Plant-pathogenic begomoviruses have a complex association with their whitefly vector and aspects concerning virus genetic activity (genome replication and gene transcription) within the insect remain highly controversial. Virus transcript abundance was assessed by quantifying selected gene transcripts of Tomato mottle virus (ToMoV, a New World bipartite begomovirus) and Tomato yellow leaf curl ...

During a survey in 2020, Hormozgan province, the following symptoms were observed zucchini crops growing field: leaf curling, yellow mosaic, swelling of veins young leaves, and shortening internodes. Because importance Tomato Leaf Curl New Delhi Virus (ToLCNDV) other Iran, presence this virus plants was evaluated by PCR amplification coat protein gene. Sequence analysis confirmed ToLCNDV infect...

The female-biased infection of facultative symbionts has been found in Bemisia tabaci; however, whether there are any differences in tomato yellow leaf curl virus (TYLCV) and obligate symbiont infection rates between females and males is unknown. Determining whether such differences exist would be very important for understanding the spread of the plant virus and of the symbionts. We compared b...

Cucumber plants exhibiting virus-like disease symptoms were collected in various gardens and greenhouses in Lithuania. Viral diseases were expressed by symptoms of mosaicmottling, yellow ringspots and vein necrosis of leaves. Growth and fruiting of plants were reduced. Results of the identification of viruses detected in cucumbers by the RT-PCR technique are presented here. Identification of ca...

Viral diseases are major constraints to tomato, cucumber and mung bean production in most areas where these crops grown. To identify the viruses on Tajikistan, a field survey was conducted 2019. Samples of cucumber, tomato with virus-like symptoms were collected present diagnosed by RT-PCR PCR. Across all samples, very high proportion samples infected from genera Cucumovirus Potyvirus. Cucumber...

Circular single-stranded DNA (ssDNA) viruses are the smallest viruses known to infect eukaryotes. High recombination and mutation rates have conferred these viruses with an evolutionary potential that has facilitated their emergence. Their damaging effects on livestock (circoviruses) and crops (geminiviruses and nanoviruses), and the ubiquity of anelloviruses in human populations and other mamm...

tomato production, growing nearly 40 percent of world supply. The majority of fruit is processed into concentrated paste, but an increasing percentage is being used for products utilizing peeled fruit, either whole or diced. Important fruit quality attributes for paste production are soluble solids content (SS) and color of the blended product. Uniformity of color is more important for peeled f...
