The preparation of 2,3(3H)-Ga29 and its metabolism by etiolated seedlings and germinating seeds of dwarf Pisum sativum (Meteor.)
Description
The (3H)-GA29 was prepared biosynthetically from (3H)-GA20 by germinating pea seeds. (3H)-GA29 applied to dark-grown seedlings and germinating seeds of dwarf Pisum was converted into polar, acidic products, but analysis of these products by mass spectrometry was rendered impossible by low levels of metabolites, and a lack of unlabelled GA29 with which to increase metabolite pool-sizes. The results are discussed in relation to recent attempts to investigate the pathways of gibberellin biosynthesis in higher plants, and to draw attention to some of the problems associated with these investigations
Abstract (Afrikaans)
Die (3H)-GA29 is biosinteties van (3H)-GA20 voorberei deur ertjiesade te ontkiem. (3H)-GA29 toegedien aan in die donker gekweekte saailinge en ontkiemende sade van dwerg Pisum is verander tot polare suurvormendeprodukte maar ontleding van die produkte deur massa spektrometrie was onmoontlik weens die lae vlakte van metaboliet en die afwesigheid van ongemerkte GA29 om die metabolietpoel te vergroot. Die resultate word bespreek in die lig van die jongste pogings om die gibberellin biosintese roete in hoer plante na te speur en om die aandag op sekere probleme verbonde aan hierdie navorsing, te verligAdditional details
