In vivo Phosphorylation of Phosphoenolpyruvate Carboxylase in Egeria densa, a Submersed Aquatic Species [PDF]

open access: yesPlant and Cell Physiology, 2001
In vivo phosphorylation of PEPC in Egeria densa was studied using plants at high temperature and in light, and plants kept at low temperature and in light. The isoform induced by high temperature and light was more phosphorylated in the light. Changes in kinetic and regulatory properties correlated with changes in the phosphorylation state of PEPC.

Genetic diversity in Egeria densa and E. najas in Jupiá Reservoir, Brazil [PDF]

open access: yesCiencia e investigación agraria, 2012
The aquatic plant species Egeria densa (Planch.) Casp and E. najas Planchon occur naturally in the Parana River Basin of  southeastern Brazil. Hydroelectric dam construction in the river basin has created several lakes, changing the ecology of the river and altering the population ecology of Egeria .

Glitter Interference On Photosynthetic Rates of A Submerged Macrophyte (Egeria Densa) [PDF]

open access: yes, 2021
Abstract This study analyzed the photosynthetic rates (by the light and dark bottle method) of the submerged macrophyte Egeria densa in the presence of three concentrations of glitter: 0.0235 g (T1/T4), 0.0117 g (T2/T5) and 0.0058 g (T3/T6), as well in its absence (control treatment, CT1 and CT2). About 800 apical fragments of E.
