This study characterizes a nitric oxide synthase (NOS) from Ostreococcus tauri, a marine green alga. Like animal NOS sequences, O. tauri NOS contains an oxygenase and reductase domain. The… Expand
Assessment of the Genetic Diversity in Argentine Rice Cultivars with SSR Markers
Genetic diversity of rice (Oryza sativa L.) cultivars that are historically significance to rice breeding and production in Argentina were evaluated at the DNA level. Sixty-nine accessions were… Expand
Origin of sucrose metabolism in higher plants: when, how and why?
Since the discovery of sucrose biosynthesis, considerable advances have been made in understanding its regulation and crucial role in the functional biology of plants. However, important aspects of… Expand

Biosynthesis of sucrose-6-P catalyzed by sucrose-phosphate synthase (SPS), and the presence of sucrose-phosphate phosphatase (SPP) leading to the formation of sucrose, have both been ascertained in a… Expand
The Cinderella story of sucrose hydrolysis: Alkaline/neutral invertases, from cyanobacteria to unforeseen roles in plant cytosol and organelles
Over the past decades, considerable advances have been made in understanding the crucial role of sucrose and the regulation of its metabolism in plant life. Recent studies in cyanobacteria and the… Expand
Carbon Cycling in Anabaena sp. PCC 7120. Sucrose Synthesis in the Heterocysts and Possible Role in Nitrogen Fixation1[OA]
Nitrogen (N) available to plants mostly originates from N2 fixation carried out by prokaryotes. Certain cyanobacterial species contribute to this energetically expensive process related to carbon (C)… Expand
Sucrose metabolism: Anabaena sucrose‐phosphate synthase and sucrose‐phosphate phosphatase define minimal functional domains shuffled during evolution
Based on the functional characterization of sucrose biosynthesis related proteins [SBP: sucrose‐phosphate synthase (SPS), sucrose‐phosphate phosphatase (SPP), and sucrose synthase (SuS)] in Anabaena… Expand
Sucrose is involved in the diazotrophic metabolism of the heterocyst‐forming cyanobacterium Anabaena sp
Sucrose synthase (SuS) expression was studied in the filamentous, nitrogen‐fixing cyanobacterium Anabaena sp. PCC 7119. SuS activity, SusA polypeptide, and susA mRNA levels were lower in cells… Expand
New insights on sucrose metabolism: evidence for an active A/N-Inv in chloroplasts uncovers a novel component of the intracellular carbon trafficking
The presence of sucrose (Suc) in plastids was questioned for several decades. Although it was reported some decades ago, neither Suc transporters nor Suc metabolizing enzymes were demonstrated to be… Expand
Cyanobacterial alkaline/neutral invertases. Origin of sucrose hydrolysis in the plant cytosol?
The aim of this work was to investigate the occurrence of invertase (Inv) in cyanobacteria. We describe the first isolation and characterization of prokaryotic alkaline/neutral Inv (A/N-Inv) genes.… Expand
