Gene editing unlocks superior mutants from once detrimental RFL for enhanced rice yield traits.
(PubMed, Plant J)
- "Notably, the amino acid at position 266 was found to be a critical site for RFL regulation of grain shape, significantly affecting grain weight, with changes in the expression levels of genes involved in grain length and panicle weight regulation, such as GRF1 and SPL16. This study not only expands our understanding of the role of RFL in monocot plants but also provides a novel perspective on how gene editing can transform a gene once considered detrimental to improve yield traits in cereal crops. These findings suggest that the number of genes available for optimizing rice phenotypes through gene editing can be significantly increased."

A miR156-SPL module controls shade-induced inhibition of vascular cambium activity through cytokinin pathway in poplar.
(PubMed, Cell Rep)
- "Further molecular and genetic analyses revealed that SPL16/23 directly activate IPT5s/LOG1b expression to promote cambial activity. These findings unveil a miR156-SPL16/23-IPT5/LOG1-CK signaling pathway that mediates the inhibition of cambial activity and xylem development under shade conditions, providing valuable targets for the genetic improvement of shade-tolerant trees."

SPL16 and SPL23 mediate photoperiodic control of seasonal growth in Populus trees.
(PubMed, New Phytol)
- "Our results reveal a connection between the phyB-PIF8 module-mediated photoperiod perception and the miR156-SPL16/23-FT2/BRC1 regulatory cascades in SD-induced growth cessation. Our study provides insights into the rewiring of a conserved miR156-SPL module in the regulation of seasonal growth in Populus trees."
