Assay of photosynthetic efficiency in leaf chlorophyll of <i>GhGalT1</i> overexpression transgenic <i>Arabidopsis</i> seedlings.

<p>Nine-day-old <i>Arabidopsis</i> seedlings of <i>GhGalT1</i> transgenic lines, wild type and mutants growing on 1/2 MS without sugar (<b>A</b>) and with 1% sucrose (<b>B</b>). Fv/Fm: the maximal of photosynthetic efficiency. Error bars represent standard errors of three replicates. Asterisk represents significant difference (one asterisk: P value<0.05; two asterisk: P value<0.01) between the transgenic lines/mutant and wild-type by t-test. WT: wild type; GhGalT1oe-L1 and -L5: <i>GhGalT1</i> overexpression transgenic line 1 and 5; SALK043252 and SALK015338: two T-DNA insertion mutants.
