“…Therefore, we present an example of the extensive and collaborative work that has focused on unraveling the intricacies in tripartite interactions involving begomoviruses. In the past decade, a joint effort from our laboratory and the laboratories of Professor Xue‐Ping Zhou (Zhejiang University) and Professor Rong‐Xiang Fang (Institute of Microbiology, Chinese Academy of Sciences) has begun to reveal the complexities of the interactions among begomoviruses, whitefly vectors and their shared host plants (Jiu et al ., 2007; Zhang et al ., 2012; Wang et al ., 2012, 2020; Luan et al ., 2013a,b; Li et al ., 2014; He et al ., 2015; P. Li et al ., 2017, 2019; Zhao et al ., 2019, 2021; He et al ., 2020; Wang et al ., 2020; Zou et al ., 2020). Our complementary studies demonstrate the feasibility of unraveling the underlying mechanisms, in particular the modulation and function of phytohormones, using a multidisciplinary, integrated approach that utilizes cutting‐edge technologies (Fig.…”

Attack of plants by both viruses and their vectors is common in nature. Yet the dynamics of the plant-virus-vector tripartite system, in particular the effects of viral infection on plant-insect interactions, have only begun to emerge in the last decade. Viruses can modulate the interactions between insect vectors and plants via the jasmonate, salicylic acid and ethylene phytohormone pathways, resulting in changes in fitness and viral transmission capacity of their insect vectors. Virus infection of plants may also modulate other phytohormones, such as auxin, gibberellins, cytokinins, brassinosteroids, and abscisic acid, with yet undefined consequences on plant-insect interactions. Moreover, virus infection in plants may incur changes to other plant traits, such as nutrition and secondary metabolites, that potentially contribute to virus-associated, phytohormone-mediated manipulation of plant-insect interactions. In this article, we review the research progress, discuss issues related to the complexity and variability of the viral modulation of plant interactions with insect vectors, and suggest future directions of research in this field.

“…Sinisterra et al (91) and Wang et al (94) detected increase of TYLCV transcripts in whiteflies during virus retention. Moreover, a whitefly transcription factor specifically bound to the TYLCCNV intergenic region was observed to promote viral gene transcription (95). These findings illustrate the increase of viral DNA and gene transcription in whiteflies after virus acquisition, which can hardly be explained without viral replication.…”

Of the approximately 1,200 plant virus species that have been described to date, nearly one-third are single-stranded DNA (ssDNA) viruses, and all are transmitted by insect vectors. However, most studies of vector transmission of plant viruses have focused on RNA viruses. All known plant ssDNA viruses belong to two economically important families, Geminiviridae and Nanoviridae, and in recent years, there have been increased efforts to understand whether they have evolved similar relationship with their respective insect vectors. This review describes the current understanding of ssDNA virus–vector interactions, including how these viruses cross insect vector cellular barriers, the responses of vectors to virus circulation, the possible existence of viral replication within insect vectors, and the three-way virus–vector–plant interactions. Despite recent breakthroughs in our understanding of these viruses, many aspects of plant ssDNA virus transmission remain elusive. More effort is needed to identify insect proteins that mediate the transmission of plant ssDNA viruses and to understand the complex virus–insect–plant three-way interactions in the field during natural infection. Expected final online publication date for the Annual Review of Entomology, Volume 66 is January 11, 2021. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

“…Removal of N ‐acetylation of TYLCCNB‐βC1 could attenuate virus‐induced symptoms and lead to ubiquitination and degradation of TYLCCNB‐βC1. [ 244 ] As we know that ubiquitination is a three‐step enzymatic reaction to activate, conjugate, and then ligation of ubiquitin protein with its substrate during PTGS pathway. E2 and E3 ligase proteins are very crucial in its function for determination of specific substrate for its targeted protein.…”

During plant–pathogen interaction, plant exhibits a strong defense system utilizing diverse groups of proteins to suppress the infection and subsequent establishment of the pathogen. However, in response, pathogens trigger an anti‐silencing mechanism to overcome the host defense machinery. Among plant viruses, geminiviruses are the second largest virus family with a worldwide distribution and continue to be production constraints to food, feed, and fiber crops. These viruses are spread by a diverse group of insects, predominantly by whiteflies, and are characterized by a single‐stranded DNA (ssDNA) genome coding for four to eight proteins that facilitate viral infection. The most effective means to managing these viruses is through an integrated disease management strategy that includes virus‐resistant cultivars, vector management, and cultural practices. Dynamic changes in this virus family enable the species to manipulate their genome organization to respond to external changes in the environment. Therefore, the evolutionary nature of geminiviruses leads to new and novel approaches for developing virus‐resistant cultivars and it is essential to study molecular ecology and evolution of geminiviruses. This review summarizes the multifunctionality of each geminivirus‐encoded protein. These protein‐based interactions trigger the abrupt changes in the host methyl cycle and signaling pathways that turn over protein normal production and impair the plant antiviral defense system. Studying these geminivirus interactions localized at cytoplasm‐nucleus could reveal a more clear picture of host–pathogen relation. Data collected from this antagonistic relationship among geminivirus, vector, and its host, will provide extensive knowledge on their virulence mode and diversity with climate change.
