Structure, gas chromatographic measurement, and function of suberin synthesized by potato tuber tissue slices.
The polymeric material (suberin) of the wound periderm of potato tuber slices was analyzed after depolymerization with LiAIH(4) in tetrahydrofuran or BF(3) in methanol with the use of thin layer chromatography, chemical modification, and combined gas-liquid chromatography and mass spectrometry. Fatty acids (C(16) to C(26)), fatty alcohols (C(16) to C(26)), octadec-9-ene-1, 18-dioic acid, and 18...
متن کاملCYP86A33-targeted gene silencing in potato tuber alters suberin composition, distorts suberin lamellae, and impairs the periderm's water barrier function.
Suberin is a cell wall lipid polyester found in the cork cells of the periderm offering protection against dehydration and pathogens. Its biosynthesis and assembly, as well as its contribution to the sealing properties of the periderm, are still poorly understood. Here, we report on the isolation of the coding sequence CYP86A33 and the molecular and physiological function of this gene in potato...
متن کاملPotato tuber tissue respiration & ventilation.
The purpose of this work is to compare gas movement through potato tuber tissue with the respiratory rate of such tissue and to assess possible oxygen deficiency as a factor in the limitation of respiration within the tissue. Argon 37 was used as a substitute for oxygen in most of the gas transfer experiments because it is easier to measure, its solubilities and diffusion coefficients are very ...
متن کاملTurnover Rates of Phosphate Esters in Fresh and Aged Slices of Potato Tuber Tissue.
In recent years, a number of studies have been miadle on the respiration of slices of potato tuber tissue (1, 6, 7, 8, 9, 11, 12, 13, 16, 17). \VXhen the slices or dlisks are freshly cut, they have a respiration rate sinmilar to that of the intact tuber. This tissue lhas been termed fresh tissue. \Vhen the fresh disks are kept by aerating them in distilled water or 10-4 Al CaSO4 at 00, the low ...
متن کاملActivation of protein synthesis in aging potato tuber slices.
LiCI-extraction of RNAs from isolated ribosomes, however, destroys the coding properties of mRNAs (as has been shown with cerebral mRNA; P. MANDEL, pers. comm.). Therefore separation of mRNAs from ribosomes was achieved by EDTA. If isolated ribosomes from intact potato tubers are dissociated into subunits and RNAs by EDTA, sucrose density gradient profiles show the presence of the 60Sand 40S-su...
