- A regulatory circuit conferring varied flowering response to cold in annual and perennial plants
Annual and perennial plants diverge in flowering behavior by varying the balance between shared flowering-control pathways.
- Structural adaptations of photosynthetic complex I enable ferredoxin-dependent electron transfer
A proton-pumping machine in photosynthesis uses the common electron carrier ferredoxin.
- Synthetic glycolate metabolism pathways stimulate crop growth and productivity in the field
Tobacco plants carrying engineered glycolate metabolic pathways showed as much as 40% greater productivity than wild-type plants in field trials.
- A hidden cradle of plant evolution in Permian tropical lowlands
Late Permian (252-million- to 260-million-year-old) plant fossils from the Middle East shed light on the early origins of major seed-plant lineages.
- Root branching toward water involves posttranslational modification of transcription factor ARF7
Auxin hormone signaling links the direction of plant root branching with where water is available.
