Computational investigation of early events in plant growth signaling
… on the two primary brassinosteroid coreceptors, BRI1 and BAK1, we use a number of computational methods grounded in molecular dynamics simulations with the goal of understanding the physical mechanisms of brassinosteroid-induced BRI1-BAK1 association and activation. First, we examine the …

Crosstalk of protein phosphorylation and lysine acetylation on 14-3-3 proteins and their applications in brassinosteroid signaling and photosynthesis
… 14-3-3ω by the brassinosteroid receptor kinase BRI1 and its co-receptor BAK1. We identified eight novel Ser/Thr residues that were phosphorylated by BRI1 and/or BAK1 in vitro. Four of these phosphorylation sites (Thr-41, Thr-83, Thr94 and Thr-140) were confirmed to be present in planta in …

Avoiding trade-off when enhancing Fusarium head blight resistance of barley
… trophic lifestyles were conducted using barley BRI1 mutation lines, which display brassinosteroid (BR) insensitivity and a semi-dwarf phenotype. Interestingly, bri1 semi-dwarf lines did not display increased susceptibility to FHB. Additionally, bri1 mutation provided advantageous resistance to …

Protein phosphorylation regulation in Arabidopsis
… were observed. However, double mutants of kapp3/bri1-5 show increased sensitivity to brassinolide treatment. In vivo and in vitro experiments showed that KAPP interacts with BRI1 in a phosphorylation-dependent manner. These results suggest that KAPP is a negative regulator of the BRI1 signaling …

Brachypodium distachyon as a genetic model pathosystem to study resistance against fungal pathogens of small grain cereals
… of the main brassinosteroid (BR) receptor (BRI1) was characterized and validated. Other mutants defective in auxin or ET responsiveness and jasmonic acid (JA) biosynthesis were investigated. Results suggest that JA and BRI1 promote disease susceptibility. Finally, Chapter 5 uses a chemical …

A multiscale study of plasmodesmata: from channel ultrastructure to plant architecture
… in the phloem, and identify EMS-MUTAGENIZED BRI1 SUPPRESSOR 3 as a suppressor of restricted phloem unloading in lines that over-accumulate callose, a polysaccharide occluding plasmodesmata. The protein might specifically control correct folding of callose synthase enzymes within the …
