This sequence begins with the chlorophyll parenchyma, phloem, epidermis, bundle sheath
parenchyma, and, as the least digestible tissues, the xylem and sclerenchyma (HANNA et al.
In most Lychnophorinae species, the vascular bundles are attached to the epidermis on both faces through bundle sheath
A set of microdissectors is used to dissect the bundle sheath
and isolate the nerve branches from the adjacent vessels (Figure 1).
Vascular bundles are lined in rows and parenchymatic bundle sheath
is around of vascular bundles.
Small and medium-sized veins are immersed in the mesophyll and present endodermis (bundle sheath
In both grass species the injury mainly occurred to the chlorenchyma, which radiates around the bundle sheath
. It was also possible to observe that the parenchymatic sheath was affected in the signal grass.
 by the distance in transverse section between the outer edges of the bundle sheath
cells, adjacent to the two metaxylem vessels.
Prof Karpinski and his team found that when light triggered a chemical reaction in one leaf cell, it kicked off a "cascade" of events and that this was immediately signalled to the rest of the plant via a specific type of cell called "bundle sheath
2) with 2 or 6 subsidiary cells around guard cells in Astrocaryum, 4 in Hexopetion (11-13); (ii) chlorenchyma with palisade cells composed of short cells in Hexopetion and of long cells in Astrocaryum (61-62); (iii) fibers of bundle sheath
The vascular bundles of C4 plants are surrounded by a group of cells called bundle sheath
[C.sub.4] plants have succeeded in eliminating photorespiration by splitting the reactions of photosynthesis between two types of cells, mesophyll cells (MC) and bundle sheath
cells (BSC) (Kranz anatomy).
