Species within subfamilies and tribes of the Gramineae that have low carbon dioxide compensation values are either short-day or day-neutral in their photoperiodic requirement for flowering; those with high carbon dioxide compensation values are long-day, with a few exceptions. Photoperiodic screening of some species of Atriplex, Amaranthus, and Panicum revealed that the species with the C4 syndrome are quantitative short-day or day-neutral, except for P. miliaceum. Those lacking the C4 syndrome have a qualitative short-day requirement for flowering. It is assumed that the C4 syndrome is a derived condition from C3 plants with CAM (crassulacean acid metabolism) plants probably in between. The photoperiodic responses of the plants seem to have a coevolutionary trend with photosynthetic characters, from long-day types to short-day ones, with plants having a dual photoperiodic requirement in between.
