Hexagonal tubular structures in sieve tubes of apple leaves


, : Hexagonal tubular structures in sieve tubes of apple leaves. Phytopathology 65(6): 660-663

Long, slightly curved tubular structures with a hexagonal cross-section and grouped into honeycomb arrangements were found in the sieve tubes of leaves from 8 different apple cvs. They were present in healthy control trees that had been indexed for, and found to be free from, known apple viruses, in trees infected with chlorotic leaf spot virus, and in trees that showed some witches' broom symptoms of the foliage.
