In this review we have summarized the emerging roles of sRNAs-regulated nodes in mediating plant pigmentation-associated biosynthetic pathways, focused on chlorophylls, flavonoids, carotenoids, and betalains. In addition, we discuss perspectives related to the manipulation of those genes associated with plant pigments for obtaining genetically improved plants.

We report that the phytohormones strigolactones promote tomato flowering. Our data suggest that this occurs via transcription of the florigen-encoding SINGLE-FLOWER TRUSS (SFT) gene in the leaves. SFT transcription is linked upstream to transcriptional reprogramming including increased levels of miR319 and decreased transcripts of its LANCEOLATE target, a repressor of SFT transcription, in the leaves and meristems. A higher content of gibberellins is also likely to contribute to the poor reproductive performance of strigolactone-depleted tomato. Our study opens novel opportunities to manage fruiting time and total yield for this crop.
