Natural variation in OsMYB305 downregulating cytokinin‐mediated inhibition of leaf senescence contributes to regional adaptation in rice

New Phytologist, EarlyView.
Proposed regulatory model of OsMYB305 in leaf senescence. Summary Accumulating evidence has identified transcription factors (TFs) as key regulators of the onset and progression of leaf senescence. However, the regulatory role of the rice myeloblastosis (MYB) TF OsMYB305 in this process remains largely unknown.

Evidence for a trade‐off between growth rate and xylem embolism resistance in 22 Eucalyptus species

New Phytologist, EarlyView.
Examples of cross‐sectional images of branchlets at 4× and 40×. Summary Within the growth–survival trade‐off framework, embolism resistance is considered a contributor to survival, yet whether greater embolism resistance inherently limits growth remains unclear.
