Abstract
Virus induced gene silencing (VIGS) has, of late, emerged as an important tool for transient silencing of genes in plants. This is now being increasingly used to determine functions of novel genes in a wide variety of plants, many of which are important crops yielding food and fiber or are sources of products having pharmaceutical uses. The technology for VIGS comprises the development of vectors derived from viruses, choosing the optimal orientation and size of the gene to be targeted and adopting the most suitable method of inoculation. This review gives a brief overview of the main aspects of VIGS technology as is being practiced. It also discusses the challenges the technology faces and the possible way ahead to improve its robustness, so that the technology finds wider applications.

Abstract
Abstract
With the development of bioinformatics, it is easy to obtain information and data about thousands of genes, but the determination of the functions of these genes depends on methods for rapid and effective functional identification. Virus-induced gene silencing (VIGS) is a mature method of gene functional identification developed over the last 20 years, which has been widely used in many research fields involving many species. Fruit quality formation is a complex biological process, which is closely related to ripening. Here, we review the progress and contribution of VIGS to our understanding of fruit biology and its advantages and disadvantages in determining gene function.

Abstract
Over a hundred years of research on plant viruses has led to a detailed understanding of viral replication, movement, and host-virus interactions. The functions of vast viral genes have also been annotated. With an increased understanding of plant viruses and plant-virus interactions, various viruses have been developed as vectors to modulate gene expressions for functional studies as well as for fulfilling the needs in biotechnology. These approaches are invaluable not only for molecular breeding and functional genomics studies related to pivotal agronomic traits, but also for the production of vaccines and health-promoting carotenoids. This review summarizes the latest progress in these forefronts as well as the available viral vectors for economically important crops and beyond.

Int J Mol Sci 2019; 20:ijms20236038. [PMID: 31801204 PMCID: PMC6928788 DOI: 10.3390/ijms20236038] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2019] [Revised: 11/19/2019] [Accepted: 11/27/2019] [Indexed: 12/26/2022] Open
Abstract
The JASMONATE ZIM DOMAIN (JAZ) proteins act as negative regulators in the jasmonic acid (JA) signaling pathways of plants, and these proteins have been reported to play key roles in plant secondary metabolism mediated by JA. In this study, we firstly isolated one JAZ from P. cablin, PatJAZ6, which was characterized and revealed based on multiple alignments and a phylogenic tree analysis. The result of subcellular localization indicated that the PatJAZ6 protein was located in the nucleus of plant protoplasts. The expression level of PatJAZ6 was significantly induced by the methyl jasmonate (MeJA). Furthermore, by means of yeast two-hybrid screening, we identified two transcription factors that interact with the PatJAZ6, the PatMYC2b1 and PatMYC2b2. Virus-induced gene silencing (VIGS) of PatJAZ6 caused a decrease in expression abundance, resulting in a significant increase in the accumulation of patchouli alcohol. Moreover, we overexpressed PatJAZ6 in P. cablin, which down-regulated the patchoulol synthase expression, and then suppressed the biosynthesis of patchouli alcohol. The results demonstrate that PatJAZ6 probably acts as a repressor in the regulation of patchouli alcohol biosynthesis, contributed to a model proposed for the potential JA signaling pathway in P. cablin.
