overhead irrigation exclusively while those on plastic use drip irrigation. Disease and insect pressure are lowest in spring plantings, which are started in early to mid-March in southwest Georgia. Growers typically use cultivars with little to no virus

Arizona in 2006 ( Kuo et al., 2007 ). It occurred in Florida in 2007 and Georgia in 2017 but has not been as severe as in California ( Gadhave et al., 2018 ; Polston et al., 2008 ). Cucurbit chlorotic yellows virus (CCYV; genus Crinivirus , family

shown in herbaceous systems that manifestation of disease symptoms in grafted tissues is preceded by the delivery of virus RNA ( Más and Pállas, 1996 ). It is possible that the GAFP-1 lectin may not be compatible with the phloem transportation

(CGMMV) in M 2 plants in the field. T = tested sample comprising a mixture of RNAs from 14 M 2 plants with virus-like symptoms in the field; N = negative sample of a healthy plant; M = marker. The middle line with Cp-1, Cp-2, etc., indicates the

Sweetpotato whitefly, Bemisia tabaci (Gennadius), adversely affects yield and quality of a wide range of vegetable and agronomic crops worldwide directly through feeding damage or indirectly as virus vectors ( Henneberry et al., 1998 ). It is

after potato. In the last decades, the viral diseases have become the main limiting factor in tomato crops along the Spanish Mediterranean coast and in many other areas in the world. In this respect, Tomato spotted wilt virus (TSWV) and Tomato yellow

‘Moixent’ is a self-compatible, early-ripening apricot cultivar ( Prunus armeniaca L.) with excellent fruit quality and resistance to sharka (plum pox virus), a serious disease limiting apricot fruit production in affected areas. ‘Moixent’ fruits

phenotype occurred in a population of transgenic plants expressing an extra copy of Chs ( Napoli et al., 1990 ; van der Krol et al., 1990 ). This cosuppression phenomenon was shown to be the result of Chs messenger RNA (mRNA) degradation ( Metzlaff et

‘Rafel’ and ‘Belgida’ are mid- to early-ripening apricot cultivars ( Prunus armeniaca L.) with good yield, excellent fruit quality, self-compatibility, and resistance to Sharka, a disease caused by the Plum pox virus , a serious limiting factor
