“…Greaves and Wang, (2017) concluded that long drought cycles on corn attributed to lower rainfall. Similar results emphasized the negative effect of drought on the growth of corn reported Randhawa et al (2017). Corn is sensitive to moisture stress during vegetative growth and tasselling stages (Anandhi, 2016).…”

The beta casein gene (CSNS2) has 12 genetic variants divided into two groups: the first group (A1, B, and G) which differ from the second group (A2, A3 C, D, E, F, H, H2 and I) where A base replaces C base, this leads to potential liberation of a bioactive peptide, b-casomorphin, upon digestion where a histidine replaces a proline at position 67. The allele specific polymerase chain reaction (AS-PCR) was evaluated to distinguish between the beta casomorphin releasing variants (A1 and B) and the non-releasing variants. The sequence analysis was used to determine these variants and confirm it in goat, sheep and cattle. The results showed that cattle carrying allele A1 either homozygous or heterozygous more than sheep and goats. The allele frequency of A1 and A2 is 0.44, 0.56 in goats, 0.43, 0.57 in sheep and 0.54, 0.46 in cattle, respectively. The sequence results reported changing of C base to A base in goat, sheep and cattle. Therefore, this study reported that goat and sheep milk was more safe than cattle milk.

“…Reduced performance of these physiological parameters results due to moderate to severe water stress during cane growth and development [16]. Reduced relative water content, more negative leaf osmotic potential, and loss in turgor potential are the chief restrictions reflected in cane growth for resistance against water deficit [17][18][19]. Free proline accumulation in the leaves and roots is a response of the plant to avoid celllevel injuries due to severe drought by assisting and stabilizing the membrane, making osmotic adjustments and scavenging oxygen radicals [16].…”

Stumpy irrigation water availability is extremely important for sugarcane production in Pakistan today. This issue is rising inversely to river flow due to inadequate water distribution and an uneven rainfall pattern. Sugarcane growth faces a shortage of available water for plant uptake due to the low water–holding capacity of sandy loam soil, particularly under conventional flood irrigation methods. To address this problem, sugarcane clones were evaluated for their agronomic and physiological traits under conditions of low water availability in sandy loam soil. Ten cane genotypes, HSF–240, SPF–213, CPF–249, CP 77–400, S2008–FD–19, S2006–US–469, S2007–AUS–384, S2003–US–633, S2003–US–127, and S2006–US–658, were exposed to four levels of water deficit created through skip irrigations. These deficit levels occurred during the 9th, 11th, 13th, and 16th irrigations at alternate deficit levels between 2020 and 2022. Physiological data were collected during the tillering and grand growth stages (elongation) in response to the water deficit. The sugarcane clones S2006–US–658, S2007–AUS–384, and HSF–240 exhibited resistance to low water availability at both the tillering and grand growth stages. Following them, genotypes S2006–US–658, S2007–AUS–384, and HSF–240 performed better and were also found to be statistically significant. Clones susceptible to water deficit in terms of growth and development were identified as CP 77–400, S2008–FD–19, S2006–US–469, and S2003–US–633. These genotypes showed reduced photosynthetic rate, transpiration rate, stomatal conductance, relative water content, cane yield, and proline content under stressed conditions. Therefore, genotypes S2006–US–658, S2007–AUS–384, and HSF–240 were better performers concerning physiological traits under water deficit and sandy loam soil in both years. Moreover, a significant positive correlation was assessed between agronomic traits and photosynthetic rats. This study highlights that sugarcane can sustain its growth and development even with less irrigation frequency or moisture availability, albeit with certain specific variations.

“…Drought restricts various crucial physiological processes, including growth performance, correlations between nutrients and water, photosynthesis, and assimilate partitioning, which consequently results in signiﬁcant reductions in biomass production and yield ( Daryanto et al , 2017 ; Hussain et al , 2018 ). A lower absorption rate of photosynthetically active radiation, a decreased radiation use efficiency, and a decline in the harvest index are leading factors of yield reduction under limited soil moisture conditions ( Earl and Davis, 2003 ; Randhawa et al , 2017 ). Evolution has shaped the inherent potential of plant populations for morphological and physiological adjustments that mitigate the detrimental impacts of drought stress ( Farooq et al , 2009 ; Basu et al , 2016 ).…”

Cereals are important crops worldwide that help meet food demands and nutritional needs. In recent years, cereal production has been challenged globally by frequent droughts and hot spells. A plant’s root is the most relevant organ during drought-stress adaptation, playing pivotal roles in anchorage and the acquisition of soil-based resources. Thus, dissecting root system variations and trait selection for enhancing yield and sustainability under drought-stress conditions should aid in future global food security. This review highlights the variations in root system attributes and their interplay with shoot architectural features for the yield and drought-stress adaptation of major cereal crops as determined by quantitative genetics and genomics approaches. Further, we compile the root-related drought-responsive quantitative trait loci (QTL)/genes in cereal crops including their inter-species comparisons using microsynteny to facilitate comparative genomic analyses. We then discuss the potential of an integrated strategy combining genomics and phenomics at genetic and epigenetic levels to explore natural genetic diversity as basis for knowledge-based genome editing. Finally, we present an outline to establish innovative breeding leads for the rapid and optimized selection of root traits necessary to develop resilient crop varieties.
