Viral Diseases of Pitaya and Other Cactaceae Plants
Improving Pitaya Production and Marketing VIRAL DISEASES OF PITAYA AND OTHER CACTACEAE PLANTS Yong-Shi Li1, Ching-Hua Mao1, Ting-Yi Kuo2, and Ya-Chun Chang1 1 Department of Plant Pathology and Microbiology, National Taiwan University, Taipei, Taiwan 2 Master Program for Plant Medicine, National Taiwan University, Taipei, Taiwan E-mail: [email protected] ABSTRACT Pitaya (Hylocereus spp.), also called dragon fruit, pitahaya or pitajaya, native to the forests of Latin America, and the West Indies, belongs to the family of Cactaceae. Among the cactus fruit crops, pitaya is classified as the climbing epiphytic species and produces edible fruits which have sweet pulps with numerous small black seeds on the trailing cladode stems. Due to the progress in breeding and cultivation techniques in Taiwan, pitaya is becoming an important fruit crop in the domestic and foreign markets. During a disease survey of pitaya in Taiwan, some plants were found with systemic mild mottling on the stems, and these were found to be infected by a potexvirus, Cactus virus X (CVX). In addition, another two potexviruses Zygocactus virus X (ZyVX) and Pitaya virus X (PiVX), were identified later in Taiwan. Because of the similar features of Cactaceae plants, there is high possibility that cactus-infecting viruses will infect pitaya just like CVX and ZyVX did. The objective of this article is to provide information of viral diseases of pitaya and other Cactaceae plants so as to help further study of pitaya- infecting viruses and propose the control strategy. Keywords: pitaya, Hylocereus, Cactaceae, viral diseases INTRODUCTION Pitaya, also called dragon fruit, pitahaya or pitajaya, native to the forests of northern South America, Central America, Mexico, and the West Indies, belongs to the genus Hylocereus in the family of Cactaceae (Mizrahi et al. -

Identification of Emerging Viral Genomes in Transcriptomic Datasets of Alfalfa (Medicago Sativa L.) Peng Jiang, Jonathan Shao and Lev G
Jiang et al. Virology Journal (2019) 16:153 https://doi.org/10.1186/s12985-019-1257-y RESEARCH Open Access Identification of emerging viral genomes in transcriptomic datasets of alfalfa (Medicago sativa L.) Peng Jiang, Jonathan Shao and Lev G. Nemchinov* Abstract Background: Publicly available transcriptomic datasets have become a valuable tool for the discovery of new pathogens, particularly viruses. In this study, several coding-complete viral genomes previously not found or experimentally confirmed in alfalfa were identified in the plant datasets retrieved from the NCBI Sequence Read Archive. Methods: Publicly available Medicago spp. transcriptomic datasets were retrieved from the NCBI SRA database. The raw reads were first mapped to the reference genomes of Medicago sativa and Medigago truncatula followed by the alignment of the unmapped reads to the NCBI viral genome database and de novo assembly using the SPAdes tool. When possible, assemblies were experimentally confirmed using 5′/3′ RACE and RT-PCRs. Results: Twenty three different viruses were identified in the analyzed datasets, of which several represented emerging viruses not reported in alfalfa prior to this study. Among them were two strains of cnidium vein yellowing virus, lychnis mottle virus and Cactus virus X, for which coding-complete genomic sequences were obtained by a de novo assembly. Conclusions: The results improve our knowledge of the diversity and host range of viruses infecting alfalfa, provide essential tools for their diagnostics and characterization and demonstrate the utility of transcriptomic datasets for the discovery of new pathogens.
