   2.6.1.96 | malfunction |
enzyme-deficient pop2 flowers accumulate GABA, and the growth of many pop2 pollen tubes is arrested, consistent with their in vitro GABA hypersensitivity. Some pop2 tubes continue to grow toward ovules, yet they are misguided, presumably because they target ectopic GABA on the ovule surface. Wild-type tubes decreased POP2 activity leads to increased levels of GABA throughout the ovule, coupled with aberrant growth and guidance of pop2 pollen tubes |

| 2.6.1.96 | physiological function |
inhibition of gamma-aminobutyrate-transaminase (GABA-T) of Brassica napus, using vinyl-GABA as a specific inhibitor reduces root growth by 44%. Inhibition is less severe when vinyl-GABA is associated with exogenous GABA and is not reduced with exogenous GABA alone. GABA level in root is not linked with the root length reduction. In root, vinyl-GABA-treatment causes a twofold increase in content of almost all amino acids, except for alanine whose content is 19fold higher than in control |

| 2.6.1.96 | physiological function |
the POP2 gene encodes a transaminase that degrades GABA and contributes to the formation of a gradient leading up to the micropyle, effect of GABA on pollen tube elongation in vitro |
