Abstract: Long noncoding RNAs(lncRNAs)refers to those RNAs having >200 nucleotides while containing ORF of less than 100 amino acids.. Based on their locations to nearby protein-coding genes,lncRNAs can be roughly classified into four types:long noncoding natural antisense transcripts(lincNATs),intron lncRNAs,promoter lncRNAs and long intergenic ncRNAs(lincRNAs). lncRNAs can function as recruiters,tethers,guides,decoys and signals for other biological molecules via interactions with epigenetic,transcriptional,post-transcriptional and translation control. A larger number of lncRNAs have been identified in many plant species and have shown to be important regulators in plant growth and development such as vernalization and flowering induction,formation of nodules in leguminous plants,pollen development and male sterility,photomorphogenesis,Pi absorption,lateral root development,auxin transport and development signal output,plant responses to diverse stresses and diseases,etc. lncRNAs are of great significance for the regulation of plant growth and development,also potent tools for the improvement of crop cultivar. In recent years,the research on plant lncRNAs increased drastically,and the literature on this field has grown rapidly. This review integrates the current knowledge on the classification,identification and research,molecular regulatory mechanisms and functions of plant lncRNAs in order to provide references for researchers.
