Variation of mesophyll conductance mediated by nitrogen form is related to changes in cell wall property and chloroplast number.

ABSTRACT: Plants primarily incorporate nitrate (NO₃ ^-) and ammonium (NH₄ ⁺) as the primary source of inorganic nitrogen (N); the physiological mechanisms of photosynthesis (A) dropdown under NH₄ ⁺ nutrition has been investigated in many studies. Leaf anatomy is a major determinant to mesophyll conductance (g _m) and photosynthesis; however, it remains unclear whether the photosynthesis variations of plants exposed to different N forms is related to leaf anatomical variation. In this work, a common shrub, Lonicera japonica was hydroponically grown under NH₄ ⁺, NO₃ ^- and 50% NH₄ ⁺/NO₃ ^-. We found that leaf N significant
