Figure 7From: Nitrogen limitation and high density responses in rice suggest a role for ethylene under high density stressExpression of three senescence associated genes in plants grown under high (HD) and low (LD) density conditions at both 21 and 31 day time points. All data is mean ± 1 standard error. For statistical significance (*) t-test was applied for every pair of means for a given gene at a given time point (p < 0.05, n = 3).Back to article page
