Effect of a morphactin on growth, sex expression, fruit-set, and yield in Luffa acutangula

Effect of a morphactin on growth, sex expression, fruit-set, and yield in Luffa acutangula. Bisaria, A. K. (Dep. Bot., Hindu Coll., Moradabad, India). Can. J. Bot., 55(7), 752-6 (English) 1977. CODEN: CJBOAW. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemicals) A single foliar spray of a morphactin, fluorenol (I) [1689-64-1], was applied at a concn. of 1, 10, 100, or 1000 ppm to 6-week-old plants of ribbed gourd (Luffa acutangula), a monoecious cultivar. Growth of the main axis was only stimulated at 1 ppm and was increasingly inhibited at higher concns. I weakened apical dominance and increased the no. of lateral branches. The prodn. of pistillate and staminate flowers was increased and then decreased by I up to a concn. of 100 ppm. At the same concns. it also increased femaleness, no. of fruits, and therefore the yield. A drastic inhibition of total flowering, fruit-set, and therefore yield was recorded at 1000 ppm. Parthenocarpic fruits developed only at 100 and 1000 ppm.

Metabolism of alcohol and ketone by cytochrome P 450 oxygenase: fluoren-9-ol J fluoren-9-one

Metabolism of alcohol and ketone by cytochrome P 450 oxygenase: fluoren-9-ol J fluoren-9-one. Chen, Chiadao; Lefers, Roger C.; Brough, Eda Lee; Gurka, David P. (Med. Sch., Northwestern Univ., Chicago, IL 60611, USA). Drug Metab. Dispos., 12(4), 421-6 (English) 1984. CODEN: DMDSAI. ISSN: 0090-9556. DOCUMENT TYPE: Journal CA Section: 4 (Toxicology) Fluoren-9-ol (I) [1689-64-1] and fluoren-9-one (II) [486-25-9] were interconverted by an oxidoreductase(s) present in liver microsomal prepns., using pyridine nucleotides as cofactors. I could also be oxygenated to II by microsomes and NADPH with O. This oxygenation was inhibited by SKF 525-A and CO, suggesting the involvement of cytochrome P 450 oxygenase [9038-14-6]. Using highly purified P 450 oxygenase components, I was oxygenated by the complete system to II. Exclusion of cytochrome P 450 or its reductase resulted in no oxygenation. Dilauroylglyceryl-3-phosphorylcholine was without effect on the reaction. II, on the other hand, was reduced to I by NADPH-cytochrome P 450 reductase [9039-06-9] and NADPH. Thus, other alcs. and carbonyl compds. are similarly metabolized.
