Several viruses can cause devastating diseases in domestic apple (Malus x domestica Brokh.). Major viruses affecting apple production in New York are apple chlorotic leaf spot virus (ACLSV), apple stem pitting virus (ASPV), apple stem grooving virus (ASGV). These viruses are common and generally latent; in other words, they do not cause acute symptoms on most commercial cultivars. However, when...

A citrus tatter leaf isolate (CTLV-Cl) of Apple stem grooving virus (ASGV) has been found to be associated with a fruit rind intumescence in Cleopatra mandarin (Citrus reshni) in Limeira (SP). The CTLV-Cl was mechanically transmitted to the main experimental herbaceous hosts of CTLV. Chenopodium quinoa and C. amaranticolor reacted with local lesions and systemic symptoms while other test plants...

Citrus species grown in Japan are affected by several viruses and viroids, including satsuma dwarf virus, citrus vein enation exocortis viroid, other viroids. Recently, a comprehensive review was made on the occurrence, history, research of following three major Japan: tatter leaf virus (apple stem grooving virus), tristeza (Iwanami 2022). As sequel, this study reviews development viroids as we...

Low-chilling apple varieties are gaining attention in plain regions with high temperatures but viruses also adapting to these conditions. In this report, we have characterized Apple stem grooving virus and scar skin viroid from the low-chilling samples collected district District Mandla of Madhya Pradesh Kangra Himachal Pradesh, India. To our knowledge, is first report ASGV ASSVd infecting

Abstract Apple stem grooving virus, the causal agent of citrus tatterleaf disease, was detected for first time in Lao People’s Democratic Republic. Samples were collected from trees across southern provinces testing Australia. RNA extracted and tested using conventional real-time reverse transcription polymerase chain reactions with virus 1 59 samples tested. Viral identity confirmed by Sanger ...

Deep sequencing has generated 52 contigs derived from five viruses; Apple chlorotic leaf spot virus (ACLSV), Apple stem grooving virus (ASGV), Apple stem pitting virus (ASPV), Apple green crinkle associated virus (AGCaV), and Apricot latent virus (ApLV) were identified from eight apple samples showing small leaves and/or growth retardation. Nucleotide (nt) sequence identity of the assembled con...

A one-step multiplex real-time reverse transcription polymerase chain reaction (RT-qPCR) based on TaqMan probes was developed for the simultaneous detection of Apple mosaic virus (ApMV), Apple stem pitting virus (ASPV) and Apple stem grooving virus (ASGV) in total RNA of pome trees extracted with a CTAB method. The sensitivity of the method was established using in vitro synthesized viral trans...

Background and Aims: In spite of a long tradition of fruit-tree growing in all provinces of Iran, information on pear (Pyrus communis) tree viruses is scant. In order to identify of the nature of the virus like symptoms and decline in pear trees, we carried out a survey for the occurrence of four important viruses. Materials and Methods: Leaf samples of pear showing virus like symptoms wer...
