Key components of photosynthetic capacity are increased in 35S::ATHB17 linesSample means ±SE are shown for leaf SPAD, percentage transmission of PAR, and estimates of V c,max and J max. Data were collected on at least five replicate plants for the empty-vector control and two 35S::ATHB17 lines. The means of each data set collected for the two 35S::ATHB17 lines were significantly different from the control line (P <0.05; two-tailed Student’s t-test).
