Abstract
Due to global climate change, temperature stress has
become one of the primary causes of crop losses worldwide. Much progress has
been made in unraveling the complex stress response mechanisms in plants,
particularly in the identification of temperature stress
responsive protein-coding genes. Recently discovered microRNAs (miRNAs) and
endogenous small-interfering RNAs (siRNAs) have also been demonstrated as
important players in plant temperature stress response. Using high-throughput
sequencing, many small RNAs, especially miRNAs, have been identified to be triggered
by cold or heat. Subsequently, several studies have shown an important
functional role for these small RNAs in cold or heat tolerance. These findings
greatly broaden our understanding of endogenous small RNAs in plant stress
response control. Here, we highlight new findings regarding the roles of miRNAs
and siRNAs in plant temperature stress response and acclimation. We also review
current understanding of the regulatory mechanisms of small RNAs in temperature
stress response, and explore the outlook for the utilization of these small
RNAs in molecular breeding for improvement of temperature stress tolerance in
plants.
