Jasmonic acid methyl ester induces xylogenesis and modulates auxin-induced xylary cell identity with NO Involvement [PDF]

open access: yes, 2019
In Arabidopsis basal hypocotyls of dark-grown seedlings, xylary cells may form from the pericycle as an alternative to adventitious roots. Several hormones may induce xylogenesis, as Jasmonic acid (JA), as well as indole-3-acetic acid (IAA) and indole-3 ...

Effect of medium-pH and MES on adventitious root formation from stem disks of apple [PDF]

open access: yes, 2008
We have examined the effect of medium-pH on rooting using 1-mm slices cut from stems of apple microshoots. Before autoclaving, the pH of the rooting medium was set at various pH values between 4.5 and 8.0. During autoclaving, the pH drifted in particular
