Characterization of auxin conjugates in Arabidopsis. Low steady-state levels of indole-3-acetyl-aspartate, indole-3-acetyl-glutamate, and indole-3-acetyl-glucose.
It is shown here that IAA-aspartate Asp, Iaa-glutamate (Glu), and IAA -glucose (Glc) are present at low levels in Arabidopsis, and this results bring into question the physiological relevance of I AA-Asp accumulation in response to high concentrations of exogenous IAA.
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 fresh
Identification and quantification of IAA and IBA in Azospirillum brasilense-inoculated maize roots
Abstract Inoculation of maize seedlings with 107 colony forming units (cfu) of Azospirillum plant−1 significantly increased the root surface area 2 weeks after sowing as compared to non-inoculated
Indole-3-butyric acid in Arabidopsis thaliana
The results showed that IAA was present in higher concentrations than IBA, but both hormones seemed to show the same behaviour under the different experimental conditions, and differences were found in the mode of conjugation of the two hormones.
Biosynthesis of indole-3-acetic acid via the indole-3-acetamide pathway in Streptomyces spp.
Results indicate the presence of the IAM pathway (Trp-->IAM-->IAA) and the possible presence of additional pathways for IAA biosynthesis in Streptomyces.
Identification and seasonal changes of glucose, fructose and mannitol in relation to oil accumulation during fruit development in Olea europaea (L.)
Abstract The amounts of glucose, fructose and mannitol, the main sugars in olive fruits, were determined in ‘Kadesh’, ‘Uovo di Piccione’ and ‘Manzanillo’ which have 8, 15 and 20% oil, respectively,
Occurrence and in Vivo Biosynthesis of Indole-3-Butyric Acid in Corn (Zea mays L.).
The in vivo conversion of IAA to IBA and the characteristics of IBA formation in two different maize varieties of Zea mays L. (Hazera 224 and Inrakorn) were investigated.
Indole glucosinolate and auxin biosynthesis in Arabidopsis thaliana (L.) Heynh. glucosinolate mutants and the development of clubroot disease
A role for indole glucosinolates and IAN/IAA in relation to symptom development in clubroot disease is indicated.
Auxin-conjugate hydrolysis in Chinese cabbage: characterization of an amidohydrolase and its role during infection with clubroot disease.
Different auxin conjugates can be hydrolyzed at different developmental stages or under stress, and the increased free IAA content in clubroot-diseased roots of Brassicaceae can be due to either de novo synthesis or release of IAA from conjugate.
