Gravistimulation enhanced balance between initiation and development. Mikaël Lucas Yann Guédon Christian Jay-Allemand Christophe Godin Laurent Laplaze 10.1371/journal.pone.0003673.g010 https://plos.figshare.com/articles/figure/_Gravistimulation_enhanced_balance_between_initiation_and_development_/586977 <p>(A) Initiation density and emerged lateral root density were scored for plants gravistimulated according to the gravistimulation protocol presented in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0003673#pone.0003673-Lucas1" target="_blank">[15]</a>. The results are given for primordia located in gravistimulated zones. Measurements were normalized in regard to the emergence density of non-gravistimulated plants. Each data point corresponds to a set of more than 20 seedlings. Non-gravistimulated Col-0 seedlings were used as a control group. (B) Emergence of lateral roots in gravistimulated roots. White bar: emerged lateral root percentage. Gray bar: non-emerged primordia percentage. Non gravistimulated Col-0 seedling were used as a control. (C) Distribution of primordia developmental stages for the 24 h time between gravistimulation treatment. White bar: primordia appearing and developing between gravistimulation (n = 72). Black bar: primordia appearing and developing in root turns (n = 373). (D) Initiation and emergence densities predicted by the mechanistic model with the added hypothesis of a drop of ET under gravistimulation.</p> 2008-11-19 01:56:17 enhanced initiation
