mRNA expression levels were quantitated fluorometrically after size verification on agarose gels (see Methods) and are expressed as mean percentages ± sd of measured β-tubulin mRNA levels. High sd of primary leaf mRNA is the result of the difficulty in excising small (approximately 7% of total seedling fresh weight) primary leaves at this stage of development.
