EURēCA: Exhibition of Undergraduate Research and Creative Achievement
Flowers are composed of four floral organ types: sepals, petals, stamens, and a pistil. In Arabidopsis thaliana, the ERECTA family leucine rich repeat receptor like kinases (LRR-RLKs) have been shown to regulate plant morphology. Epidermal Patterning Factor-Like (EPFL) genes encode for small secretory proteins that are ligands for ERECTA Family (ERf) receptors. It is suspected that EPFL’s act as a signal to coordinate proper lateral organ number, patterning, and spacing. ERf mutants have significant defects in flower development, including difficulty forming anther lobes and pistils, yet little is known about how individual EPFL ligands contribute to ERf signaling. In order …

Plasmodesmata (PD) are pores that traverse plant cell walls, providing a route for intercellular trafficking of essential metabolites, nutrients, and signaling molecules between adjacent plant cells, thereby aiding communication. The increased size exclusion limit 2 (ise2) mutant of Arabidopsis thaliana has an increased abundance of branched PD, as well as a greater flux of intercellular trafficking. A search for proteins that interact with ISE2 identified THIOGLUCOSIDE GLUCOHYDROLASE 2 (a myrosinase). A. thaliana also encodes a second, closely-related myrosinase, TGG1. Myrosinases are enzymes that catalyze the hydrolysis of glucosinolates, a type of secondary metabolite that are amino acid derivatives. The breakdown …
