A tomato phloem-mobile protein regulates the shoot-to-root ratio by mediating the auxin response in distant organs.


The plant vascular system serves as a conduit for delivery of both nutrients and signaling molecules to various distantly located organs. The anucleate sieve tube system of the angiosperm phloem delivers sugars and amino acids to developing organs, and has recently been shown to contain a unique population of RNA and proteins. Grafting studies have… (More)
