Beet curly top virus (BCTV), genus Curtovirus, and other closely related curtoviruses transmitted by the beet leafhopper Circulifer tenellus (Baker) have caused significant problems to irrigated agriculture in the western United States for over a century (4). BCTV is known to infect a broad range of crop and weed hosts in many plant families (1). The leafhopper vector also feeds and breeds on a...

ABSTRACT A random amplified polymorphic DNA (RAPD) marker directly linked (0.0 cM) with a resistance gene was identified in a snap bean recombinant inbred population (Moncayo x Primo) consisting of 94 F(5:7) recombinant inbred lines that had uniform segregation for disease reaction to Beet curly top virus (BCTV) across three field locations. Resistance was conditioned by a single dominant allel...

Neural tube defects (NTDs), such as spina bifida and anencephaly, are severe birth defects which result from failure of closure of the neural tube (the precursor of the brain and the spinal cord). In humans, NTDs affect 1 per 1000 pregnancies, with multifactorial aetiology suggestive of a combination of one or more genetic factors with contribution from environmental risk factors. The curly tai...

We analyzed the expression patterns of several pathogen defense-related genes in primary leaf buds of parsley by in situ RNA hybridization. Labeled antisense RNA probes were generated from seven selected cDNAs detecting transcripts from genes that are rapidly and strongly activated in cultured parsley cells upon treatment with fungal elicitor. These genes encode two enzymes of general phenylpro...

To study how plant architecture affects the canopy traits and water use of wheat, Triticum aestivum L. population is expected to provide important information for cultivar improvement ideal structure establishment conserving without causing an enormous grain yield loss. This was conducted three consecutive growing seasons using two genotypes with contrasting architectures as materials, upright-...
