The study identifies the transcription factor MdBRC1 as a key inhibitor of bud growth during the ecodormancy phase in apple (Malus domestica), directly regulating dormancy‑associated genes and interacting with the flowering promoter MdFT2 to modulate bud break. Comparative transcriptomic analysis and gain‑of‑function experiments in poplar demonstrate that MdFT2 physically binds MdBRC1, attenuating its repressive activity and acting as a molecular switch for the transition to active growth.

The study introduced full-length SOC1 genes from maize and soybean, and a partial SOC1 gene from blueberry, into tomato plants under constitutive promoters. While VcSOC1K and ZmSOC1 accelerated flowering, all three transgenes increased fruit number per plant mainly by promoting branching, and transcriptomic profiling revealed alterations in flowering, growth, and stress‑response pathways.

The study demonstrates that the microtubule‑associated protein WDL4 is essential for PhyB‑dependent thermomorphogenic and photomorphogenic responses in Arabidopsis, as wdl4-3 mutants mimic phyB loss‑of‑function phenotypes under varying temperatures and light conditions. Genetic analyses reveal that PIF4 activity is required for wdl4-3 hypocotyl hyper‑elongation, and while exogenous auxin can rescue pif4‑related defects, it does not restore the wdl4-3 specific elongation, indicating additional regulatory layers.
