Figure 2. GNC and CGA1 expression alters chlorophyll content in the ahk2/3 cytokinin receptor mutant.

Figure 2

Both semi-quantitive PCR (A) and Real-time qRT-PCR (B) demonstrate that CGA1 is down regulated in the leaves of the ahk2/3 cytokinin receptor mutant while GNC expression is slightly increased. C) Chlorophyll content of 1778-gnc, ahk2/3 and gnc/ahk2/3 mutant lines compared to wild type (Wt-Col) plants at 3 weeks post germination (MEAN±SD, p≤.05, t-test). Image demonstrates that the triple mutant is of a similar size to ahk2/3 double mutant, but also has drastically reduced chlorophyll content.
