Auxin conjugates: their role for plant development and in the evolution of land plants.
TLDR
The function of auxin conjugates has been mainly elucidated by mutant analysis in genes for synthesis or hydrolysis and a possible function for conjugate inferred from these results, but there is increasing evidence of the occurrence of peptides and proteins modified by IAA. Expand
Indole-3-butyric acid in plant growth and development
TLDR
The role of IBA forcertain developmental processes in plants is discussed and somearguments presented that IBA is per se an auxin and does notact via the conversion to IAA. Expand
Arabidopsis glucosyltransferase UGT74B1 functions in glucosinolate biosynthesis and auxin homeostasis.
TLDR
Biochemical analyses demonstrate that recombinant UGT74B1 specifically glucosylates the thiohydroximate functional group, and promoter activity during plant development reveals expression patterns consistent with glucosinolate metabolism and induction by auxin treatment, providing complementary in vitro and in vivo evidence for a primary role of UGT 74B1 in glucosInolate biosynthesis.

The Plasmodiophora brassicae genome reveals insights in its life cycle and ancestry of chitin synthases
TLDR
The 25.5 Mb genome draft of P. brassicae is presented, developmental stage-specific transcriptomes and a transcriptome of Spongospora subterranea, the Plasmodiophorid causing powdery scab on potato are presented, and a protein (PbGH3) that can modify auxin and jasmonic acid is reported. Expand
Agrobacterium tumefaciens Promotes Tumor Induction by Modulating Pathogen Defense in Arabidopsis thaliana[W]
TLDR
It is suggested that crosstalk among IAA, ET, and SA balances pathogen defense launched by the host and tumor growth initiated by agrobacteria, whereas ET and auxin stimulate neovascularization during tumor formation. Expand
Indole-3-butyric acid in plants : occurrence, synthesis, metabolism and transport
Indole-3-butyric acid (IBA) was recently identified by GC/MS analysis as an endogenous constituent of various plants. Plant tissues contained 9 ng g−1 fresh weight of free IBA and 37 ng g−1 freshExpand
Analysis of indole-3-butyric acid-induced adventitious root formation on Arabidopsis stem segments.
TLDR
It is suggested that adventitious rooting in Arabidopsis stem segments is due to an interaction between endogenous IAA and exogenous IBA, and residual endogenous I AA is transported to the basal end of each segment, thereby inducing root formation. Expand
Elongation-related functions of LEAFY COTYLEDON1 during the development of Arabidopsis thaliana.
TLDR
LEC1 appears to be an integrator of various regulatory events, involving the transcription factor itself as well as light and hormone signalling, especially during somatic and early zygotic embryogenesis, and non-embryonic functions for LEC1 during post-germinative etiolation are suggested. Expand
Metabolism and Plant Hormone Action During Clubroot Disease
TLDR
A model is presented for how primary metabolism and secondary metabolism, including plant hormones, interact to induce clubroot formation in Brassicaceae plants. Expand
Induction of trehalase in Arabidopsis plants infected with the trehalose-producing pathogen Plasmodiophora brassicae.
TLDR
It is found that trehalose accumulated strongly in the infected organs and, to a lesser extent, in the leaves and stems of infected plants, and it is unlikely that tre Halase was induced by its substrate, but the induction of trehalase may be part of the plant's defense response and may prevent excess accumulation in the plant cells, where it could interfere with the regulation of carbon metabolism.
