TL;DR: It is suggested that phytoparasitic nematodes modulate the host’s developmental regulation of the vascular stem cells during gall formation, and this study deciphered the molecular mechanism of gall formation using RKN Meloidogyne incognita, and the model plant Arabidopsis thaliana.
Tryptophan auxotroph mutants suppress the superroot2 phenotypes, modulating IAA biosynthesis in arabidopsis.
TL;DR: Tryptophan auxotroph mutants seem to have a complete defect in Trp dependent IAA biosynthesis pathway, and it is suggested that the Trpdependent pathway is responsible for the normal root gravitropism.

MM31/EIR1 promotes lateral root formation in Arabidopsis.
TL;DR: It is proposed that MM31/EIR1 modulates lateralroot formation by regulating the IAA polar transport system, and that auxin transport from the shoot to the root regulates lateral root formation.

TL;DR: A Phalaenopsis variety harboring floral organs showing C class homeotic change is found, which strongly indicates the existence of active transposable element in Phalanxenopsis genome and may enable Phalaanopsis as a good material for molecular genetic analysis in Orchidaceae.
