2022年9月26日 · Symptoms begin on older leaves near the crown and gradually spread toward newer foliage. Early symptoms consist of a chlorotic or yellow mottle on older leaves that eventually coalesce into interveinal chlorosis, with veins …

Symptoms of CCYV infection do not develop until approximately three weeks after infection. On cucurbit plants, symptoms usually begin as chlorotic (yellow) spots and rapidly develop into a chlorotic mottle (Figure 1). As symptoms advance, the chlorotic spots coalesce, developing into interveinal chlorosis (chlorosis between veins; Figure 2).

Symptoms of CCYV infection do not develop until approximately three weeks after infection. On cucurbit plants, symptoms usually begin as chlorotic (yellow) spots and rapidly develop into a chlorotic mottle (Figure 1). As symptoms advance, the chlorotic spots coalesce, developing into interveinal chlorosis (chlorosis between veins) (Figure 2).

Cucurbit chlorotic yellows virus (CCYV) is another emerging crinivirus, which was first reported in 2009 to infect cucurbit in Japan (Okuda et al., 2010) and later in different countries (Gu et al., 2011; Orfanidou et al., 2014; Kheireddine et al., 2014).

Cucurbit chlorotic yellows virus (CCYV) (genus Crinivirus, family Closteroviridae) is implicated in cucurbit yellows disease (CYV), causing typical interveinal yellowing symptoms in leaves, and is transmitted by Bemisia tabaci Mediterranean (MED) and Middle East-Asia Minor 1 (MEAM1).

The Cucumber chlorotic virus (CCYV) is transmitted by the whitefly, Bemisia tabaci and has caused great losses in vegetable production. Up to now, there are many reports in northern cities, but there is no report in Hunan province. In a survey in Hunan province in 2016, the symptoms of chlorosis were found on cucumber leaves.

2023年9月28日 · High-throughput sequencing of viral RNA extracted from symptomatic leaves revealed the presence of cucurbit chlorotic yellows virus (CCYV), a crinivirus in the Closteroviridae family. The complete viral genome sequence was obtained using RT-PCR followed by Sanger sequencing.

2018年5月24日 · Background: Cucurbit chlorotic yellows virus (CCYV), a bipartite crinivirus, causes chlorotic leaf spots and yellowing symptoms on cucurbit leaves. We previously developed an infectious clone of CCYV. Limited work has been conducted on the construction of a crinivirus green fluorescence protein (GFP) expression vector to date.

Cucurbit chlorotic yellows virus (CCYV) causes chlorotic yellows on cucumber (Cucumis sativus) and melon (Cucumis melo) and is transmitted by Bemisia tabaci biotype B and Q whiteflies. To characterize the host range of CCYV, 21 cucurbitaceous and 12 other plant species were inoculated using whitefly …

Cucurbit chlorotic yellows virus (Crinivirus, CCYV) is a virus transmitted by Bemisia tabaci (Hemiptera: Aleyrodidae – EPPO A2 List) which was first identified in Asia in 2004 and was causing damage to melon (Cucumis melo), watermelon (Citrullus lanatus) and cucumber (Cucumis sativus) crops in China, Japan, and Taiwan (EPPO RS 2011/007).
