Abstract
- Horticulture is one of the oldest agricultural practices with great popularity throughout the world. Horticultural crops include fruits, vegetables, ornamental plants, as well as medicinal and beverage plants. They are cultivated for food, specific nutrition, and medical use, or for aesthetic pleasure. MicroRNAs (miRNAs), which constitute a major class of endogenous small RNAs in plants, affect a multitude of developmental and physiological processes by imparting sequence specificity to gene regulation. Over the past decade, tens of thousands of miRNAs have been identified in more than 100 horticultural crops and their critical roles in regulating quality development of diverse horticultural crops have been demonstrated. Here, we review how miRNAs have emerged as important regulators and promising tools for horticultural crop improvement. MicroRNAs (miRNAs) constitute a major class of endogenous small RNAs in plants and their base pairing to complementary transcripts leads to gene silencing. Their functions in model plants suggest that they play critical roles in a variety of biological processes, including plant development and stress responses. In the past decade, the identification and functional analysis of miRNAs in various horticultural crops (plants of unique economical and ecological significance) have revealed that miRNAs are important and promising regulatory tools for crop quality improvement. Accumulating evidence supports a highly conserved regulatory circuit around the miR156/SPL module in horticultural crops, but there is obvious differentiation of this module in the regulation of growth and development, quality development in particular.
