16228377-4	2003	Acclimation of photosynthesis to high CO(2) occurs in both C(3) and C(4) plants, most notably in nutrient-limited situations.	co(2)	38-43	complement C3	Homo sapiens	59-63	
16228377-3	2003	Rising CO(2) generally stimulates C(3) photosynthesis more than C(4), but C(4) species still exhibit positive responses, particularly at elevated temperature and arid conditions where they are currently common.	co(2)	7-12	complement C3	Homo sapiens	34-38	
16661586-1	1980	A survey of the K(m)(CO(2)) values of ribulose-1,5-bisphosphate carboxylase from 60 grass species shows that enzyme from C(3) grasses consistently exhibits lower K(m)(CO(2)) than does that from C(4) grasses.	co(2)	21-26	complement C3	Homo sapiens	121-125	
12031901-7	2002	The detection of glyoxylic acid and CO(2)(-*) from Asp demonstrates the occurrence of competing beta-scission processes for the Asp C-3 alkoxyl radical.	co(2)	36-41	complement C3	Homo sapiens	132-135	
22128120-1	2011	In the late 1960s, a vibrant new research field was ignited by the discovery that instead of fixing CO(2) into a C(3) compound, some plants initially fix CO(2) into a four-carbon (C(4)) compound.	co(2)	100-105	complement C3	Homo sapiens	113-117	
21632342-5	2008	Thermotolerance of P(n) in elevated (vs. ambient) CO(2) increased in C(3), but decreased in C(4) (especially) and CAM (high growth temperature only), species.	co(2)	50-55	complement C3	Homo sapiens	69-73
