Transcriptome profiling of pumpkin (Cucurbita moschata Duch.) leaves infected with powdery mildew
Cucurbit powdery mildew (PM) is one of the most severe fungal diseases, but the molecular mechanisms underlying PM resistance remain largely unknown, especially in pumpkin (Cucurbita moschata Duch.). The goal of this study was to identify gene expression differences in PM-treated plants (harvested at 24 h and 48 h after inoculation) and untreated (control) plants of inbred line "112-2" using RN...
متن کاملCultivar-Based Introgression Mapping Reveals Wild Species-Derived Pm-0, the Major Powdery Mildew Resistance Locus in Squash
Powdery mildew is a major fungal disease on squash and pumpkin (Cucurbita spp.) in the US and throughout the world. Genetic resistance to the disease is not known to occur naturally within Cucurbita pepo and only infrequently in Cucurbita moschata, but has been achieved in both species through the introgression of a major resistance gene from the wild species Cucurbita okeechobeensis subsp. mar...
متن کاملMorphological, Thermal and Physicochemical Properties of Starches from Squash (Cucurbita maxima) and Pumpkin (Cucurbita moschata)
The properties of starches isolated from two squash cultivars (Cucurbita maxima) were studied and compared with those of two pumpkin cultivars (Cucurbita moschata) and one normal potato cultivar. The amylose content of pumpkin and squash starches ranged from 16.18% to 21.29%. The pumpkin and squash starches appeared as a mixture of spherical, polyhedral and dome shaped granules. The pumpkin and...
متن کاملInheritance Studies of the Interspecific Cross of the Cucurbita Lundelliana Complex X Cucurbita Moschata
Two populations of Cucurbita were studied for the inheritance of corolla pigments. Flowers from them were collected--classified as orange, yellow, or cream--and analyzed for total carotenoid pigments. In most cases, chemical analysis for total pigments agreed with observed color designations. The ? 2 and backcross results fitted the expected 1:2:1 and 1:1 segregations, respectively, found in th...
