“…Using RNAseq, 664 drought-responsive lncRNAs were identified in maize. Among them, 567 lncRNAs were up-regulated and 97 lncRNAs were down-regulated in droughtstressed leaves of maize (Zhang et al, 2014a). Nonetheless, no lncRNA that functions in the plant response to drought or salt stress tolerance has been characterized in detail.…”

“…Several reports also show that drought or salt stress could alter lncRNA expression in plants. For example,19,664, and 98 drought-responsive lncRNAs were identified in foxtail millet (Setaria italica), maize (Zea mays), and rice, respectively (Qi et al, 2013;Zhang et al, 2014a;Chung et al, 2016). Salt stress and dehydration stress also alter the accumulation of eight and six lncRNAs, respectively, in Arabidopsis (Arabidopsis thaliana; Ben Amor et al, 2009).…”

Long noncoding RNAs (lncRNAs) affect gene expression through a wide range of mechanisms and are considered as important regulators in many essential biological processes. A large number of lncRNA transcripts have been predicted or identified in plants in recent years. However, the biological functions for most of them are still unknown. In this study, we identified an Arabidopsis (Arabidopsis thaliana) lncRNA, DROUGHT INDUCED lncRNA (DRIR), as a novel positive regulator of the plant response to drought and salt stress. DRIR was expressed at a low level under nonstress conditions but can be significantly activated by drought and salt stress as well as by abscisic acid (ABA) treatment. We identified a T-DNA insertion mutant, drir D , which had higher expression of the DRIR gene than the wild-type plants. The drir D mutant exhibits increased tolerance to drought and salt stress. Overexpressing DRIR in Arabidopsis also increased tolerance to drought and salt stress of the transgenic plants. The drir D mutant and the overexpressing seedlings are more sensitive to ABA than the wild type in stomata closure and seedling growth. Genome-wide transcriptome analysis demonstrated that the expression of a large number of genes was altered in drir D and the overexpressing plants. These include genes involved in ABA signaling, water transport, and other stress-relief processes. Our study reveals a mechanism whereby DRIR regulates the plant response to abiotic stress by modulating the expression of a series of genes involved in the stress response.

“…A growing body of evidence indicates that plant lncRNAs have critical biological roles (e.g., cell differentiation, epigenetic modification, genomic imprinting, and stress tolerance) in different physiological and environmental conditions (Charon et al, 1997;Pignatta and Gehring, 2012;Heo et al, 2013;Zhang et al, 2014). However, detailed information for specific plant lncRNA(s) are widely dispersed in current scientific publications.…”

“…These RNA molecules are longer than 200 bp and do not encode any protein product. The recent studies have linked them to such processes as gene silencing, flowering time regulation, and abiotic stress responses Zhang et al 2014). Identification of lncRNAs is performed using tiling array, EST analyses, and RNA sequencing.…”

In the past decade, next-generation sequencing (NGS) platforms have changed the impact of sequencing on our knowledge of crop genomes and gene regulation. These techniques are today acquiring a great potential in metagenomic and agrigenomic research while showing prospects for their utilization in plant breeding. We can now obtain new and beneficial information about gene regulation on the cellular as well as whole-plant level through RNA-sequencing and subsequent expression analyses of genes participating in plant defence reactions to pathogens and in abiotic stress tolerance. NGS has facilitated the development of methods to genotype very large numbers of single-nucleotide polymorphisms. Genotyping-by-sequencing and whole-genome resequencing can lead to the development of molecular markers suited to studies of genetic relationships among breeding materials, creation of detailed genetic mapping of targeted genes and genome-wide association studies. Plant genotyping can benefit plant breeding through selection of individuals resistant to climatic stress and to pathogens causing substantial losses in agriculture.
