Ear and kernel development

(a) Non-transformed (left) and hemizygous (right) ears from plants of the same age before pollination. b) Weight of kernels from non-transformed ears pollinated with pollen from non-transformed (NT) or hemizygous (P+) plants. (c) Weight of kernels from non-transformed ears pollinated with pollen from hemizygous transformants. Kernels were taken from the same ear and classified as P–×P– or P–×P+ by PCR with 1-specific primers. Values for (b) are means (±SE) of all kernels of four ears. Values for (c) are means (±SD) of 15±2 kernels.Copyright information:Taken from "Over-expression of a zeatin -glucosylation gene in maize leads to growth retardation and tasselseed formation"Journal of Experimental Botany 2008;59(10):2673-2686.Published online 31 May 2008PMCID:PMC2486472.
