| Outline of Final Research Achievements |
Histology, anatomy and physiology in lear-miner attacked foliage. Leaf-miner is an endophagous insect infiltrating into live foliage and making a micro-cavity as a mine following feeding on mesophyll cells. <Anatomy> mine without leaf browning: no change of cell activity. mine with leaf browning: defensive reaction such as deposition of tannin, subprime and lignin as chemicals. Non browning leaf; no remarkable denaturation and necrosis of cells. decrease in Fv/Fm --> decrease in photosynthetic activity. remarkable decrease in Fm --> inhibition of oxygen transmission system PSII. Browning leaf; remarkable decrease in Fv/Fm --> palisade cells were fed. Decrease in Fo and Fm in mine part of leaf --> empty space of mine reduce light intensity reaching mesophyll cells. Mine is a separate space from outside and stable environment for leaf-miner. Gas concentration of air in mine might depend on a cuticle gas permeability.
