Effects of Brassinolide and IAA on Ethylene Production and Elongation in Maize Primary Roots
We examined the effects of brassinolide (BL) and/or an auxin (indole-3-acetic acid) on ethylene production and elongation in the primary roots of maize (Zea mays). When these two hormones were applied exogenously...

Ethylene and indole-3-Acetic Acid participate in the in-rolling and opening of carnation petal segments
We have examined the inward-rolling and outward-opening of petals from 90° stage carnation flowers (Dianthus charyophyllus L. cv. Pink Donor). Ethylene released from 2-chloroethylphosphonic acid (CEPA) induced in...

Dose-dependent effects of malformin A1 on IAA-induced ethylene production in mung bean (Vigna radiate L.) hypocotyl segments
Purified malformin A1 (cyclo-D-Cys-D-Cys-L-Val-D-Leu-L-lle), a cyclicpentapeptide toxin fromAspergillus niger, was applied to the hypocotyl segments of mung bean (Vigna radiata L.) seedlings to investigate its ro...

Brassinosteroids affect ethylene production in the primary roots of maize (Zea mays L.)
To better understand the physiological roles of brassinosteroids (BRs) in the primary roots of maize, we examined their effect on ethylene production. Exogenously applied brassinolide (BL; 10-9 to 10-7 M) increme...

Identification and bioavailability of a chromatin-binding peptide (Lunasin) from Korean Soybean
Lunasin is a novel peptide with great potential as a nontoxic chemopreventive drug. This compound might account for part of the anticancer effects reported from studies with soybean(Glycine max). We studied its i...

Action of malformin A1 on gravitropic curvature in primary roots of maize (Zea mays L.)
Malformins, a small family of cyclic pentapeptides, are active plant growth regulators isolated from the fungusAspergillus niger. We purified malformin A1 from the crude malformin A mixture, and studied its actio...

Effect of far infrared rays emitted from the calcined ceramics on ethylene production in mungbean hypocotyls
Ethylene production was measured in mungbean hypocotyls in the presence of far infrared rays emitted from ceramic powder using a gas chromatography. Both IAA-and 1-aminocyclopropane-1-carboxylic acid (ACC)-ind...

Effect of ethylene antagonists on auxin-induced inhibition of intact primary root elongation in maize (Zeamays L.)
Root elongation was measured in intact primary roots of maize(Zea mays L.) using a computerized root auxanometer. We examined the fact that root elongation was inhibited by auxin-induced ethylene production. Inhi...

Effect of auxin and ethylene on elongation of intact primary roots of maize (Zeamays L.)
We tested that the hypothesis that root elongation might be controlled by altering the level of ethylene in intact primary roots of maize(Zea mays L.). We measured root elongation in a short period using a comput...
