Aloe vera inhibits inflammation and adjuvant-induced arthritis. The authors' laboratory has shown that A. vera improves wound healing, which suggests that it does not act like an adrenal steroid. Diabetic animals were used in this study because of their poor wound healing and anti-inflammatory capabilities. The anti-inflammatory activity of A. vera and gibberellin was measured in streptozotocin...

We screened a phage display peptide library for peptidyl mimotopes of gibberellin against anti-bioactive gibberellin antibody. The peptides obtained were grouped into two homologous sequences and their binding to the antibody was put in competition with free GA(4) but not with GA(4) methylester, suggesting that the peptides behave as mimics of GA(4). As an application, the phage display peptide...

in order to investigate the characteristics of in vitro microtuberization of potato cv. agria in response to the two triazole anti-gibberellin, paclobutrazole and uniconazol, two independent experiment in five concentrations (0, 0.08, 0.16, 0.32, 0.64 mg/l) of each compound were carried out with four replications for each treatment in a completely randomized design. in this experiment percent o...

abstract in order to study of two hormones effects of gibberellin and benzyl adenine on (zantedeschia aethiopica cv.childsiana) pot plant characteristics, non dormant rhizomes dipped preplanting in gibberellin solution with concentrations including (0, 100, 200 and 500 ppm) and sprayed in two weeks once to flowering time with benzyl adenine solutions including (0, 100, 200 and 500 ppm). interac...

Gibberellins are phytohormones that regulate growth and development of plants. Gibberellin homeostasis is maintained by feedback regulation of gibberellin metabolism genes. To understand this regulation, we manipulated the gibberellin pathway in tobacco and studied its effects on the morphological phenotype, gibberellin levels and the expression of endogenous gibberellin metabolism genes. The o...

A homogenate from dwarf pea seedlings that had been treated with [(3)H]gibberellin A(1) was separated by Sephadex G-200 into two protein fractions, of high and intermediate molecular weight, with affinity for [(3)H]gibberellin A(1). Neither fraction bound [(3)H]gibberellin A(8), the only metabolite of [(3)H]gibberellin A(1) detected in significant quantity in extracts of pea seedlings. These pr...

We investigated floral initiation in the long-day monocot Lolium temulentum, strain Ceres, by culturing apices explanted from photoperiodically induced plants at various times after one inductive long day onto medium with, and without, gibberellin. Apices cultured on the first day after the inductive long day usually required gibberellin in the medium to initiate floral morphogenesis while apic...

Flowering of Nicotiana tabacum cv Xhanti depends on gibberellins because gibberellin-deficient plants, due to overexpression of a gibberellin 2-oxidase gene (35S:NoGA2ox3) or to treatment with the gibberellin biosynthesis inhibitor paclobutrazol, flowered later than wild type. These plants also showed inhibition of the expression of molecular markers related to floral transition (NtMADS-4 and N...
