Translocation and Assimilates Partitioning in Higher Plants

The following points highlight the four factors controlling translocation and assimilates partitioning in higher plants. The factors are: 1. Competition among Sink Tissues for Available Translocated Assimilates 2. Photosynthesis and Sink Demand 3. Long Distance Signals between Sources & Sinks and 4. Plasmodesmata. Factor # 1. Competition among Sink Tissues for Available Translocated Assimilates: Competition among various sink tissues or [...]

Phloem Loading and Unloading in Plants

The below mentioned article provides an useful note on the phloem loading and unloading in plants. Translocation of organic solutes such as sucrose (i.e., photosynthetic) takes place through sieve tube elements of phloem from supply end (or source) to consumption end (or sink). But, before this translocation of sugars could proceed, the soluble sugars must be transferred from mesophyll cells [...]
