“…Green flesh (gf ) was mapped to chromosome 9 [226,227], and white flesh (wf ) was mapped to chromosome 8 [227]. QTLs for carotene content are colocated with these loci [228]. Recently, the green flesh locus has been identified as the CmOr gene, which regulates βcarotene accumulation in orange-fleshed fruit, but not at the carotenoids' biosynthesis level [229].…”

Genetic and Pre- and Postharvest Factors Influencing the Content of Antioxidants in Cucurbit Crops

Cucurbitaceae is one of the most economically important plant families, and includes some worldwide cultivated species like cucumber, melons, and squashes, and some regionally cultivated and feral species that contribute to the human diet. For centuries, cucurbits have been appreciated because of their nutritional value and, in traditional medicine, because of their ability to alleviate certain ailments. Several studies have demonstrated the remarkable contents of valuable compounds in cucurbits, including antioxidants such as polyphenols, flavonoids, and carotenoids, but also tannins and terpenoids, which are abundant. This antioxidant power is beneficial for human health, but also in facing plant diseases and abiotic stresses. This review brings together data on the antioxidant properties of cucurbit species, addressing the genetic and pre- and postharvest factors that regulate the antioxidant content in different plant organs. Environmental conditions, management, storage, and pre- and postharvest treatments influencing the biosynthesis and activity of antioxidants, together with the biodiversity of this family, are determinant in improving the antioxidant potential of this group of species. Plant breeding, as well as the development of innovative biotechnological approaches, is also leading to new possibilities for exploiting cucurbits as functional products.

“…Attempts to map genes controlling economically important traits in cucurbits have focused mainly on C. melo, because of its economic importance. Gonzalo and Montforte (2017) evaluated discrepancies between results published by Yuste-Lisbona et al (2011), Perchepied et al (2005, and Fukino et al (2008) and summarized recent achievements: three major genes/ quantitative trait loci (QTLs) involved in CPM resistance in C. melo have been mapped on chromosomes 2, 5, and 12. Morphological characteristics of powdery mildew from cucumber crops collected in Mexico, together with their sequenced PCRamplified fragments, matched with those described for physiological races 1, 2F, 4, and 5 of Px (Bojórquez-Ramos et al, 2012).…”

Understanding pathogen population structure and virulence variation for efficient resistance breeding to control cucurbit powdery mildews

et al. 2021

Cucurbit powdery mildew (CPM) is caused most frequently by well-differentiated obligate erysiphaceous ectoparasites Golovinomyces orontii and Podosphaera xanthii, which vary in their ecology and virulence. All economically important cucurbit crops host both of these CPM species. Breeding of cucurbits for CPM resistance is highly important worldwide, but adequate knowledge of CPM species determination, as well as virulence structure, population dynamics, and spatiotemporal variation of these pathogens, has not yet been achieved. New tools have been developed to enhance research on CPM virulence variation for more efficient breeding and seed and crop production. A set of differential genotypes of Cucumis melo, with high differentiation capacity, may contribute substantially to understanding of variation in CPM virulence at both individual and population levels. Long-term observations (2001-2012) of CPM pathogens in the Czech Republic were used to analyse virulence variation within and among annual CPM populations and demonstrate the utility of recently developed tools for studying species variability and virulence variation of CPM pathogens worldwide. Detailed analyses of diversity and spatiotemporal fluctuations in the composition of CPM populations provide crucial information for shaping breeding programmes and predicting the most effective sources of race-specific resistance. The primary aim of this work was to create a uniform framework for determination of CPM species structure and diversity, virulence phenotypes, virulence and phenotype frequencies, phenotype complexity, dynamics, and variation within and among CPM populations.

“…FW is correlated with both fruit length (FL) and diameter (FD). Numerous QTLs have also been associated to FL but those located in chromosomes 2 and 8 have been detected in different genetic backgrounds and Gonzalo & Monforte, (2017) defined 4 Meta-QTLs for FW on chromosomes 2,3,8 and 11 and 5 additional Meta-QTLs on chromosomes 1, 2, 8, 11 and 12 for FS. Most of the later QTLs co-localized with those previously detected for FL and FS.…”

“…Acidity, along with sweetness, is a characteristic that determines melon quality. The flexuosus and acidulus groups are the most acidic compared to sweet melons (Gonzalo & Monforte, 2017). Acidity is controlled by the dominant gene So (Sour), located on chromosome 8, and its expression is ethylene independent (Burger et al, 2002;Harel-Beja et al, 2010).…”
