“…The capacity of plants to retain water during desiccation is an important tactic for plant tolerance to stress brought on by water deprivation stress (Mukami et al, 2019). In an effort to develop cultivars that can withstand drought, the inherent tolerance mechanism in agricultural plants has been researched (Tripathi et al, 2022).…”

“…Proline was extracted and estimated by the colorimetric method (Bates et al, 1973 andTripathi et al, 2022) with some modifications, where level of proline was expressed in μmol proline/g dry weight, 0.25 g of dry leaves were ground and homogenized in 10 ml of 3% sulfosalicylic acid and centrifuged for 15 min at 10,000 rpm, the extract was filtered with Whatman filter paper. The reaction mixtures in the test tubes were vigorously shaken and contain (2 ml of the filtrate, 2 ml of the ninhydrin reagent, and 2 ml of glacial acetic acid) and vigorously shacked.…”

Egypt which has a long-life cycle and a high-water requirement in general. Sugarcane production and growth are negatively impacted by water constraint, especially during the key water requirement period. This study compared nine sugarcane genotypes to the commercial genotype GT.54-9 (Saccharum spp.) in terms of cane yield, sugar yield, and juice quality related to physio-biochemical attributes including chlorophyll (Chl) Soil Plant Analysis Development (SPAD index), Relative Water Content (RWC), and proline content as a biochemical constituent. Under three levels of drought stress (87.5, 75, and 62.5% of reference crop evapotranspiration (ET0), 2 Way Randomized Complete Block Design (RCBD) with two factors and three replications was used in this study. In the severe water scarcity situations (62.5% of ET0). The results showed that the most promising genotypes (G.2004-27 and G.99-103) had good values for the investigated parameters. The work adds to our knowledge of genotype-screening for drought resistance as an effective technique for choosing materials for advanced breeding programs, especially in controlled drought environments. More genomic and molecular research is required to comprehend the precise processes behind sugarcane drought resilience.

“…The ability to recover after severe DS is called drought recovery ( Fang and Xiong, 2015 ; Giordano et al, 2021 ; Sun et al, 2021 ). Hence, DT is a complex polygenic trait, and it is essential to understand the factors behind it ( Tripathi et al, 2022 ). Different genes are activated under DS and control different pathways to protect plants from detrimental effects.…”

Ramie is one of the most significant fiber crops and contributes to good quality fiber. Drought stress (DS) is one of the most devastating abiotic factors which is accountable for a substantial loss in crop growth and production and disturbing sustainable crop production. DS impairs growth, plant water relation, and nutrient uptake. Ramie has evolved a series of defense responses to cope with DS. There are numerous genes regulating the drought tolerance (DT) mechanism in ramie. The morphological and physiological mechanism of DT is well-studied; however, modified methods would be more effective. The use of novel genome editing tools like clustered regularly interspaced short palindromic repeats (CRISPR) is being used to edit the recessive genes in crops to modify their function. The transgenic approaches are used to develop several drought-tolerant varieties in ramie, and further identification of tolerant genes is needed for an effective breeding plan. Quantitative trait loci (QTLs) mapping, transcription factors (TFs) and speed breeding are highly studied techniques, and these would lead to the development of drought-resilient ramie cultivars. The use of hormones in enhancing crop growth and development under water scarcity circumstances is critical; however, using different concentrations and testing genotypes in changing environments would be helpful to sort the tolerant genotypes. Since plants use various ways to counter DS, investigating mechanisms of DT in plants will lead to improved DT in ramie. This critical review summarized the recent advancements on DT in ramie using novel molecular techniques. This information would help ramie breeders to conduct research studies and develop drought tolerant ramie cultivars.

“…Sugarcane ( Saccharum spp. Hybrids), of the Poaceae family, is cultivated in tropical and subtropical areas around the world [ 1 , 2 ]. The economic importance of this species derives from its multiple products, co-products, and by-products, which are used in the food, energy, chemical, and pharmaceutical industries [ 3 , 4 ].…”

The symbiotic associations between arbuscular mycorrhizal fungi (AMF) and plants can induce drought stress tolerance. In this study, we evaluated the effect of Glomus intraradices, a mycorrhizal fungus, on the ex vitro development and survival of sugarcane plantlets subjected to drought stress during the acclimatization stage of micropropagation. In vitro obtained sugarcane plantlets (Saccharum spp. cv Mex 69–290) were inoculated with different doses of G. intraradices (0, 100, and 200 spores per plantlet) during greenhouse acclimatization. Sixty days after inoculation, plantlets were temporarily subjected to drought stress. We evaluated the survival rate, total chlorophyll, total protein, carotenoids, proline, betaine glycine, soluble phenolic content, and antioxidant capacity every 3 days for 12 days. Symbiotic interaction was characterized by microscopy. Our results showed that the survival rate of inoculated plants was higher in 45% than the treatment without mycorrhizae. Total chlorophyll, protein, proline, betaine glycine content, and antioxidant capacity were increased in AMF inoculated plants. The soluble phenolic content was higher in non-inoculated plants than the treatment with mycorrhizae during the drought stress period. Microscopy showed the symbiotic relationship between plant and AMF. The early inoculation of 100 spores of G. intraradices per sugarcane plantlet during the acclimatization stage could represent a preconditioning advantage before transplanting into the field and establishing basic seedbeds.
