Figure 6From: Developmentally distinct activities of the exocyst enable rapid cell elongation and determine meristem size during primary root growth in ArabidopsisThe root growth response of exocyst mutants to IAA and NPA. (A) IAA dose–response of exocyst mutant root growth was similar to Col-0, but different from auxin transport mutants aux1-7 and pin2-1. (B) Exocyst mutants, sec8-3 and exo84b, were slightly more sensitive to NPA at 3.16 and 10 μM compared to Col-0, whereas two auxin transport mutants were less sensitive.Back to article page
