Photosynthetic Characteristics of C3-C4 Intermediate Flaveria
Four species of the genus Flaveria, namely F. anomala, F. liaris, F. pubescens, and F. ramosissima, were identified as intermediate C3-C4 plants based on leaf anatomy, photosynthetic CO2 compensation point, 02 inhibition of photosynthesis, and activities of C4 enzymes. F. anomala and F. rawosissina exhibit a distinct Kranz-like leaf anatomy, similar to that of the C4 species F. trinervia while ...
متن کاملGrowth of the C4 dicot Flaveria bidentis: photosynthetic acclimation to low light through shifts in leaf anatomy and biochemistry
In C(4) plants, acclimation to growth at low irradiance by means of anatomical and biochemical changes to leaf tissue is considered to be limited by the need for a close interaction and coordination between bundle sheath and mesophyll cells. Here differences in relative growth rate (RGR), gas exchange, carbon isotope discrimination, photosynthetic enzyme activity, and leaf anatomy in the C(4) d...
متن کاملThe gene for the P-subunit of glycine decarboxylase from the C4 species Flaveria trinervia: analysis of transcriptional control in transgenic Flaveria bidentis (C4) and Arabidopsis (C3).
Glycine decarboxylase (GDC) plays an important role in the photorespiratory metabolism of plants. GDC is composed of four subunits (P, H, L, and T) with the P-subunit (GLDP) serving as the actual decarboxylating unit. In C(3) plants, GDC can be found in all photosynthetic cells, whereas in leaves of C(3)-C(4) intermediate and C(4) species its occurrence is restricted to bundle-sheath cells. The...
متن کاملInitial events during the evolution of C4 photosynthesis in C3 species of Flaveria.
The evolution of C4 photosynthesis in many taxa involves the establishment of a two-celled photorespiratory CO2 pump, termed C2 photosynthesis. How C3 species evolved C2 metabolism is critical to understanding the initial phases of C4 plant evolution. To evaluate early events in C4 evolution, we compared leaf anatomy, ultrastructure, and gas-exchange responses of closely related C3 and C2 speci...
