Sap transport proteins. Recent evidence indicates that mobile proteins and RNA are part of the plant's long-distance communication signaling system. Evidence also exists for the directed transport and sorting of macromolecules as they pass through plasmodesmata." A large number of insects of the order Hemiptera (the half-wings), feed directly on phloem sap, and make it the primary component of their diet. Phloem sap is "nutrient-rich compared with many other plant products and generally lacking in toxins and feeding deterrents, [yet] it is consumed as the dominant or sole diet by a very restricted range of animals". This apparent paradox is explained
Japanese tissue be reinserted by being sewn first onto a strip of Japanese paper, and then by pasting into the book along the newly formed hinge between the Japanese paper and original signature. Japanese tissue Japanese tissue is a thin, strong paper made from vegetable fibers. Japanese tissue may be made from one of three plants, the "kōzo" plant ("Broussonetia papyrifera", paper mulberry tree), the mitsumata ("Edgeworthia chrysantha") shrub and the gampi tree ("Diplomorpha sikokiana"). The long, strong fibers of the kōzo plant produce very strong, dimensionally stable papers, and are the most commonly used fibers in the making of Japanese paper
