Seed Transmission of Pseudoperonospora cubensis
Pseudoperonospora cubensis, an obligate biotrophic oomycete causing devastating foliar disease in species of the Cucurbitaceae family, was never reported in seeds or transmitted by seeds. We now show that P. cubensis occurs in fruits and seeds of downy mildew-infected plants but not in fruits or seeds of healthy plants. About 6.7% of the fruits collected during 2012-2014 have developed downy mi...
متن کاملAlternative Splicing in the Obligate Biotrophic Oomycete Pathogen Pseudoperonospora cubensis.
Pseudoperonospora cubensis is an obligate pathogen and causative agent of cucurbit downy mildew. To help advance our understanding of the pathogenicity of P. cubensis, we used RNA-Seq to improve the quality of its reference genome sequence. We also characterized the RNA-Seq dataset to inventory transcript isoforms and infer alternative splicing during different stages of its development. Almost...
متن کاملGenetic and pathogenic relatedness of Pseudoperonospora cubensis and P. humuli.
The most economically important plant pathogens in the genus Pseudoperonospora (family Peronosporaceae) are Pseudoperonospora cubensis and P. humuli, causal agents of downy mildew on cucurbits and hop, respectively. Recently, P. humuli was reduced to a taxonomic synonym of P. cubensis based on internal transcribed spacer (ITS) sequence data and morphological characteristics. Nomenclature has ma...
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...
