NITROGEN METABOLISM OF HALOPHYTES II. NITRATE AVAILABILITY AND UTILIZATION
TLDR
The results indicate there is an increase in nitrogen supply down the marsh, which may be associated with the input of nitrate during tidal innundation.
SOME UNUSUAL CHARACTERISTICS OF NITRATE REDUCTION IN ERYTHRINA SENEGALENSIS DC.
SUMMARY The characteristics of nitrate reduction exhibited by the tropical leguminous tree Erythrina senegalensis differ in several respects from those of other higher plants. Nitrate reduction in
Glutamine Synthetase Isoenzymes of Striga hermonthica and other Angiosperm Root Parasites
TLDR
The occurrence of multiple forms of glutamine synthetase in Striga hermonthica and other angiosperm root parasites was investigated and the kinetic and physical properties of GS, and GS2 of theseAngiosperm parasites were similar to those of the isoenzymes in other non-parasitic angiosperms.
NITROGEN METABOLISM OF HALOPHYTES.
Summary Ion-exchange chromatography on DEAE-Sephacel revealed the presence of two forms of glutamine synthestase (GSI and GSII) in leaf tissue and one form in root tissue of the angiosperm
Ammonium repression of nitrate reductase formation in Lemna minor L.
TLDR
It is suggested that both the nitrate stimulation and the ‘ammonium’ inhibition of nitrate reductase formation can be accounted for by a transcriptional control system.
Ammonium inactivation of nitrate reductase in Lemna minor L.
TLDR
The addition of ammonium to nitrate induced plants of Lemna minor L. brings about a rapid loss in extractable nitrate reductase activity, which is reversible both in vivo and in vitro.
Birth Asphyxia, Perinatal and Maternal Mortality Associated With Caesarean Section
TLDR
The hazards of caesarean section are worse with emergency surgery but significant asphyxia occurs even following elective section, and early appropriate referral of high-risk cases will help to reduce perinatal/maternal morbidity and mortality.
