From: Feedback inhibition of AMT1 NH4+-transporters mediated by CIPK15 kinase
NH4+-triggered CIPK15 mRNA accumulation. qRT-PCR analyses of AMT1;1 and CIPK15 mRNA levels in roots after over 10 h after addition of 1 mM NH4+. Levels were normalized to UBQ10 [mean ± SE for four independent experiments (each experiment n > 50, total n > 200)]. p, significant change for mRNA levels of AMT1;1 and CIPK15 at 1, 2, and 10 h compared to at 0 h (two-way ANOVA followed by Tukey’s post-test)
