the effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
Genotypically Identifying Wheat Mesophyll Conductance Regulation under Progressive Drought Stress
Photosynthesis limitation by CO2 flow constraints from sub-stomatal cavities to carboxylation sites in chloroplasts under drought stress conditions is, at least in some plant species or crops not fully understood, yet. Leaf mesophyll conductance for CO2 (gm) may considerably affect both photosynthesis and water use efficiency (WUE) in plants under drought conditions. The aim of our study was to...
متن کاملRole of mesophyll diffusion conductance in constraining potential photosynthetic productivity in the field.
Limited mesophyll diffusion conductance to CO(2) (g(m)) can significantly constrain plant photosynthesis, but the extent of g(m)-limitation is still imperfectly known. As g(m) scales positively with foliage photosynthetic capacity (A), the CO(2) drawdown from substomatal cavities (C(i)) to chloroplasts (C(C), C(i)-C(C)=A/g(m)) rather than g(m) alone characterizes the mesophyll diffusion limitat...
متن کاملImportance of mesophyll diffusion conductance in estimation of plant photosynthesis in the field.
Mesophyll diffusion conductance to CO(2) (g(m)) is an important leaf characteristic determining the drawdown of CO(2) from substomatal cavities (C(i)) to chloroplasts (C(C)). Finite g(m) results in modifications in the shape of the net assimilation (A) versus C(i) response curves, with the final outcome of reduced maximal carboxylase activity of Rubisco (V(cmax)), and a greater ratio of the cap...
