Outline of Final Research Achievements |
(1) Analyses of positional cue formation by RTFL family: We cloned the homolog of RTFL from Marchantia polymorpha and constructed a series of transgenic lines. We also analyzed effects of a rice RTFL overexpression in Arabidopsis (Guo et al. 2015).(2) Holonic integration of cell proliferation and cell expansion: We cloned one of responsible genes of xs mutants that cancel compensated cell enlargement seen in an3 mutant.(3) Longitudinal leaflet formation: We proposed a new idea on the varation of direction of the leaflet formation along longitudinal axis of leaf primordia in Papaveraceae (Ikeuchi et al. 2013, 2014).(4) Mechanisms of pitcher leaves formation: We found that old theory on the mechanisms of pitcher leaf formation, that expect altered positioning of adaxial/abaxial borders in leaf primordia, was wrong; instead a new mechanisms was proposed for Sarracenia purpurea pitcher leaves (Fukushima et al. 2015).
