  • Only a small percentage of plant species undergo C(4) photosynthesis. Despite its rarity, the C(4) pathway has evolved numerous times from C(3) ancestors, with as many as 18 independent origins in grasses alone. We report non-Kranz (C(3)) anatomy in Aristida longifolia, a species in a genus of ca. 300 species previously thought to possess only Kranz (C(4)) anatomy. Leaf blade transections of A. longifolia show widely spaced vascular bundles, nonradiate chlorenchyma, and few or no chloroplasts… CONTINUE READING
