Fig. 3From: Investigation of three enzymes and their roles in the embryonic development of parthenogenetic Haemaphysalis longicornisDynamic changes of cathepsin D during embryonic development of parthenogenetic H. longicornis. a Gene transcripts of cathepsin D. b Activity of cathepsin D. The levels of gene mRNA expression were normalised against the mRNA of β-actin and the error bars represent the mean ± SE values and the letters (a, b, c, d) labels represent significant differences (P ≤ 0.0001)Back to article page
