Miller-et-al-2021: Datasets to accompany AJB manuscript submission

Phloem tissue allows for sugar transport along the entirety of a plant, and thus is one of the most important anatomical structures related to growth. It is thought that the sugar conducting sieve tube may overwinter and its cells persist multiple seasons in deciduous trees. One possible overwinter strategy is to build up callose on phloem sieve plates to temporarily cease function. These three datasets were collected to explore seasonal callose deposition, seasonal xylem conductivity, and sieve plate pore size in five deciduous tree species, and used to test the hypothesis that tree species produce callose on their sieve plates on a seasonal basis, mimicking overwintering patterns found in xylem.
