Seed and 4-chloroindole-3-acetic acid regulation of gibberellin metabolism in pea pericarp.
In this study, we investigated seed and auxin regulation of gibberellin (GA) biosynthesis in pea (Pisum sativum L.) pericarp tissue in situ, specifically the conversion of [14C]GA19 to [14C]GA20. [14C]GA19 metabolism was monitored in pericarp with seeds, deseeded pericarp, and deseeded pericarp treated with 4-chloroindole-3-acetic acid (4-CI-IAA). Pericarp with seeds and deseeded pericarp treat...
متن کاملGlycosylated seryl residues in wall protein of elongating pea stems.
The protein content of salt-washed cell walls isolated from etiolated stems of Pisum sativum L. approximately doubled during elongation. In the same period the concentration in the wall of hydroxyproline, hydrazine-labile (= presumably glycosylated) serine, valine, tyrosine, lysine, and histidine increased markedly in comparison with other amino acids. After elongation was completed both the am...
متن کاملSoluble aldehyde dehydrogenase and metabolism of aldehydes by soybean bacteroids.
A soluble aldehyde dehydrogenase (EC 1.2.1.3) was partially purified from Rhizobium japonicum bacteroids and from free-living R. japonicum 61A76. The enzyme was activated by NAD+, NADH, and dithiothreitol, and it reduced NAD(P)+. Acetaldehyde, propionaldehyde, butyraldehyde, benzaldehyde, and succinic semialdehyde were substrates. The Km for straight-chain aldehydes decreased with increasing ca...
متن کاملCharacterization of an Endo-p-l,4-Glucanase Gene lnduced by Auxin in Elongating Pea Epicotyls'
A gene (EGLI) encoding an endo-p-l,4-~-glucanase (EGase, EC 3.2.1.4) of pea (Pisum sativum) has been cloned and characterized. EGL 1 encodes a 486-amino acid polypeptide, including a 24-mer putative signal peptide. The mature protein has a calculated molecular mas of 51.3 kD and an isoelectric point of 9.1. This pea ECase shares significant similarity with ECases from other plant species, but i...
متن کاملGlycine metabolism and oxalacetate transport by pea leaf mitochondria.
Isolated pea leaf mitochondria oxidatively decarboxylate added glycine. This decarboxylation could be linked to the respiratory chain (in which case it was coupled to three phosphorylations) or to mitochondrial malate dehydrogenase when oxalacetate was supplied. Decarboxylation rates measured as O(2) uptake, or CO(2) and NH(3) release were adequate to account for whole leaf photorespiration. Ox...
