Autopolyploidization‐Induced Chromatin Remodeling Regulates Leaf Size Variation in Brassica rapa

Advanced Science, EarlyView.
This study demonstrates that monoploid, diploid, and autotetraploid Brassica rapa lines derived from the same genome exhibit distinct leaf morphology. Ploidy changes remodel chromatin accessibility and histone modifications to regulate gene expression, while key transcription factors BrGRF13 and BrARF11 control leaf size and polarity, driving ...

GbWAKL20 Phosphorylates GbNFYB8 to Modulate Verticillium Wilt Resistance in Cotton

Advanced Science, EarlyView.
Wall‐associated receptor‐like kinases (WAKLs) play pivotal roles in extracellular–intracellular signal transduction. Upon sensing Verticillium dahliae infestation at the plasma membrane, GbWAKL20 accumulates and transmits signals to the nucleus via endoplasmic reticulum‐mediated Golgi vesicle transport.

Zmienność i współzależność cech lucerny (Medicago sativa ssp. L.) o różnej długości kwiatostanu

Biuletyn Instytutu Hodowli i Aklimatyzacji Roślin, 2007
Od wielu lat prowadzone są prace hodowlane mające na celu poprawienie produktywności nasiennej uprawianych w naszym kraju lucern. Celem niniejszego opracowania była analiza produktywności nasiennej oraz ekspresji cech plonotwórczych form lucerny o różnej długości produktywnej części grona. Wydzielono trzy grupy fenotypowe: pędy o długich gronach (formy
