Neither lysigenous nor just oil: demystifying myrtaceous secretory cavities.

Our findings support the hypothesis that technical artifacts may produce a lysigenous impression in oil glands. These tissue distortions must be considered when interpreting the development of this type of secretory structure. Moreover, the basic analyses of chemical constituents show for the first time that the glands of Neotropical Myrtaceae are potential reservoirs of some compounds previously reported as novelties for a few other myrtaceous species, such as flavonoids. As some of them are non-lipid compounds, the idea that glands are just oil repositories is no longer applicable. This article is protected by copyright. All rights reserved.
