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.

Photoreception and photoresponses in the radish hypocotyl

Planta, 1977
In etiolated hypocotyls of Raphanus sativus L. the growth responses to continuous red, far-red and blue light have been distinguished on the bases of photoreceptive sites and regions of physiological response. Blue light appeared to retard a fairly mature stage of elongation, acting immediately and directly on the cells irradiated. Far-red light caused

Purification and structure of xyloglucan in pine hypocotyls

Phytochemistry, 1993
Xyloglucan was purified from water-soluble hemicelluloses extracted with 24% KOH from pine cell walls using ion-exchange chromatography and iodine precipitation. Linkage analysis showed that pine xyloglucan was highly substituted with 80% of the glucosyl residues substituted at position 6.

Xanthium pith and hypocotyl tissue in culture

Planta, 1978
A rapid method is described of obtaining callus tissue cultures from hypocotyls of vegetative and flowering Xanthium strumarium L. seedlings. The tissue is grown on Murashige and Skoog medium modified with 1 g/l casein hydrolysate and 5 mg/l each of kinetin and α-napthaleneacetic acid.

The effect of acetylcholine on hypocotyl elongation in soybean

Plant and Cell Physiology, 1980
Acetylcholine (Ach) and gibberellic acid (GA3) treatment of germinating seeds stimulated hypocotyl elongation in the soybean cultivar Otootan. Ethrel which evolves ethylene in plant tissues, markedly inhibited hypocotyl elongation. Ethrel also inhibited the Ach- and GA3-induced stimulation of hypocotyl elongation.

Study of Hypocotyl and Mesophyll Protoplasts

1983
Most of the plant protoplasts so far studied were generally isolated from leaf mesophyll tissue. The most notable disadvantage in using leaf tissue is the tedious method of removing epidermis from the leaves which again is not easy in all cases. But the protoplasts can “be easily isolated from any young hypocotyl or epicotyl segments by slicing them in

Testing the Viscoelasticity of Arabidopsis Hypocotyls

2018
The mechanical responses of hypocotyls, the embryonic stem of a plant between the cotyledons and root, are of interest because they can reveal insight into the timing and mechanosensitivity of growth hormones in plant growth and development. This independent study project aimed to develop a protocol for quantifying the viscoelastic responses of ...

Biosynthesis of cyanidin in buckwheat hypocotyls

Phytochemistry, 1979
Abstract Aminooxyacetate (AOA), an inhibitor of phenylalanine transamination and deamination in vitro, inhibits the light-induced formation of chlorogenic acid, leucoanthocyanin, rutin and anthocyanin (cyanidin glycosides) in buckwheat hypocotyls.

Hypocotyl hairs: an historical perspective

Australian Journal of Botany, 2009
The presence of distinctive hypocotyl hairs on young seedlings of some species has been known for some time, although largely ignored. A recent paper (Robinson et al. 2008) suggests that they may be of great ecological significance in the Australian shrub Melaleuca ericifolia. There is a scattered and little-known literature on this topic going back at
