- AUXIN is a plant hormone which is involved in various physiological processes of plants.
- AUXIN is involved in
formation of the serrated edges of leaves
auxin helps in the primary morphogenesis of leaves
eg : Arabidopsis thaliana
- AUXIN is involved in
morphogenesis of the lateral root
ROOT SYSTEM unceasingly branch and form lateral roots , AUXIN acts as a local instructive signal and as a morphogenetic trigger.
- AUXIN is involved in
cell fate specification
AUXIN plays an important role in WUS expression, which is essential for embryonic stem cell fate determination
eg : Arabidopis
- AUXIN is involved in
specification of the apical-basal axis
local auxin sources orient the apical- basal axis
eg : Arabidopis

Question 1 Auxin transport Not yet answered Points out of 1.00 Flag question Select one: O a. Is polar, whereby auxin travels from shoot tips down the plant towards the roots. b. Produces a gradient of auxin required to establish organ formation and phototropic responses. c. Auxin is at highest concentrations, near its sources, like the apical meristems O d . Directionality of auxin movement (conferring polarity) is conferred by basally localized efflux carriers called PIN proteins e. All of...
