Total aminoacylation of glycine and leucine transfer RNAs was compared between chilled and nonchilled hypocotyls of 7-day-old soybean seedlings. Total charging was greater for both specific transfer RNAs from nonchilled sources. Isoaccepting transfer RNA species for glycine and leucine were fractionated using reverse phase column chromatography. Leucyltransfer RNAs were fractionated into six distinct fractions with relatively small shifts appearing in specific fractions between chilled and nonchilled sources. Glycyl-transfer RNAs were fractionated into two distinct fractions with major shifts appearing for both fractions between chilled and nonchilled sources.
