“…originated in tropical Latin America and contained five cultivars (C. annuum, C. baccatum, C. chinense, C. frutescens, and C. pubescens) and was one of the oldest and most frequently produced vegetable crops globally (1). Virus disease was a serious disease in pepper production, affecting yield and quality of peppers in pepper production areas all over the world (2)(3)(4)(5). More than 70 plant viruses have been documented to infect peppers in various parts of the world since Doolittle initially identified the Cucumber Mosaic Virus (CMV) on peppers in 1923 (6)(7)(8)(9).…”

“…Pepper production in Venezuela for 2021 was 146,817 tons, with a harvested area of 10,126 ha and a yield of 144,996 hg/ha [3]. The pepper crop faces numerous challenges due to viral infections that can severely impact its production and quality on a global scale [4,5]. In the central and western regions of Venezuela, pepper cultivation serves as a significant agricultural activity, contributing to the nation's economy and food security.…”

Many plant virus outbreaks have been recorded in the last two decades, threatening food security around the world. During pepper production seasons in 2008, 2014, and 2022, virus outbreaks were reported from Lara (western) and Miranda (central) states in Venezuela. Three hundred seventy-three plants exhibiting virus-like symptoms were collected and tested for virus infection through reverse transcription PCR (RT-PCR). The most prevalent viruses during the 2008 surveys conducted in Lara were potato virus Y (PVY, 66.25%), cucumber mosaic virus (CMV, 57.50%), pepper mild mottle virus (PMMoV, 35%), alfalfa mosaic virus (AMV, 23.75%), and tobacco rattle virus (TRV, 17.50%). This survey revealed for the first time that pepper is a natural host of AMV and TRV in Venezuela. A further, divergent potyvirus isolate was also detected in 23.75% of pepper plants from Lara state. In 2014, a follow-up survey after virus outbreaks reported in Lara and Miranda states also detected this divergent potyvirus isolate in 21.68% of pepper plants, with tomato spotted wilt virus (TSWV) and PMMoV dominating the viral landscape (62.65 and 21.68% of tested plants, respectively). By comparison, the surveys revealed significant changes in viral community composition. The complete capsid protein (CP) sequence of the putative potyvirus was obtained from two pepper samples. According to the Potyvirus taxonomic criteria, these results suggest that the isolate represents a distinct virus species, for which we propose the name “pepper severe mottle virus” (PepSMoV). Virus outbreaks could be attributed to agricultural and environmental factors, such as climate change, the use of wastewater, the use of uncertified seeds, misuse of agricultural chemicals, transmission with food trade networks, and the development of new viral strains due to mutations and recombination and pathogen spillover. This study demonstrates the value of knowledge of the prevalence and distribution of viral species to recommend virus-resistant cultivars to replace susceptible ones, especially in virus hotspot areas.
