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 ...

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 ...

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

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.

Photosensory mechanisms in the lettuce seedling hypocotyl

Planta, 1969
A number of differences in the responses of 'Great Lakes' lettuce seedlings to blue and far-red light indicate that more than one photo-sensitive pigment is involved in the photo-inhibition of hypocotyl elongation under 'highenergy' conditions. In far-red light the inhibitory effect is restricted to young seedlings and is of limited duration; after 24 ...

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.

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.

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.

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

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.
