Project name: Arabidopsis thaliana

Description: We characterized two independent insertional mutants of the AtEXO70A1 gene, encoding a subunit of the exocyst complex. Homozygous mutants exhibit a suite of phenotypic defects: polar growth of root hairs and stigmatic papillae is disturbed; organs are generally smaller; plants show loss of apical dominance and an indeterminate growth where instead of floral meristems new lateral inflorescences are initiated in a reiterative manner; exo70A1 mutants have dramatically reduced fertility. These results suggest that EXO70A1 is involved in cell and organ morphogenesis.Keywords: Expression profiling by arrayOverall design: 4 samples were used in this experiment
