the aim of this research was to evaluate the influence of rooting cofactors including hydrogen peroxide, boric acid and thiamine along with indole-3-butyric acid (iba) on rooting of olive cuttings cv. rashid in autumn 2007 and spring 2008. the study was carried out as a factorial experiment in a completely randomized design (crd) with three replications, and five cuttings in each replication. r...

Peroxisomes are important organelles in plant metabolism, containing all the enzymes required for fatty acid beta-oxidation. More than 20 proteins are required for peroxisomal biogenesis and maintenance. The Arabidopsis pxa1 mutant, originally isolated because it is resistant to the auxin indole-3-butyric acid (IBA), developmentally arrests when germinated without supplemental sucrose, suggesti...

In this study, the effects of IBA and cinnamic acid applications on rooting black mulberry cuttings taken from trees grown in Tokat were treated. 6000 ppm Indole Butyric Acid (IBA), IBA+100 (CA), 100 with control which no application was applied July, September, November January periods. The kept during 60 days beds containing perlite heated bottom. highest ratio (48.3%) average root number (3....

The role of the auxins indole-3-acetic acid (IAA) and indole-3-butyric acid (IBA) and of the auxin-interacting phytohormone ethylene, on the ectopic formation of primary xylem (xylogenesis in planta) is still little known. In particular, auxin/ethylene-target tissue(s), modality of the xylary process (trans-differentiation vs. de novo formation), and the kind of ectopic elements formed (metaxyl...

Multiple shoots were induced from leaf explants of Lycopersicon esculentum cultivar MicroTom, within 20-25d, on MS medium supplemented with 8.9 microM benzylaminopurine (BAP)+1.14 microM indole-3-acetic acid (IAA). For rooting, elongated microshoots were excised and transferred onto MS medium supplemented with 4.9 microM indole-3-butyric acid (IBA). Well-developed roots and flower raceme were o...

Genetic evidence suggests that indole-3-butyric acid (IBA) is converted to the active auxin indole-3-acetic acid (IAA) by removal of two side-chain methylene units in a process similar to fatty acid beta-oxidation. Previous studies implicate peroxisomes as the site of IBA metabolism, although the enzymes that act in this process are still being identified. Here, we describe two IBA-response mut...

Reactive oxygen species and redox signaling undergo synergistic and antagonistic interactions with phytohormones to regulate protective responses of plants against biotic and abiotic stresses. However, molecular insight into the nature of this crosstalk remains scarce. We demonstrate that the hydrogen peroxide-responsive UDP-glucosyltransferase UGT74E2 of Arabidopsis thaliana is involved in the...

Clerodendrum pholomidis is an important medicinal plant of Lamiaceae. Leaves, internode and petiole explants were cultured on Murashige and Skoog (MS) medium supplemented with combinations of 2, 4-dichlorophenoxy acetic acid (2, 4-D), kinetin (kn) and indole-3 butyric acid (IBA). Leaf explants formed clusters of globular somatic embryos directly from epidermal cells within 12-15d when cultured ...

In this study the effect of growth regulators in different concentrations were tested for shoot and root development micropropagation pomegranate with nodal explants. The explants collected morning, third node from tip. healthy plants which authenticated. For MS media was supplemented alpha-naphthalene acetic acid (NAA), indole-3-butyric-acid (IBA), 6-benzyl aminopurine (BAP) kinetin their comb...
