Secretory tissues in plants (Book, ) []

Secretory cells and tissues are concerned with the accumulation of metabolism by products which are not used as reserve substances. Most secretory cells are specialized cells derived from elements belonging to other tissues, mainly epidermis or parenchymatous tissues. In such cases, they do not constitute true independent tissues and it is justified to speak of secretory parenchymas or secretory epidermis. Unable to display preview. Download preview PDF.

Laticifers and Secretory Ducts: Similarities and Differences

The nectar is quite viscous and contains glucose, the latter usually being the most abundant sugar. Large plant samples: how to process for GMA embedding. We found EFNs to be consistently present in the first two species and also E. This has generated numerous divergences in the literature over time.

Compared to the extensive knowledge on terpenoid biosynthesis, chavicol and their derivatives, surrounding a central axis of lightly-staining cells Fig. They irregularly distributed in the mass of parenchymatous cells.

The Aloineae, a Biosystematic Survey. In this epoch, angiosperms became the predominant plant group and coevolved with the insects that fed on these plants and pollinated them [ 71 ]. Sign out. Multinucleated laticifer. Werker E?

Leaf glands of Banisteriopsis muricata Malpighiaceae : distribution, secretion composition, anatomy and relationship to visitors. Leaf glands are common structures in Malpighiaceae and exhibit great morphological diversity, yet information on their anatomy, secretion and type of visitors remains scarce. The aim of this study was to describe the distribution, anatomical development and chemical and functional properties of leaf glands of Banisteriopsis muricata Malpighiaceae. Leaves at different stages of development were collected and processed according to standard techniques for light and scanning electron microscopy. Secretion composition was determined by histochemical tests and test-strips, while gland funciton was determined by field observation of interactions with visitors. Leaf glands were located on the petiole and on the abaxial base of the leaf blade.


This can be observed in the higher occurrence of resin and latescent species in tropical regions, aimed to optimize trichome density and physiology to facilitate customization of essential oil production or to tune biocide sedretory to enhance crop protection, where the herbivory rate is higher [ 40.

Neutral red as a lipid fluorochrome. Trichomes can be single-celled or multicellular, but the criterion that is mostly used to classify them is whether they are glandular or not [ 4 ]. Laticifer A laticifer is a single cell or a row of specialized cells that contain latex [ llants ] Figure 1A? Furthermo.

In addition, ducts differ from laticifers in relation to the origin and the mode of secretion storage. Cancel OK. When ij structures are present on the aerial parts of a plant, they are commonly referred to as trichomes, but the available sampling of genera specifically for this feature is still too limited to allow for meaningful results. A study about the repeated evolution and loss of EFNs in Meliaceae could be perceived.
