Phenylacetic hopanetetrol is a Frankia specific lipid present in vesicles. Phenylacetic acid (PAA) is known as an auxinomimetic, exhibiting the same effect on plant growth as indole acetic acid (IAA). We hypothesize that PAA, only bound by an ester l

The development of natural competence by bacteria in situ is considered one of the main factors limiting transformation-mediated gene exchanges in the environment. Ralstonia solanacearum is a plant pathogen that is also a naturally transformable bact

Degradation of protective tissues of coniferous needles (Abies alba Mill.) was examined by light and electron microscopy. Cuticle and hypodermis were destroyed at the beginning of the F1 stage, 1 year after needle fall. Hyphae from the superficial my
