Translocation of Photosynthate in Curly Top Virus-infected Tomatoes.
Photosynthate translocation in single leaflets of healthy and curly top virus-infected tomatoes was investigated using (14)C as a marker. The amount of radioactivity found in plant parts not exposed to (14)CO(2) was substantially lower in diseased than in healthy plants. The time lag for the appearance of (14)C in the petiole was considerably longer in the infected plants than in the healthy. T...
متن کاملApetiolar photosynthate translocation.
Apetiolar transport of photosynthate (-14)C has been studied by feeding of (14)CO(2) to soybean petioles. Translocation occurs in the absence of leaves, but both the rate and velocity are diminished. The effect of root excision is not as profound as that of leaves. It appears, in some instances, to inhibit transport partially, so that accumulation of photosynthate develops, giving a steeper iso...
متن کاملGenome Sequences of Beet curly top Iran virus, Oat dwarf virus, Turnip curly top virus, and Wheat dwarf virus Identified in Leafhoppers
Implementation of a vector-enabled metagenomics approach resulted in the identification of various geminiviruses. We identified the genome sequences of Beet curly top Iran virus, Turnip curly top viruses, Oat dwarf viruses, the first from Iran, and Wheat dwarf virus from leafhoppers feeding on beet, parsley, pumpkin, and turnip plants.
متن کاملSeed Transmission of Beet Curly Top Virus and Beet Curly Top Iran Virus in a Local Cultivar of Petunia in Iran
Beet curly top virus (BCTV) and beet curly top Iran virus (BCTIV) are known as the causal agents of curly top disease in beet and several other dicotyledonous plants in Iran. These viruses are transmitted by Circulifer species, and until now, there has been no confirmed report of their seed transmission. A percentage (38.2-78.0%) of the seedlings developed from the seeds of a petunia local cult...
متن کاملInvolvement of C4 Protein of Beet Severe Curly Top Virus (Family Geminiviridae) in Virus Movement
BACKGROUND Beet severe curly top virus (BSCTV) is a leafhopper transmitted geminivirus with a monopartite genome. C4 proteins encoded by geminivirus play an important role in virus/plant interaction. METHODS AND FINDINGS To understand the function of C4 encoded by BSCTV, two BSCTV mutants were constructed by introducing termination codons in ORF C4 without affecting the amino acids encoded by...
