede enzymatic degradation, the regulation of lignocellulose polymer biosynthesis, and the influence of genetic transformation on biomass saccharification. Moreover, the review also discusses conflicting research interests in biomass recalcitrance and suggests a common ground. The review findings suggest that bioenergy production from crop straws will drastically reduce over‐dependence on fossil fuels and consequently pollution levels.
