Leaf tissue was sampled from 8-month-old plants of three representative lines. Values represent means from three biological samples ± standard errors. Means are compared column-wise. Values with different letters are significantly different (p < 0.0001). BvLzm: maize codon-optimized bovine lysozyme (BvLz); pUPE:BvLzm: BvLzm expressed from three promoters, maize ubiquitin 1, sugarcane proline-rich protein and sugarcane elongation factor 1α (pSHEF1α); pUDE:BvLzm: BvLzm expressed from three promoters, maize ubiquitin 1, sugarcane dirigent16 and pSHEF1α; HF: high fertilization rate; LF: low fertilization rate.
