Phloem Loading and Associated Processes

Abstract

Phloem loading is the process by which the major translocate species are selectively and actively taken up by the sieve tubes, especially in the minor veins of source regions. The entry of other solutes which may readily but passively move into the phloem is not considered to be part of phloem loading. One of the earliest and possibly the first mention of the phloem loading concept in the literature was in the work by Barrier and Loomis (1).
