Representative models for the roles of plant long noncoding RNAs (lncRNAs). lncRNAs can serve as scaffolds, molecular mimics and sponges, and small interfering RNA precursors. They can also be translated into small peptides to regulate target genes in cis or in trans during plant development. The expression of most reported plant lncRNAs is induced by diverse environmental conditions. COLDAIR, COOLAIR, MAS, and LAIR are lncRNAs regulating mRNA transcription in cis. PMS1T is a lncRNA acting as a phasiRNA precursor. IPS1 regulates PHO2 by acting as the endogenous target mimic of miR399 and affects phosphate homeostasis together with another lncRNA, NATpho1;2. Pri-miR171b is a peptide-encoding lncRNA. PROMPTs and ASCO-lncRNA are protein-binding lncRNAs that suppress the function of target proteins.
