Abstract：Tomato (Lycopersicon esculentum) has emerged as an emblematic model plants for tomato fruit ripening and senescence, and tomato fruit ripening is a complex and highly coordinated developmental process which is companied by color, texture, flavor, aroma and other metabolic physiological and biochemical changes. In recent years, small RNAs are new post-transcriptional regulatory factors which received more and more attentions and take part in almost all physiological and biochemical processes in plants and animals. In plants, small RNAs participate in development, fruit ripening, and biological and abiotic stress process. This paper systematically summarized the current situation of small RNAs and the small RNAs related to ethylene pathway, fruit color, fruit flavor, fruit softening and other metabolic process. It also emphasized the new perspectives now possible in the small RNAs regulation research in tomato fruit ripening and senescence.
