Tryptophan independent auxin biosynthesis
WebDiffusates from flower buds, flower fruits, and scape segments, and extracts of flower stalks of Narcissus pseudonarcissus contain an auxin active in the Avena geo-curvature test. The auxin behaved like indole-3-acetic acid (IAA) in thin-layer chromatography (TLC) with neutral and basic solvents on different adsorbents. After TLC, the auxin of the extracts showed … WebThe phytohormone auxin regulates plant development, and the tryptophan (Trp)-dependent pathway has been extensively uncovered in auxin biosynthesis. The exciting discovery by …

WebYUCCA protein participates in a key rate-limiting step in the tryptophan-dependent pathway for auxin biosynthesis and is involved in numerous processes during plant development. In this study, the genomic and cDNA sequences of three TaYUC10 homoeologous genes were isolated. These sequences showed a very high conservation in coding region and the … WebJul 1, 2016 · Auxin biosynthesis Two major pathways for IAA biosynthesis have been proposed in plants tryptophan (Trp)-independent Trp-independent IAA …
WebIts biological functions are adjusted by modulating biosynthesis, conjugate formation, and polar transport and distribution. Several tryptophan-dependent and -independent auxin biosynthetic pathways have been proposed. Recent studies have shown that a few flavin monooxygenase enzymes contribute to the tryptophan-dependent auxin biosynthesis. WebThe presence of auxins in soil may have an ecological impact affecting plant growth and development. A rapid and simple colorimetric method was used to assess California soils …
WebAbstract Indole-3-acetic acid (IAA) is the most abundant naturally occurring auxin. Plants produce active IAA both by de novo synthesis and by releasing IAA from conjugates. This …
