Special Issue "Regulations by Small RNA in Plant Development and Beyond"
Deadline for manuscript submissions: 31 July 2019
Dr. Chiara Pagliarani
Plants are subjected to several environmental stimuli during their lifetime and a fine transcriptome reprogramming is needed to allow the balance between the plant response to numerous stress factors and processes of plant growth and development. In this context, non-coding RNAs (ncRNAs) are fundamental players in the transcriptional and epigenetic regulatory mechanisms involved in the development and environmental adaptation of plants. Basing on their biogenesis, small RNAs are classified in different categories, such as miRNAs, siRNAs, and long ncRNAs, each exerting specific functions in gene regulation that often overlap with hormonal signalling cascades. Although in the last decade there was a real explosion of studies on plant small RNAs, many elements of RNA signalling pathways are still unsolved.
Papers submitted to this Special Issue should report novel and timely results unveiling key aspects of small RNA functions and the related silencing machinery in plants, including DNA methylation. Particular attention is directed to research studies concerning significant advances in small RNA-mediated signalling pathways crucial for the understanding of plant development, and of physiological and molecular responses to abiotic and biotic stress. Groundbreaking insights shedding new light on MIRNA genes and/or the diversification of miRNA biogenesis and functionality in plants are welcome as well.

Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Title: Small RNA: a cross-kingdom trafficking effector between different plant species and pathogens
Authors: Chen Zhu, Ting Liu and Cheng-Guo Duan
Abstract: Small RNA is a small but powerful agent that regulate development, abiotic and biotic stress resistance during plant adaptation in constant challenging living environment. Recent discoveries of small RNA bi-directional trafficking between fungi-plant and parasite-plant opened a new gate but also raised many interesting questions. The following demonstration of exosome mediated plant immunity introduced a possible tool in further investigating how plant uses small RNA as weapon in anti-fungal war. This review will focus on discussing the role of small RNA during plant immunity in 3 aspects: first, biogenesis of anti-fungal or parasite small RNA in plant; second, the transportation and working mechanism of these small RNA; third, the contribution of these small RNA in plant immunity.
Title: Comparative study of transcriptomes of Nicotiana benthamiana reveal activation of RNAi by sequences homologous and heterologous to Pepper golden mosaic virus
Author: Diana Medina Hernandez
Abstract: The efficiency of interfering RNA (RNAi) as a protection system used in constructions with sequences homologous to the challenged begomovirus is widely documented, demonstrating an efficiency of up to 100% in the control of the disease. However, because mixed infections are common in nature and some research has focused on evaluating the efficiency of RNAi as a protection system when the sequences are not homologous to the begomovirus that causes the disease or in the presence of different begomoviruses. This study compares the transcriptional changes and analyzes some genes that belong to the gene-silencing pathway, using sequences that are heterologous to the challenged begomovirus. Transcriptome analysis revealed that genes associated with RNAi and methylation, were induced by both constructs. Results of this study demonstrate that the RNAi mechanisms do not require the activation sequence be 100% identical to the target sequence and that it is possible to obtain a protective effect in Nicotiana benthamiana plants using heterologous RNAi constructs.
