Partial purification and determination of some properties of an aminotransferase of pea (Pisum sativum L.) plants

Creator:: Matheron, Michael Earl
Abstract:: A transaminase (aminotransferase, EC 2. 6. 1) was extracted and purified approximately 148-fold from shoot tips of pea (Pisum sativum L. cv. Alaska) seedlings and some properties of the enzyme were determined. The purification included acetone precipitation followed by column chromatography on hydroxylapatite. With a-ketoglutarate as co-substrate, the acetone precipitated...

Annual bluegrass (Poa annua L.) control with ethofumesate during turfgrass establishment

Creator:: Wieneche, David L.
Abstract:: Temperate climates are particularly conducive to growth of annual bluegrass which readily invades and dominates most cool-season turfgrasses. Ethofumesate (2-ethoxy-2,3-dihydro-3,3-dimethyl-5-benzofuranyl methanesulfonate) is one herbicide available which will selectively control annual bluegrass. The primary objectives of this research were to determine optimum application rates and timing of ethofumesate for control of...
