(Submitter supplied) After four weeks the primary roots were cut off from the seedlings. The hypocotyl cuttings were treated in Hoagland nutrient solution at pH 5.8 containing 1.23 mM indole-3-butyric acid(IBA) for six hours then transferred to Hoagland nutrient solution lacking IBA. The hypocotyls were harvested at the following time points: day o,3,6,9,12 and 33. Keywords: time-course

Analysis of hypocotyls treated with auxin to induce adventitious root formation. Hypocotyls were harvested at day 0, day 3 (cell expansion), day 6 (when root primordia are formed), day 9 (when root meristems are formed), day 12 (when roots are fully developed), and day 33 (root elongation).

(Submitter supplied) The significant morphological differences observed during embryo development in angiosperms and gymnosperms are expected to be the result of a differential control of gene expression. We used a loblolly pine (Pinus taeda) cDNA microarray to analyze global transcriptional changes along zygotic embryogenesis in maritime pine (Pinus pinaster). A time-course analysis of the data obtained from the five embryo developmental groups used in this study led to the identification of 4,645 genes whose expression varied along P. more...

(Submitter supplied) Plants initially undergo a period of vegetative development, in which it produces leaves from shoot apical meristem (SAM) and roots from the root apical meristem. Later in development, the SAM undergoes a change in fate and enters reproductive development called as floral transition, producing flowers and seeds. Our understanding of the molecular and genetic mechanisms that underlie reproductive development in plants has increased tremendously in the past decade, essentially through the work on Arabidopsis. more...

(Submitter supplied) Indica rice seedlings of IR64 variety were grown hydroponically for 7-days in a culture room with a daily photoperiodic cycle of 14h light and 10h dark. Seedlings were incubated in 0.1% dimethyl sulfoxide (control) or 50 micromolar solutions of indole-3-acetic acid (IAA treatment) and benzyl aminopurine (BAP treatment) for 1h and 3h. Equal amounts of 1h and 3h samoles were pooled for each treatment before RNA isolation. more...

(Submitter supplied) Global transcriptional analysis of loblolly pine (Pinus taeda L.) is challenging due to limited molecular tools. PtGen2, a 26,496 feature cDNA microarray, was fabricated and used to assess drought-induced gene expression in loblolly pine propagule roots. Statistical analysis of differential expression and weighted gene correlation network analysis were used to identify drought-responsive genes and further characterize the molecular basis of drought tolerance in loblolly pine.

(Submitter supplied) Despite the major physiological dissimilarities between roots and their tips, differences in their gene expression profiles remain largely unexplored. In this research, the transcriptome of rice (Oryza sativa L. subsp. Japonica) mature root tissue and root tips was monitored using mRNA-Seq at 2 time points. Almost 50 million 76 bp reads were mapped onto the rice genome sequence, differential expression patterns between tissues and time points were investigated and at least 1,006 novel transcriptionally active regions (nTARs) were detected to be expressed in rice root tissue. more...

(Submitter supplied) The effects of mercury (HgCl2) on barley (Hordeum vulgare L.) growth, physiological traits and gene expression profiles were studied. The shoot to root ratio was decreased in the two levels of HgCl2 (500 and 1000 μM) assayed, which was related primarily with decreases in shoot dry weight. Moreover stomatal conductance was limited and leaf carbon isotope discrimination decreased. Therefore water uptake limitations seem to be an important component of barley responses to HgCl2. more...

(Submitter supplied) Adventitious roots (AR) develop from tissues other than the primary root, in a developmental process physiologically regulated by phytohormones. Adventitious roots provide structural support and contribute to water and nutrient absorption, and are critical for commercial vegetative propagation of several crops. Here we quantified the number of AR, root architectural traits and root biomass in cuttings from a pseudo-backcross population of Populus deltoides and Populus trichocarpa. more...
