CspA and CspB transgenic maize plants demonstrate improved end-of-season grain yield under water-limiting conditions

Mean yield values (tons/hectare) of nontransgenic and transgene-positive plots are shown for groupings of CspA and CspB events and for two individual transgenic events from each construct. Experimental details are described in Supplemental Materials and Methods S1.

Event-Event Pool	Yield	Yield Improvement
	t/ha
CspA nontransgenic mean	6.38
CspA-event group mean	6.68	4.6% (P < 0.2)
CspA-Zm event 1	8.35	30.8% (P < 0.1)
CspA-Zm event 2	7.52	18.3% (P < 0.1)
CspB nontransgenic mean	6.86
CspB-event group mean	7.38	7.5% (P < 0.1)
CspB-Zm event 1	8.26	20.4% (P < 0.1)
CspB-Zm event 2	7.61	10.9% (P < 0.1)
