Comparison of RNA expression in paravienal mesophyll (PVM) and palisade parenchyma (PP) cells.

ABSTRACT: The paraveinal mesophyll (PVM) of soybean leaves is a layer of laterally expanded cells sandwiched between the palisade and spongy mesophyll chlorenchyma. The vacuoles of PVM cells contain an abundance of a putative vegetative storage protein, VSP (α, β). VSP is is constitutively produced, but is up-regulated during sink limitation experiments involving flower, fruit, or vegetative bud removal. Soybean vegetative lipoxygenases (Vlx), consisting of 5 isozymes (Vlx, A-D), have been identified as potential storage proteins because they accumulate to high levels with experimental sink limitation and have been co-localized with VSP to the vacuoles of PVM cells. We re-investigated the sub-cellular locations of these enzymes with TEM immuno-cytochemistry. We employed laser micro-dissection to
