Volume rendered projection of serial block face scanning electron micrographs of sieve plates in root protophloem of 4-day-old seedlings. The sieve plate between the first fully enucleated SE is defined as sieve plate 1. Note individual atypically small sieve pores (asterisks) and occasional clustering (arrows) in pll12 PSE sieve plates. Scale bars, 2 μm. Images are subset of Figure S6A.
