Genomic Characterization of Xanthomonas cucurbitae, the Causal Agent of Bacterial Spot Disease of Cucurbits
Plants in the Cucurbitaceae family comprise several economically-important vegetable and fruit crops including pumpkin, squash, zucchini, cucumber, melon, and watermelon. In 2017, world production of pumpkins, squash, and gourds exceeded 24 million tons worth more than $4 billion, and U.S. production of pumpkins, squash, and gourds was worth $370 million. Illinois farmers are responsible for […]

Inheritance of Lethal Yellow Seedling in Cucurbita moschata Duch.
The lethal yellow seedling phenotype has been observed in seedlings of the genus Cucurbita. It was first reported in C. pepo (1) and more recently in C. maxima (2). In both cases a single recessive gene was reported to control the trait. It is reported here the occurrence and the inheritance of the lethal yellow […]
A Recessive Tendrilless Mutant in Ornamental Pumpkin
Tendrils are borne at leaf nodes and are a common morphological feature of most cucurbits. Reports of tendrilless mutants are rare in the cucurbit family. In a perusal of recent gene lists for the major cucurbits two tendrilless mutants were reported, one in cucumber (4) and the other in watermelon (3). In spring of 2010 […]
Tendril Morphology in Bush and Vine Genotypes of Squash and Pumpkin
Tendrils are threadlike, coiling organs differentiated from specialized lateral shoots initiated at leaf axils, and which function in mechanical support of plants with a vining habit of growth. Morphologically, they are commonly comprised of a basal stem or shoot axis of variable length which branches into tendrils which are thigmotropic, coiling around objects in which […]
Interaction of Three Loci, l-1, l-2, and d, in Conferring the Reverse Stripe Phenotype in Egg Gourd
There are more than a dozen described genes that govern rind color and rind color patterns in fruit of Cucurbita pepo L. (9), and expression of such traits is complex because colors and patterns can change at different stages of fruit development (11) and many of the gene loci affecting fruit pigmentation have multiple alleles. […]
Patterns of Broad Normal Striping in Egg Gourd
There are two general patterns of striped pigmentation patterns in Cucurbita pepo, reverse striping (3, 7), characterized by green narrow stripes over the vein tracts (vasculature) and wide white stripes between the vein tracts, and normal striping (5, 6, 8), characterized by narrow white to blue-gray stripes over vein tracts and wide green stripes between […]
