Research Project: FUNCTIONAL GENOMICS OF PLANT ARCHITECTURE

Location: Plant Gene Expression Center Albany_CA

Project Number: 5335-21000-038-00
Project Type: Appropriated

Start Date: Oct 01, 2010
End Date: Jul 15, 2013

Objective:
1. To identify additional components of the CLAVATA meristem signal transduction pathway. [NP 301, C 4, PS 4A] 2: To characterize the role of microRNAs and their target genes in regulating Arabidopsis shoot meristem activity. [NP 301, C 4, PS 4A] 3: To determine the function of the Arabidopsis BOP1 and BOP2 genes in regulating shoot apical meristem activity and leaf development. [NP 301, C 4, PS 4A] 4: To develop and test hypotheses to determine how knowledge of plant architectural genes in Arabidopsis can be applied to crop plants. [NP 301, C 4, PS 4A]

Approach:
Identify, isolate and characterize genes that regulate plant architecture in model systems and agriculturally important crops by 1) using a sensitized genetic screen to uncover novel components of the Arabidopsis thaliana CLAVATA stem cell signaling pathway; 2) determining the role of a small regulatory RNA and its five target genes in regulating stem cell maintenance during development; 3) analyzing the function of the BOP1 and BOP2 genes in regulating stem cell activity and leaf formation; and 4) developing and testing hypotheses on how knowledge of plant architectural genes in Arabidopsis can be applied to crop plants through the identification and functional analysis of orthologous genes.
