Abstract:
:Sieve tube "slime" is probably fibrillar as suggested by other workers. The granular material seen in electron micrographs of sieve tubes "fixed" with potassium permanganate is mostly a precipitate produced by the reaction of the permanganate with the sieve tube contents, particularly with sucrose, and with reagents used in the fixing, dehydrating and embedding process. Potassium permanganate is not therefore a good fixative for the electron microscopy of sieve tube contents. Neither is it suitable for the study of fine structure in vacuoles or vesicles containing precipitable solutes in other kinds of cells nor for examining the fine structure of their ground cytoplasm.

PLANTA文献大全abstract:MAIN CONCLUSION:For the first time, a plant (rice) translin was characterized. The rice translin protein, which was octameric in native state, bound efficiently to single-stranded DNA and RNA. Translin, a DNA-/RNA-binding protein, is expressed in brain, testis and in certain malignancies. It is involved in chromosomal ...
