Rapid evolution of gene expression patterns in flowering plants

This study shows that gene expression patterns in flowering plants evolve rapidly, with divergence rates exceeding those in mammals, and highlights differences in conservation across organs.

KAI2 regulates seedling development by mediating light-induced remodelling of auxin transport

This study shows KAI2 regulates light-induced auxin transport remodeling in seedlings by controlling PIN protein abundance, not gene expression, and its loss leads to altered growth patterns.

Blocking plasmodesmata in specific phloem cell types reduces axillary bud growth in Arabidopsis thaliana

The paper shows that blocking plasmodesmata in phloem cells of Arabidopsis reduces axillary bud growth rates without affecting bud activation.

An ABA-GA bistable switch can account for natural variation in the variability of Arabidopsis seed germination time

The paper examines phenotypic variability in Arabidopsis seed germination time, identifies two loci involved, and models a GA/ABA bistable switch that amplifies variability and contributes to bet hedging.

Cross-species functional diversity within the PIN auxin efflux protein family

The paper investigates functional differences between SoPIN1 and PIN1b in grasses and Arabidopsis, showing distinct roles in organ initiation and stem growth.
