Cytosolic Acetyl-Coa Promotes Histone H3 Lysine 27 Acetylation In Arabidopsis, Chen Chen
Cytosolic Acetyl-Coa Promotes Histone H3 Lysine 27 Acetylation In Arabidopsis, Chen Chen
Electronic Thesis and Dissertation Repository
Acetyl-coenzyme A (acetyl-CoA) serves as a central metabolite in energy metabolism and biosynthesis. High level of acetyl-CoA can fuel the tricarboxylic acid (TCA) cycle to generate energy and store excess energy in fatty acids. Meanwhile, it also provides acetyl groups for protein acetylation, which normally occurs at the lysine or arginine residues. Acetylation regulates protein functions largely due to the change of total charges. Acetylation of histones, for example, can lead to loss of the interaction between histone and DNA, thus relaxing chromatin structure and potentially promoting gene expression. However, whether and how acetyl-CoA regulates plant chromatin remains unexplored. Here, …
Examining The Role Of Grp And Lik1 In Wall Associated Kinase (Wak) Perception Of Pectin In The Plant Cell Wall, Jack Ryan Mitchell
Examining The Role Of Grp And Lik1 In Wall Associated Kinase (Wak) Perception Of Pectin In The Plant Cell Wall, Jack Ryan Mitchell
Honors Projects
Wall associated kinases (WAKs) are cell membrane bound receptor kinases that bind pectin and pectin fragments (OGs).The binding of WAKs to pectin sends a growth signal required for cell elongation and plant development. WAKs bind OGs with higher affinity than native pectin and instead activate a stress response. Glycine rich proteins (GRPs) are secreted cell wall proteins of unknown function. Seven GRPs with 65% sequence similarity are coded on a 90kb locus of Arabidopsis chromosome 2. GRP3 and WAK1 have been shown to bind in vitro, but single null mutations have no discernible phenotype, suggesting that the GRPs are redundant. …
