palisade mesophyll[‚pal·ə′sād ′mez·ə‚fil] (botany) A tissue system of the chlorenchyma in well-differentiated broad leaves composed of closely spaced palisade cells oriented parallel to one another, but with their long axes perpendicular to the surface of the blade....
What is the role of water in photosynthesis? Which process requires more energy from the plant, moving water up through the xylem or moving nutrients down through the phylum to the roots or fruits? Explain. What is the function of palisade and spongy mesophyll?
Mesophyll tissue makes up the majority of the leaves of plants. Mesophyll tissue is made up of two types of cells: palisade parenchyma cells and spongy mesophyll cells. Palisade parenchyma cells contain many chloroplasts, while spongy mesophyll cells have more empty space, though they also contain...

For instance, the abscisic acid responsive element (ABRE, 9), the light response element (LRE, 12), the cis-acting regulatory element related to meristem expression (CAT-box, 3), and the cis-element involved in differentiation of the palisade mesophyll cells component (HD-Zip 1, 2). ...
The mesophyll is usually differentiated into columnar, or palisade, tissue, which consists of elongated cells with chloroplasts and occupies the upper part of the leaf that is turned toward the light. The spongy tissue is composed of cells with large intercellular spaces and fills the lower part ...
The largest uniquely expanded gene family (531-608 members) inP. pachyrhizicomprises sequences containing the Piwi (P-element Induced Wimpy testes in Drosophila) domain (Table2). Typically, the Piwi domain is found in the Argonaute (AGO) complex, where its function is to cleave ssRNA when gui...
Multiple sequence alignment of the sunflower NACs demonstrated that the N-terminus of all HaNACs have a conserved NAC domain, and five subdomains (Fig.S1). To better understand the relationship between the structure and function of these HaNAC proteins, the gene structure, and conserved motifs ...
