Sampling and Analysis of Phloem Sap

摘要: The transport tubes of the phloem are essential for higher plants. They not only provide route distribution assimilates produced during photosynthesis from source to sink organs but also (re-) distribute mineral nutrients. Additionally, is sending information between distant plant and steering developmental defense processes. For example, flowering tuberization time controlled by phloem-mobile signals important reactions on whole level, like systemic acquired resistance or gene silencing, spread through phloem. In addition, recent results demonstrate that allocation nutrients coordinated mobile signaling molecules. However, in many studies analysis sap neglected, probably because content sieve easy access. This chapter will describe current methods sampling order encourage researchers include this crucial compartment their relevant studies.
