Potato leafroll virus: A re‐emerging threat to sustainable potato production

Annals of Applied Biology, Volume 189, Issue 1, July 2026.
Potato leafroll virus (PLRV) is a positive‐strand RNA virus. Virus particles of PLRV are isometric, 24 nm in diameter. PLRV is the causal agent of leafroll disease in potato (Solanum tuberosum L.) which causes significant losses in yield and quality of potato tubers.

Identification of Tomato yellow leaf curl virus-Is in The Bahamas

Plant Disease, 2000
In December 1996, symptoms of stunting, curling, and marginal chlorosis of leaves, reduced leaf size, and marked reduction in number of fruits were first seen in tomato (Lycopersicon esculentum) plants on the island of North Andros, The Bahamas. Similar symptoms were observed for the first time during fall 1997 in tomatoes on the island of Eleuthera ...

Both Conserved Aromatic Nature and Critical RNA Motif of Residue 67 in the ToBRFV Movement Protein May Be Essential for Evading Tm‐22‐Mediated Resistance

Molecular Plant Pathology, Volume 27, Issue 7, July 2026.
Saturated mutagenesis of the MP C/H site reveals that residue identity at this position determines tobamovirus infection and Tm‐22 resistance evasion in tomato cultivars. ABSTRACT The 68th amino acid residue (cysteine, C68) in tobacco mosaic virus (TMV) movement protein (MP) and the corresponding position in some tobamoviruses are required to trigger ...

An efficient in vitro-inoculation method for Tomato yellow leaf curl virus [PDF]

Virology Journal, 2010
Tomato yellow leaf curl virus (TYLCV) is a member of the family Geminiviridae, genus Begomovirus. To test the infectivity of TYLCV in tomato plants, an improved protocol for inoculation of in vitro-cultured tomato plants was developed.A TYLCV isolate was cloned, sequenced and used to construct a 1.8-mer infectious clone.

Maize Streak Virus: diversity and virulence [PDF]

, 2000
Zea mays was first introduced to Africa in Ghana by Portuguese traders in the 16th century. The steady spread of maize cultivation since then has made it the most important cereal crop in Africa today.

SLCMV‐Encoded BC1 Protein Suppresses Photosynthesis by Disrupting Chloroplast Structure and Gene Expression

Molecular Plant Pathology, Volume 27, Issue 7, July 2026.
SLCMV infection suppresses photosynthesis by down‐regulating chloroplast‐ and photosystem‐related genes and disrupting chloroplast structure, a process largely mediated by the viral protein BC1. ABSTRACT Sri Lankan cassava mosaic virus (SLCMV) is a highly destructive plant virus that poses a significant threat to cassava cultivation.

Image_1_Resistance to Tomato Yellow Leaf Curl Virus in Tomato Germplasm.TIF [PDF]

, 2018
Tomato yellow leaf curl virus (TYLCV) is a virus species causing epidemics in tomato (Solanum lycopersicum) worldwide. Many efforts have been focused on identification of resistance sources by screening wild tomato species.
