Gibberellins and auxin regulate soybean hypocotyl elongation under low light and high-temperature interaction.

Physiologia Plantarum : An International Journal for Plant Biology, 2020
Soybean is an important oilseed crop grown globally. However, two examples of environmental stresses that drastically regulate soybean growth are low light and high temperature.

Reactive oxygen species regulate auxin levels to mediate adventitious root induction in Arabidopsis hypocotyl cuttings.

Journal of Integrative Plant Biology, 2020
Adventitious root (AR) formation from leafy stem cuttings is critical for breeding of many forest and horticultural species. In addition to the plant hormone auxin, wound-induced signaling caused by the cutting excision is also essential for AR ...

Auxin-regulated gene expression in intact soybean hypocotyl and excised hypocotyl sections

Planta, 1984
A library of complementary DNA (cDNA) clones has been prepared from polyadenylated RNA (poly(A)(+)RNA) from auxin (2,4-dichlorophenoxyacetic acid)-treated soybean (Glycine max (L.) Merr. cv. Wayne) seedlings. Using differential hybridization, four clones were selected as auxin-responsive, and characterized. The levels of the RNA sequences homologous to

KINEMATICS OF HYPOCOTYL CURVATURE

American Journal of Botany, 1978
Time lapse photographs were analyzed for curvature, κ, of the plumular hook as a function of distance from the apex, s, of seedlings of lettuce. Lactuca sativa cv ‘Grand Rapids,‘ during hook maintenance (red light) and hook opening (white light). Curvature of the inner edge of the photographic projection of the hook increases from 0.14 mm–1 near the ...

Role of auxinic herbicide-induced ethylene on hypocotyl elongation and root/hypocotyl radial expansion

Pest Management Science, 2000
Effects of auxinic herbicides on growth/development, ethylene biosynthesis and gene expression were studied in Sinapis arvensis as well as wild type, auxin-resistant and ethylene-insensitive lines of Arabidopsis thaliana. Expansion of the radius of the root/hypocotyl and inhibition of root and hypocotyl elongation were observed in seedlings of S ...

The ELF4–ELF3–LUX complex links the circadian clock to diurnal control of hypocotyl growth

Nature, 2011
The circadian clock is required for adaptive responses to daily and seasonal changes in environmental conditions. Light and the circadian clock interact to consolidate the phase of hypocotyl cell elongation to peak at dawn under diurnal cycles in ...

An apple B-Box protein MdBBX37 modulates anthocyanin biosynthesis and hypocotyl elongation synergistically with MdMYBs and MdHY5.

Plant and Cell Physiology, 2019
As an important environment factor, light affects plant growth and development throughout life. B-BOX (BBX) proteins play key roles in the regulation of light signaling.

Auxin carriers in membranes of lupin hypocotyls

Planta, 1986
The pH-driven accumulation of [(3)H]indolyl-3-acetic acid (IAA) has been found to occur in membrane vesicles of lupin (Lupinus albus L.) hypocotyls. Most of this association of auxin with membranes is very sensitive to osmotic shock, high concentrations of permeable weak acids, incubation at 20° C for 20 min and to some ionophores.

INITIATION OF NUTATION IN SUNFLOWER HYPOCOTYLS

1981
Publisher Summary This chapter discusses the initiation of nutation in sunflower hypocotyls. If, prior to the onset of nutating activity, one could see random walk type movements by the epicotyl that in time grow large enough to elicit a gravitropic response with overshoot, then one should interpret this as additional support for the validity of ...
