Mercury-induced Ethylene Formation and Abscission in Citrus and Coleus Explants.

Mercury vapor induces ethylene formation and abscission in Citrus and Coleus explants. Both responses are markedly greater in the absence of CO(2). The stimulation of these metabolically complex processes indicates that the action of mercury vapor is not consistent with the more popular conception of mercury toxicity. This was manifested in its complete failure to disturb respiratory gas exchan...

Ethylene-induced differential gene expression during abscission of citrus leaves

The main objective of this work was to identify and classify genes involved in the process of leaf abscission in Clementina de Nules (Citrus clementina Hort. Ex Tan.). A 7 K unigene citrus cDNA microarray containing 12 K spots was used to characterize the transcriptome of the ethylene-induced abscission process in laminar abscission zone-enriched tissues and the petiole of debladed leaf explant...

The Effects of pH, Ionic Strength, and Ethylene on the Extraction of Cellulase from Abscission Zones of Citrus Leaf Explants.

The solubility of cellulase extracted from the abscission zones of citrus leaf explants (Citrus sinensis L. Osbeck) in sodium phosphate buffer depends on the pH of the extracting solution and, to a lesser extent, on the ionic strength. By increasing molarity from 0.01 to 0.16, the solubility of cellulase increased from 51% to 89% at pH 6.1 and from 70% to 98% at pH 7. In all cases, residual cel...

Abscission of citrus leaf explants: no correlation with naphthaleneacetic Acid conjugation in the abscission zone.

The role of alpha-naphthaleneacetic acid (NAA) in the control of abscission in Citrus (Citrus sinensis L. Osbeck) leaf explants and its conjugation were studied in non-aged and 24-hour-aged explants. Dipping non-aged explants in 1.5 micromolar NAA for 15 minutes immediately after excision did not delay abscission whereas 150 micromolar NAA effectively delayed it. As incubation time was prolonge...
