indole 3 butyric acid/pinus

Mature zygotic embryos of 24 genotypes of loblolly pine (Pinus taeda L.) were used as explants to establish an adventitious shoot regeneration system through somatic organogenesis. Callus formation frequencies of 18.2 (genotype 11-1103) -77.7% (genotype 7-100) have been induced from mature zygotic

Adventitious buds were induced from organogenic callus derived from mature zygotic embryos of three lines (E-311, E-440, and E-822) of loblolly pine (Pinus taeda L.) within 27 weeks of culture. The influence of cytokinins, silver nitrate, and low-temperature treatment on the differentiation of

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

A plant regeneration system through multiple adventitious shoot differentiation from callus cultures has been established in slash pine (Pinus elliottii). Influences of seven different basal media on callus induction, adventitious shoot formation, and rooting were investigated. Among the different

We studied the ability of the ectomycorrhizal (ECM) fungi, Pisolithus tinctorius (Pers.) Coker and Couch and Paxillus involutus (Batsch) Fr. (Strain H), to produce indole-3-acetic acid (IAA) and to affect the formation and growth of roots on Scots pine (Pinus sylvestris L.) hypocotyl cuttings in

Differential display reverse transcription-polymerase chain reaction was used to detect the induction of gene expression during adventitious root formation in loblolly pine (Pinus taeda) after treatment with the exogenous auxin indole-3-butyric acid. A BLAST search of the GenBank database using one

The ecology and physiology of ectomycorrhizal (EcM) symbiosis with conifer trees are well documented. In comparison, however, very little is known about the molecular regulation of these associations. In an earlier study, we identified three EcM-regulated Pinus expressed sequence tags (EST), two of

Mature zygotic embryos from three seed sources of loblolly pine were cultured on callus induction medium containing 10 mg l^-1 α-naphthaleneacetic acid, 4 mg l^-1 benzyladenine (BA), 400 mg l^-1 casein hydrolysate, and 400 mg l^-1 glutamine for 6 weeks.

Clonal propagation of Virginia Pine (Pinus virginiana Mill.) was achieved by organogenesis on cotyledon explants. The influence of several cytokinins and abscisic acid on adventitious shoot production from cotyledon explants was investigated. Benzyladenine was more effective in shoot induction than

A field experiment was conducted using a 3 × 3 orthogonal regression design to explore the growth promotion of one-year-old Yunnan pine seedlings (Pinus yunnanensis Franch.) in response to foliar application of IAA (indole-3-acetic acid) at rates of 0, 200 and 400 mg·L(-1) and IBA (indole-3-butyric

In order to investigate the gene expression pattern during adventitious root development, RNA of Pinus contorta hypocotyls, pulse-treated with the auxin indole-3-butyric acid and harvested at distinct developmental time points of root development, was hybridized to microarrays containing 2,178 cDNAs
