Development of in vitro lily scale budlets as related to virus elimination

Creator:

Ruttum, Joanne C.

Abstract:

Lily hybrids vary in their ability to produce virus-free (VF) bulblets when grown from virus-infected scales in tissue culture. Asiatic hybrids typically produce a higher percentage of in vitro VF scale bulblets than do Lilium longiflorum cultivars. Three hypotheses concerning the cause of this variation are tested on five lily...

The terminal reactions in the biosynthesis of methionine in Saccharomyces cerevisiae

Creator:

Pigg, C. JoAnne

Abstract:

The terminal reactions in the biosynthetic pathway of methionine in Saccharomyces cerevisiae were investigated in this study. Analyses of a number of methionine auxotrophs for biochemical deficiences established four mutant groups. It was observed from qualitative feeding experiments that some auxotrophs were able to utilize S-adenosylmethionine (AM) and S-adenosyl-homocysteine (AH)...
