ABA-REGULATION OF 2 CLASSES OF EMBRYO-SPECIFIC SEQUENCES IN MATURE WHEAT EMBRYOS

PLANT PHYSIOLOGY, 86(1), 208–215.

By: J. Williamson* & R. Quatrano

TL;DR: In vivo RNA labeling and the inhibitors alpha-amanitin and cycloheximide are used to determine the level at which ABA acts to modulate these sequences in cultured mature embryos, suggesting p1015 regulation might be at the level of selective RNA stability. (via Semantic Scholar)

1988 journal article

THE SYNTHESIS OF A 19-KILODALTON ZEIN PROTEIN IN TRANSGENIC PETUNIA PLANTS

PLANT PHYSIOLOGY, 88(4), 1002–1007.

By: J. Williamson*, G. Galili, B. Larkins * & S. Gelvin *

TL;DR: The results suggest that the 19 kilodalton zein gene, in addition to lacking specific sequences required for efficient transcription in dicots, might also lack sequences needed for the efficient synthesis, targeting, transport, or stabilization of the protein. (via Semantic Scholar)

1985 journal article

EM POLYPEPTIDE AND ITS MESSENGER-RNA LEVELS ARE MODULATED BY ABSCISIC-ACID DURING EMBRYOGENESIS IN WHEAT

EUROPEAN JOURNAL OF BIOCHEMISTRY, 152(2), 501–507.

By: J. Williamson*, R. Quatrano * & A. Cuming *

MeSH headings : Abscisic Acid / pharmacology; Cloning, Molecular; Cyclohexanecarboxylic Acids / pharmacology; DNA / analysis; Gene Expression Regulation / drug effects; Nucleic Acid Hybridization; Plant Growth Regulators; Plant Proteins / biosynthesis; Plant Proteins / genetics; Protein Biosynthesis; RNA, Messenger / metabolism; Triticum / embryology; Triticum / genetics; Triticum / metabolism
TL;DR: It is concluded that ABA specifically modulates Em message and protein levels in immature embryos, but is probably not responsible for the embryogenic specificity of Em expression. (via Semantic Scholar)
