Of 24 amino acids tested all except glutamic and aspartic acids were able to block completely the transcription of mRNA for zoosporangium production of A. macrogynus within 30 min and for a period of at least 5 h at concentrations which were not excessively toxic. After 5 h terminal resistant sporangia developed with seven of the amino acids and zoosporangia with the others. The uptake, utilization and toxicity of amino acids were explored to explain the differences observed. Conditions for the controlled production of resistant sporangia were optimized for the glucose-leucine combination. Some amino acids were also able to inhibit zoosporangium development after mRNA transcription and before deposition of the septum. In the development of resistant sporangia stable mRNA was involved at least until the wall was acid-resistant. Synthesis of new mRNA was required to convert a developing resistant sporangium to a zoosporangium when the supply of glucose was inadequate.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
