From: Anatomically induced changes in rice leaf mesophyll conductance explain the variation in photosynthetic nitrogen use efficiency under contrasting nitrogen supply

Fig. 1

The relationship between leaf N content (NL) and the photosynthetic rate (Pn) (a) and photosynthetic nitrogen use efficiency (PNUE) (b) and the relationship between PNUE and the ratio of chloroplast CO2 concentration to Rubisco (Cc/Rubisco) (c) and the ratio of mesophyll conductance to Rubisco (gm/Rubisco) (d). Each point represents one replicate (four replicates per treatment). The lines represent the following regression equations: a y = − 1.8756 × 2 + 11.3310x + 13.0290, R2 = 0.6228, P < 0.05; b y = − 0.0763x + 0.3565, R2 = 0.7886, P < 0.05; c y = 0.0017x + 0.0774, R2 = 0.8295, P < 0.01; d y = 1.5663x + 0.0733, R2 = 0.4215, P < 0.01
