Arabidopsis Type II Phosphatidylinositol 4-Kinase PI4Kγ5 Regulates Auxin Biosynthesis and Leaf Margin Development through Interacting with Membrane-Bound Transcription Factor ANAC078. [PDF]
PLoS Genetics, 2016 Normal leaf margin development is important for leaf morphogenesis and contributes to diverse leaf shapes in higher plants. We here show the crucial roles of an atypical type II phosphatidylinositol 4-kinase, PI4Kγ5, in Arabidopsis leaf margin ...

Auxin and nitric oxide control indeterminate nodule formation
BMC Plant Biology, 2007 Background Rhizobia symbionts elicit root nodule formation in leguminous plants. Nodule development requires local accumulation of auxin. Both plants and rhizobia synthesise auxin.

Lupeol Accumulation Correlates with Auxin in the Epidermis of Castor
Molecules, 2021 Lupeol, a natural lupane-type pentacyclic triterpene, possesses various pharmacological properties, and its production attracts attention. Significant quantities of lupeol are deposited on the castor aerial organ surface and are easily extractable as a ...

Induction and superinduction of auxin-responsive mRNAs with auxin and protein synthesis inhibitors.
Journal of Biological Chemistry, 1990 We have identified a class of small mRNAs (approximately 0.5 kilobases), referred to as small auxin-up RNAs (SAURs), that increases in abundance within minutes after auxin application to excised elongating hypocotyl sections of soybean. In this study, we present evidence that SAURs accumulate in the absence of auxin when protein synthesis is inhibited.

The effect of NGATHA altered activity in auxin signaling pathways within the Arabidopsis gynoecium
Frontiers in Plant Science, 2014 The four NGATHA genes (NGA) form a small subfamily within the large family of B3-domain transcription factors of Arabidopsis thaliana. NGA genes act redundantly to direct the development of the apical tissues of the gynoecium, the style and the stigma ...

Root System Patterning: Auxin Synthesis at the Root Periphery [PDF]
Current Biology, 2015 Plasticity in plant form is achieved through differential elaboration of developmental pre-patterns during postembryonic organ development. A new report links the output of the root clock, an oscillatory transcriptional pre-patterning mechanism, with cell-type-specific production of the plant hormone auxin, and identifies a downstream component ...

Azido Auxins: Synthesis and Biological Activity of Fluorescent Photoaffinity Labeling Agents [PDF]
Plant Physiology, 1981 Three auxin analogs, 4-, 5-, and 6-azido-3-indoleacetic acid (4-N(3)-IAA, 5-N(3)-IAA, and 6-N(3)-IAA) have been synthesized for use as fluorescent photoaffinity labeling agents. The pK(a) values of these compounds (4-N(3)-IAA, 4.67; 5-N(3)-IAA, 4.65; 6-N(3)-IAA, 4.66; all +/- 0.04) are experimentally indistinguishable from the pK(a) of 3-indoleacetic ...
