A blueprint for C4 photosynthesis in the rice paddy: insights from the noxious weed Echinochloa glabrescens

ABSTRACT: The C4 pathway is a highly complex trait that increases photosynthetic efficiency in over sixty plant lineages. Although the majority of C4 plants occupy disturbed, arid and nutrient-poor habitats, some grow in high-nutrient, waterlogged conditions. One such example is Echinochloa glabrescens, which is an aggressive weed of rice paddies. We generated comprehensive transcriptome datasets for C4 E. glabrescens and C3 rice to identify genes associated with adaption to waterlogged, nutrient-replete conditions, but also used the data to better understand how C4 photosynthesis operates in these conditions. Similar to arid C4 species, leaves of E. glabrescens exhibited classical Kranz anatomy with lightly lobed mesophyll cells. As with rice and other hygrophytic C3 species, leaves of E. glabresce
