13 C-Metabolic flux analysis (13 C-MFA) has greatly contributed to our understanding of plant metabolic regulation. However, the generation of detailed in vivo flux maps remains a major challenge. Flux investigations based on nuclear magnetic resonan

Recent results suggest that metabolism-mediated stomatal closure mechanisms are important to regulate differentially the stomatal speediness between ferns and angiosperms. However, evidence directly linking mesophyll metabolism and the slower stomata

PEPc-mediated CO2 assimilation provides carbons to gluconeogenesis and the TCA cycle in both dark-exposed and illuminated guard cells

Autor: Valéria F. Lima, Alexander Erban, David B. Medeiros, Joachim Kopka, Danilo M. Daloso, Francisco Bruno S. Freire, Alisdair R. Fernie, Markus Schwarzländer, Nicole P. Porto, Silvio A. Cândido-Sobrinho

Evidence suggests that guard cells have higher rate of phosphoenolpyruvate carboxylase (PEPc)-mediated dark CO2 assimilation than mesophyll cells. However, it is unknown which metabolic pathways are activated following dark CO2 assimilation in guard

Summary13C-Metabolic flux analysis (13C-MFA) have greatly contributed to revealing the regulation of plant metabolism. However, mass spectrometry (MS) approaches have hitherto been limited in their power to deduce flux information due to lack of posi

Stomatal responses to environmental signals differ substantially between ferns and angiosperms. However, the mechanisms that lead to such different responses remain unclear. Here we investigated the extent to which leaf metabolism contributes to coor

Publikováno v: Plant signalingbehavior. 13(8)

Plant atmospheric CO(2) fixation depends on the aperture of stomatal pores at the leaf epidermis. Stomatal aperture or closure is regulated by changes in the metabolism of the two surrounding guard cells, which respond directly to environmental and i
