The phytohormone auxin plays critical roles in the regulation of plant growth and development. Indole-3-acetic acid (IAA) has been recognized as major for more than 70 y. Although several pathways have proposed, how is synthesized plants still unclear. Previous genetic enzymatic studies demonstrated that both TRYPTOPHAN AMINOTRANSFERASE OF ARABIDOPSIS (TAA) YUCCA (YUC) flavin monooxygenase-like proteins are required biosynthesis IAA during development, but these enzymes were placed two...
The phytohormone auxin plays a central role in many aspects of plant growth and development. IAA is the most studied natural that possesses property polar transport plants. Phenylacetic acid (PAA) has also been recognized as for >40 years, but its development remains unclear. In this study, we show PAA have overlapping regulatory roles distinct characteristics auxins widely distributed vascular non-vascular Although biological activities are lower than those IAA, endogenous levels much...
Significance The plant hormone auxin controls many aspects of growth and development. It does so by changing the activity AUXIN RESPONSE FACTOR (ARF) proteins that recognize specific DNA elements in genes switch gene expression on or off. A major question biology is how these ARF bind unique sequences thus select which are regulated auxin. Here, authors systematically study architecture required for high-affinity binding proteins, auxin-dependent regulation Arabidopsis thaliana . This work...
IAA is a naturally occurring auxin that plays crucial role in the regulation of plant growth and development. The endogenous concentration spatiotemporally regulated by biosynthesis, transport its inactivation plants. Previous studies have shown metabolism to 2-oxindole-3-acetic acid (OxIAA) OxIAA-glucoside (OxIAA-Glc) may play an important homeostasis, but genes involved this metabolic pathway are still unknown. In study, we show UGT74D1 catalyzes glucosylation OxIAA Arabidopsis. By...
Auxin is the first discovered plant hormone and essential for many aspects of growth development. Indole-3-acetic acid (IAA) main auxin plays pivotal roles in intercellular communication through polar transport. Phenylacetic (PAA) another natural that does not show movement. Although a wide range species have been shown to produce PAA, its biosynthesis, inactivation physiological significance plants are largely unknown. In this study, we demonstrate overexpression CYP79A2 gene, which...
Abstract The Auxin Response Factors (ARFs) family of transcription factors are the central mediators auxin-triggered transcriptional regulation. Functionally different classes extant ARFs operate as antagonistic auxin-dependent and -independent regulators. While part evolutionary trajectory to present auxin response functions has been reconstructed, it is unclear how emerged, early diversification led functionally proteins. Here, we use in silico vivo analyses revisit molecular events that...

The large GTPase dynamin is strongly accumulated in the constricted area including midzonal microtubules of dividing cells. proline-rich domain (PRD) has been considered as a microtubule-binding domain. However, it remains unclear how PRD controls dynamin-microtubule interaction mitotic Here, we found that activity low dynamin-2. One mitosis-specific kinase activities to HeLa cells was identified cyclin B-Cdc2 kinase. phosphorylated at Ser(764) and/or Thr(766) and reduced PRD. These results...
