Abstract excerpt
We report that wall ingrowth deposition in phloem parenchyma (PP) transfer cells (TCs) in leaf veins of Arabidopsis (Arabidopsis thaliana) represents a novel trait of heteroblasty. Development of PP TCs involves extensive deposition of wall ingrowths adjacent to cells of the sieve element/companion cell complex. These PP TCs potentially facilitate phloem loading by enhancing efflux of symplasmic Suc for...
