A combination of plasma membrane sterol biosynthesis and autophagy is required for shade-induced hypocotyl elongation

HIGHLIGHTS

SUMMARY

    In contrast, LRFR induced anabolism including expression of sterol biosynthesis genes in hypocotyls in a manner dependent on PHYTOCHROMEINTERACTING FACTORs (PIFs). In shadeavoiding plants, LB and LRFR independently trigger a suite of similar adaptive responses, including the growth of stem-like structures including hypocotyls and petioles to enhance light access4-7. LB and LRFR induce distinct transcriptional changes in elongating hypocotyls Consistent with previous studies24,26, LB and LRFR treatments independently induced hypocotyl elongation in a PIF and YUC-dependent Nature Communications | 13:5659 manner (Fig 1a). The authors hypothesized a convergence of LB . . .
