“…The results indicated that the tolerance mechanism of wheat seedlings primed with moringa leaf extract compartmentalizes the Na ions and restricts their uptake more efficiently as compared to the seeds primed with water. Khalid et al (2020) also reported that restricted accumulation of toxic ions enhances the accumulation of other minerals, which maintains the plant metabolism and anchors the plant to fight more efficiently against salt stress [7]. The accumulation of toxic ions causes an imbalance in the plant nutrients, which affects its physiological attributes and production of different reactive oxygen species (ROS) [16].…”

“…Hydropriming allows the seeds to swiftly attain a sufficient amount of water and constant oxygen, which enhances germination by overcoming germination barriers specifically under unfavorable conditions, i.e., salinity, drought, etc. [7]. In hydropriming, different priming agents were used (i.e., salicylic acid, gibberellic acid, etc.…”

Salinity is the major constraint that decreases the yield and production of crops. Wheat has a significant value in agricultural food commodities. The germination and growth of wheat seedlings are a big challenge in salt-affected soils. The seed priming technique is used to mitigate salt stress and enhance the germination and growth of the crops. Therefore, the current study was conducted to evaluate the hydropriming of natural plant extract (moringa leaf extract) and water on wheat seeds and grown under different saline (0, 0.05, 0.1, 0.15, and 0.2 M NaCl) environments. The germination attributes (germination percentage, germination index, mean germination day, coefficient of variance, vigor index) and seedling growth (fresh weight, dry weight, root length, shoot length) were enhanced in the plants primed by moringa leaf extract. The germination percentage was observed 10% more at 0.2 M NaCl stress in seeds treated with moringa leaf extract than seeds treated with water. The nutrient (K, Ca, Mg, P, S, Fe, B, Mn, Zn, Cu) uptake was also observed more in the shoots and roots of wheat seedlings soaked in moringa leaf extract as compared to soaked in water. Controlled plants showed higher concentrations of toxic ions (Na) and reactive oxygen species (H2O2) in shoots and roots of wheat seedlings. The use of moringa leaf extract for priming wheat seeds will enhance their germination and growth by maintaining efficient nutrient uptake and restricting the toxic ions and reactive oxygen species accumulation.

“…Polyploidization has shown tremendous scope in the investigation of inheritance patterns in plants as they show higher heterozygosity. In addition, polyploids are more tolerant to stressful environmental conditions and have less inbreeding depression than their diploid progenitors [121]. Polyploidy has been observed in different plants and, in citrus, it was reported that temperature stress, bud pollination, and chromosome doubling can influence polyploidy [122].…”

Citrus, belonging to the Rutaceae family, is a commercial fruit worldwide, and it is mainly recognized for its nutritional, anti-oxidant, and significant medicinal properties. Citruses are a group of multifaceted fruit crops with a rich traditional knowledge, deeply rooted in ethnic culture, and the fruits have been considered to be health-protecting and health-promoting food supplements since ancient times. The presence of secondary metabolites and their bioactivities has led to the development of new alternative drugs in recent years. Diverse secondary metabolites such as flavonoids, alkaloids, carotenoids, phenolic acids, and essential oils and their high bioactive properties have imparted great value to human health based on their anti-oxidative, anti-inflammatory, anti-cancer, cardiovascular protective, and neuroprotective effects. The indigenous Citrus species of India—mainly Northeast India—have distinctive and valuable genetic traits, such as resistance to biotic and abiotic stress, distinctive aroma, flavor, etc. Hence, these species are considered to be repertoires of valuable genes for molecular breeding aimed at quality improvement. There is a need for awareness and understanding among the citrus-producing countries of the exploitation of biodiversity and the conservation of Citrus for sustainable development and bioprospecting. The current review presents a holistic view of Citrus biodiversity from a global perspective, including phytochemical constituents and health benefits. Advanced biotechnological and genomic approaches for Citrus trait improvement have also been discussed to highlight their relevance in Citrus improvement.
