Trehalose Toxicity in Cuscuta reflexa: CORRELATION WITH LOW TREHALASE ACTIVITY.
A toxic effect of alpha,alpha-trehalose in an angiospermic plant, Cuscuta reflexa (dodder), is described. This disaccharide and its analogs, 2-aminotrehalose and 4-aminotrehalose, induced a rapid blackening of the terminal region of the vine which is involved in elongation growth. From the results of in vitro growth of several angiospermic plants and determination of trehalase activity in them,...
متن کاملTrehalose Toxicity in Cuscuta reflexa: SUCROSE CONTENT DECREASES IN SHOOT TIPS UPON TREHALOSE FEEDING.
Trehalose, an alpha,alpha-diglucoside, induced a rapid blackening and death of shoot tips of Cuscuta reflexa (dodder) cultured in vitro. The onset of toxic symptom was delayed if any of the several sugars which support the in vitro growth of Cuscuta was supplied with trehalose. The rate of trehalose uptake or its accumulation in the tissue was not affected by sugar cofeeding. The levels of tota...
متن کاملTrehalose Toxicity in Cuscuta reflexa: Cell Wall Synthesis Is Inhibited upon Trehalose Feeding.
alpha,alpha-Trehalose induced a rapid blackening of the terminal 2.5-centimeter region of excised Cuscuta reflexa Roxb. vine. The incorporation of radioactivity from [(14)C]glucose into alkali-insoluble fraction of shoot tip was markedly inhibited by 12 hours of trehalose feeding to an excised vine. This inhibition was confined to the apical segment of the vine in which cell elongation occurred...

متن کاملCuscuta reflexa and Carthamus Oxyacantha: potent sources of alternative and complimentary drug
The present study was designed to evaluate the biological potential of Cuscuta reflexa and Carthamus oxyacantha. The ethanolic crude extract (C. reflexa; 9.1% and C. oxyacantha; 10.4%) was partitioned with different solvents at pH 3.0, 9.0 and 7.0. Phytochemical study showed that n-hexane fractions were rich source of terpenoids and ethyl acetate fractions were phenolic in nature while chlorofo...
