Summary Like metazoans, plants use small regulatory RNA s ( sRNA s) to direct gene expression. Several classes of sRNA s, which are distinguished by their origin and biogenesis, exist in plants. Among them, micro RNA s (mi RNA s) and trans ‐acting small interfering RNA s (ta‐si RNA s) mainly inhibit gene expression at post‐transcriptional levels. In the past decades, plant mi RNA s and ta‐si RNA s have been shown to be essential for numerous developmental processes, including growth and development of shoots, leaves, flowers, roots and seeds, among others. In addition, mi RNA s and ta‐si RNA s are also involved in the plant responses to abiotic and biotic stresses, such as drought, temperature, salinity, nutrient deprivation, bacteria, virus and others. This review summarizes the roles of mi RNA s and ta‐si RNA s in plant physiology and development.
