First Report of Cotton Leafroll Dwarf Virus in Upland Cotton (Gossypium hirsutum) in Mississippi

Genome analysis of cotton leafroll dwarf virus reveals variability in the silencing suppressor protein, genotypes and genomic recombinants in the USA

“…In addition to Africa and South America, CLRDV has also been reported in Timor-Leste [ 14 ], Thailand [ 15 ], India [ 16 ], and from Soybean aphid ( Aphis glycines ) in China [ 17 ]. Recently, there have been several reports on the detection of CLRDV in the USA: Arkansas [ 18 ], Alabama [ 19 ], Florida [ 20 ], Georgia [ 21 ], Kansas [ 22 ], Louisiana [ 23 ], Mississippi [ 24 ], North Carolina [ 25 ], Oklahoma [ 26 ], South Carolina [ 27 ] and Texas [ 28 ]. Since the first report of CLRDV, it has been detected in all the major cotton-growing counties in Georgia with 0–30% of disease incidence.…”

Genome Sequence of Cotton Leafroll Dwarf Virus Infecting Cotton in Georgia, USA

“…Cotton leafroll dwarf virus (CLRDV), a phloem-limited virus, is associated with the emerging cotton leafroll dwarf disease (CLRDD) in the United States. It was first reported from Alabama in 2019 ( 2 ) and subsequently from the major cotton-growing regions in the United States, including Florida ( 3 ), Georgia ( 4 ), Louisiana ( 5 ), Mississippi ( 6 ), South Carolina ( 7 ), and Texas ( 8 ). Symptoms of the disease include reddening of the leaves and petioles and drooling, crinkling, and deformation of the leaves ( Fig.…”

What we know about poleroviruses: Advances in understanding the functions of polerovirus proteins

“…Poleroviruses are important pathogens of many major crops, and therefore represent a threat to global food security. Human activities like farming and trading have favoured not only their spread (as well as that of their insect vectors) worldwide (Aboughanem‐Sabanadzovic et al, 2019; Agrofoglio et al, 2017; Avelar et al, 2019; Gonçalves et al, 2017; Sun, Chen, et al, 2020), but also the emergence of new poleroviruses infecting maize, cotton, potato, pepper, sugarcane, wheat, melon, and sugar beet, among others. Currently, these diseases are mostly managed by insecticide applications, with the entailed economic and environmental concerns.…”
