... The uncovering of QTLs in such populations leads to high mapping resolution since they harness all historical recombination events [12]. Various characteristics in wheat, including agro-morphological traits [14], resistance to stripe rust [15], stem rust [16], powdery mildew [17], and fusarium head blight [18] have been dissected successfully by association mapping. There are some reports on mapping QTL/genes involved in bread wheat resistance to leaf rust [9,[19][20][21][22][23], with a potential to marker-assisted selection (MAS). ...

... Specifically, the CI effects are quite evident in the plant species from tropical and subtropical climatic zones (Chen et al. 2019). Although the degree of CI damage will greatly vary subject to the plant's innate ability, most of the commercially significant cucurbits such as cucumber (Cabrera et al. 1992;Lukatkin and Anjum 2014;You et al. 2022) and watermelon ) are vulnerable to chilling stress at any stage of their development. Even during crop reaping stages, many cucurbits are harvested before reaching the physiological maturation stage. ...

... Cucumber fruit flesh is typically white; however, variants with yellow, orange, and green flesh are observed (Figure 1e). Yellow and orange flesh result from carotenoid accumulation [142,143], including beta-carotene. As beta-carotene is a precursor of vitamin A, orange flesh is of interest to improve nutritional content. ...

... Bonactin reduced mycelium growth more effectively than feigrisolide C. The authors noted that, to be able to recommend these molecules as fungicides for wheat blight control, the further study of additional M. oryzae isolates is needed to determine their exact mode of action and disease control effectiveness under various field conditions. Next, a literature review, which is more species-specific in its scope, concerns the response to abiotic stress of cultivated beet (Beta vulgaris L.) [15]; this review shows selected aspects of molecular, biochemical, physiological, and structural responses to heavy metals, alkalines, non-optimal temperatures, and UV stresses. Here, attention was also paid to changes in the expression of selected genes that seem to play important roles in response to the abiotic stresses of beet plants. ...

... Compared to leaves produced in vitro, ex-vitro leaves contained higher concentrations of the total carotenoids, lutein, -tocopherol, -carotene, neoxanthin, -carotene, violaxanthin, -linolenic acid, palmitic acid, oleic acid, and palmitoleic acid. These results suggest that ex-vitro grown KP leaves can be an advantageous natural source for extracting necessary lipophilic antioxidants (Song K. et al., 2021). The demand for essential oils of KG has grown both nationally and internationally therefore it is necessary to find a high yielding good quality chemovar. ...

... Several biotic and abiotic stresses such as weeds, diseases, pests, salinity and herbicides negatively affect the quality as well as quantity of beet production (Ma et al. 2020;Yolcu et al. 2021;Das and Pattana yak 2022). A combined approach of conventional and advanced biotechnological methods dramatically changed sugar beet cultivation by identifying novel traits related to various stresses. ...

... Therefore, the phenotypic responses of the lines under different input levels of P might be related to the increase in P uptake when additional P fertilizer was supplied. In a previous study, Pup1 introgression lines in the IR64 background-IR64-Pup1 and IR64-Pup1+Sub1-exhibited more than a two-fold change in shoot P content in the P-supplied content versus the P-non-supplied soil at 48 DAT compared to that of the IR64, [13] which suggests Pup1's benefit when P fertilizer is supplemented. ...

... Plantlets of KP were adapted in a growing chamber for 2 weeks, and 98 per cent of them survived. Additionally, Park et al. claimed that growth was achieved when the surface of rhizome buds was sterilized with silver nanostructures rather than sodium hypochlorite (Park et al., 2021). ...

... In plant hybrids, there is usually a greater expression of the characteristics of the ovule donor over those of the pollen donor [76,77]. This may partly reflect the expression of maternal traits in chloroplasts and mitochondria DNA [78]. Both organelles are usually inherited from maternal parent [78,79]. ...

... Modern biotechnology tools can be used to introduce foreign genes into the genome of an individual 21 , thereby enhancing the genetic variability of the species as the introduced genes are heritable and can OPEN be passed to the progeny. With the importance of genetic variability in a breeding program, germplasm collection, maintenance and regular assessment have been an important part of the activities in research institutions [22][23][24] . The current study concerns the Cucurbita moschata germplasm in Cote d'Ivoire, precisely its morphological characterization as part of a program of Cucurbita moschata improvement. ...
