Because trichome phenotypes on the first two leaves are indistinguishable, data were pooled. Consequently, n for leaf 1,2 is twice the n given for the number of plants. Branch phenotype refers to the numbers of processes on the trichome. The number 1 refers to an unbranched spike. The number 2 is a two-branched trichome, etc. 1/14/99—3A, 6A, 6B, 4A, and 12/21/98—8A are gl3-1 transformed with the GL3 genomic clone, pD2LX. 4/15/98—17A, 17B, and 17F are WS wild type transformed with the GL3 antisense clone, pEZF1. n, number of individual plants counted for each strain.
