After about 20 days, hypocotyl cuttings from 20-day-old loblolly pine (Pinus taeda L.) seedlings rooted easily in the presence of the auxin indole-3-butyric acid (IBA), with roots forming directly from xylem parenchyma. In contrast, woody cuttings from 1-2-year-old hedged seedlings formed roots indirectly from callus tissue in 60-90 days, but IBA had little effect on rooting. Variation in rooti...

The InfiniBand Architecture (IBA) defines a switch-based network with point-to-point links that supports any topology defined by the user, including irregular ones, in order to provide flexibility and incremental expansion capability. Routing in IBA is distributed, based on forwarding tables, and only considers the packet destination ID for routing within subnets in order to drastically reduce ...

The diagnosis of Chagas' disease relies mostly on data provided by immunologic tests, but inconclusive results often require elucidation, especially in blood banks. When six different types of Trypanosoma cruzi epimastigote antigens were studied by an immunoblotting assay (IBA), a preserved protein antigen (Ag PP) was found to present the most interesting immunochemical features because of its ...

An experimental study was conducted at Students Experimental and Research Nursery: Department of Forestry, Range Management & Wildlife, University of Agriculture Faisalabad through which effect of growth hormone (IBA) on vegetative propagation of shisham (Dalbergia sissoo) was determined. The branch cuttings were prepared from one-year-old branches of resistant plus trees of shisham at UAF, hav...

Aims: Vitis vinifera is a grape species and native to the Mediterranean region and east to northern Iran. The present research was carried out in greenhouse conditions to study the effects of four concentrations of indole-3-butyric acid (IBA) (0; 2000; 4000; and 6000 mg/l) and three planting beds (agricultural soils, sandy, and mixture of agricultural soils and sand) on rooting grape cuttings i...

Plants have developed numerous mechanisms to store hormones in inactive but readily available states, enabling rapid responses to environmental changes. The phytohormone auxin has a number of storage precursors, including indole-3butyric acid (IBA), which is apparently shortened to active indole-3-acetic acid (IAA) in peroxisomes by a process similar to fatty acid b-oxidation. Whereas metabolis...

The induction and improvement of in vitro rhizogenesis of microshoots of Prosopis chilensis (Mol.) Stuntz and Nothofagus alpina (Poep. et Endl. Oerst.) were compared using Agrobacterium rhizogenes (Ar) versus indole-3-butyric acid (IBA) in the culture media. Microshoots of P. chilensis (1-2 cm length), coming from in vitro grown seedlings, were cultivated in a modified Broadleaved Tree Medium (...

Genetic evidence suggests that plant peroxisomes are the site of fatty acid beta-oxidation and conversion of the endogenous auxin indole-3-butyric acid (IBA) to the active hormone indole-3-acetic acid. Arabidopsis mutants that are IBA resistant and sucrose dependent during early development are likely to have defects in beta-oxidation of both IBA and fatty acids. Several of these mutants have l...

Dwarf hygro (Hygrophila polysperma) is an ornamental aquatic plant that changes its leaf colours to pinkish in high light. It is listed as a medicinal plant in medicinal plant lists of Indian states of West Bengal and Karnataka. It is also used as a screening tool for toxicities and a bioindicator to detect and control algae. The study reported in vitro adventitious shoot regeneration from leaf...
