“…Decreased desaturation degree of fatty acids and galactolipids as well as increased phospholipid content provide a membrane stability under drought [89, 90]. Conversion of stearic acid into polyunsaturated fatty acids under drought was noticed in fenugreek ( Trigonella foenum - graecum L.) genotypes [91]. However, there is a limited number of studies which demonstrate a connection between composition and saturation degree of specific fatty acid and membrane damage under water deficit.…”

Wheat is one of the most important cereals, whose growth and development is strongly limited by drought. This study investigated the physiological and metabolic response of six winter wheat cultivars to drought with the emphasis on the induction of dominant metabolites affected by the treatment and genotypes or both. The plants were exposed to a moderate (non-lethal) drought stress, which was induced by withholding watering for six days under controlled greenhouse conditions. A decline in CO 2 assimilation (Pn) and transpiration rate, stomata closure, a decrease in relative water content (RWC) and increase of malondialdehyde content were observed in drought-treated plants of all cultivars. These changes were most pronounced in Ellvis, while Soissons was able to retain the higher RWC and Pn. Among the studied metabolites, sugars (sucrose, glucose, fructose, several disaccharides), organic acids (malic acid, oxalic acids), amino acids (proline, threonine, gamma-aminobutyric acid (GABA), glutamine) and sugar alcohols such as myo-inositol accumulated to higher levels in the plants exposed to drought stress in comparison with the control. The accumulation of several metabolites in response to drought differed between the genotypes. Drought induced the production of sucrose, malic acid and oxalic acid, unknown organic acid 1, unknown disaccharide 1, 2 and 3, GABA, L-threonine, glutamic acid in four (Soissons, Žitarka, Antonija or Toborzó) out of six genotypes. In addition, Soissons, which was the most drought tolerant genotype, accumulated the highest amount of unknown disaccharide 5, galactonic and phosphoric acids. The two most drought sensitive cultivars, Srpanjka and Ellvis, demonstrated different metabolic adjustment in response to the stress treatment. Srpanjka responded to drought by increasing the amount of glucose and fructose originated from hydrolyses of sucrose and accumulating unidentified sugar alcohols 1 and 2. In Ellvis, drought caused inhibition of photosynthetic carbon metabolism, as evidence by the decreased Pn, gs, RWC and accumulation levels of sugar metabolites (sucrose, glucose and fructose). The results revealed the differences in metabolic response to drought among the genotypes, which drew attention on metabolites related with general response and on those metabolites which are part of specific response that may play an important role in drought tolerance.

“…On the other hand, Trigonella corniculata is an annual, slow-growing, bushy herb with rosette-like vegetative growth, producing bright orange to yellow flowers and sickle-shaped pods with small-sized and scented seeds ( Yadav et al, 2021 ). Kasuri methi, also known as “Champa methi” or “Marwari methi,” is cultivated as a semi-arid crop during the rabi (spring) season and is recognized for its tolerance to drought and frost, requiring cool and dry weather for maturity ( Saxena et al, 2017 ). The Pusa kasuri variety is a small-seeded type, mainly cultivated for leaf purposes and not for seeds.…”

Plant breeding, aimed at enhancing desired traits, depends on genetic diversity. Mutation breeding is a powerful method of rapidly expanding genetic diversity, facilitating crop improvement, and ensuring food security. In a recent study, researchers evaluated the genetic variability of Trigonella species using different doses of sodium azide (SA) (0.2%, 0.4%, 0.6%, 0.8%, and 1.0%) through morphological, physiological, and cytogenetic studies. Morphological variations were observed in cotyledonary leaves, vegetative leaves, and overall plant growth and habit. Several quantitative parameters, such as plant height, fertile branches per plant, pods per plant (or clusters), seeds per pod, and seed yield, increased when treated with 0.2% and 0.4% SA compared to the control. Furthermore, the total chlorophyll content and carotenoids increased in the sample treated with 0.2% SA over the control but decreased with higher concentrations. Scanning electron microscopy revealed that stomatal aperture and seed dimensions increased at lower concentrations of sodium azide treatment. The study found a positive correlation between the different parameters studied in the Trigonella species, as indicated by high r-values. Based on their findings, it was concluded that the genotype of fenugreek can be improved by using 0.2% and 0.4% concentrations of sodium azide. However, the evaluation of observed variants in successive generations is a critical and necessary process to validate their potential as keystones for crop genetic improvements.

“…The use of genetic diversity to obtain a sustainable yield in dryland conditions with water deficiency is a well-practiced crop development strategy [19]. Many previous studies on fenugreek have been carried out on different-origin genotypes or local cultivars.…”

In this study, 18 fenugreek genotypes and two cultivars were cultivated under irrigated and dryland conditions to determine the morphological, yield, quality, and bioactive properties. The morphological and seed yield values showed differences among the fenugreek genotypes and cultivars. The PI 286532 and PI 639185 genotypes for total alkaloid content and the PI 426973 and PI 572538 genotypes for trigonelline content were prominent under both irrigated and dryland conditions. The PI 215615 and PI 286532 genotypes were found to be rich in fixed oil contents under two growing conditions, while all fenugreek genotypes had high linoleic contents. The PI 568215 and PI 251640 genotypes and the gürarslan cultivar had the highest antioxidant activity compared with the other genotypes. The PI 215615 and PI 302448 genotypes and the gürarslan cultivar were found to be superior with respect to phenolic and flavonoid contents. Generally, the cluster analysis clustered the genotypes into two main groups and two sub-groups. Group B included more than 66% of the genotypes and cultivars. The biplot analysis accounted for over 53% of total variations. As a result of this study, most of the genotypes were found to be high in the examined properties, and these genotypes were good sources of natural components with potential applications in the food and pharmaceutical industries.
