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
Transport (SAP) Transport (SAP) A SAP transport is a package which is used to transfer data from one SAP installation to another. This data can range from a simple printer driver to a whole SAP client. It can be considered as an "update", with the only difference being that SAP transports are made by the SAP users themselves. Transports can also be used to transfer data from external applications. Most of the time the SAP transports are used to implement some new features in a production system. Since a production system (especially a business-dependent one) cannot be used for development (and testing),
