New Phytol . 2021 Apr; 147(3):449-481. PMID: 33862930
Cyanobacteria are an ancient, morphologically diverse group of prokaryotes with an oxygenic photosynthesis. Many cyanobacteria also possess the ability to fix N . Although well suited to an independent existence...

Rai A, Rowell P, Stewart W
Planta . 2013 Dec; 151(3):256-64. PMID: 24301852
The lichen Peltigera aphthosa consists of a fungus and green alga (Coccomyxa) in the main thallus and of a Nostoc located in superficial packets, intermixed with fungus, called cephalodia. Dark...

Rai A, Rowell P, Stewart W
Planta . 2013 Dec; 152(6):544-52. PMID: 24301158
The Nostoc in the cephalodia of the lichen Peltigera aphthosa Willd. fixed (15)N2 and the bulk of the nitrogen fixed was continuously transferred from it to its eukaryotic partners (a...

Rai A, Lindblad P, Bergman B
Planta . 2013 Nov; 169(3):379-81. PMID: 24232650
Using the ammonium analogue (14)CH3NH 3 (+) , ammonium transport was studied in the cyanobiont cells freshly isolated from the root nodules of Cycas revoluta. An L-methionine-DL-sulphoximine (MSX)-insensitive ammonium-transport system,...

Torres A, Rai A, Hardiek M
Pediatrics . 2000 Mar; 105(3):E34. PMID: 10699136
Two children in the same household with symptomatic arterial hypertension simulating pheochromocytoma were found to be intoxicated with elemental mercury. The first child was a 4-year-old boy who presented with...

Singh A, Singh H, Rai A
Biochem Int . 1991 Dec; 25(5):887-94. PMID: 1687107
Methylammonium/ammonium ion, glutamine, glutamate, arginine and proline uptake, and their assimilation as nitrogen sources, was studied in Nostoc muscorum and its glutamine synthetase-deficient mutant. Glutamine served as nitrogen source independent...

Prakasham R, Rai A, Singh A, Singh H
Indian J Biochem Biophys . 1991 Aug; 28(4):263-6. PMID: 1684351
Effect of various types of nitrogen nutrition was studied on the uptake of ammonium, glutamate and glutamine by Nostoc muscorum and its Het-Nif- mutant. Ammonium nitrogen acted as a potent...

Rai A, Prakasham R
Indian J Biochem Biophys . 1989 Aug; 26(4):219-26. PMID: 2516834
NH4(+)-transport in Anabaena 7120 was studied using the NH4+ analogue, 14CH3NH3+. At pH 7, two energy-dependent NH4(+)-transport systems were detected in both N2- and NO3(-)-grown cells, but none in NH4(+)-grown...
