Physiological profiles associated with ceasing growth of unfertilized eggs produced by unmated queens in the subterranean termite Reticulitermes chinensis.

Li G, Liu L, Sun P, Wu Y, Lei C, Chen X, Huang Q - Biol Open (2016)

Bottom Line: In Reticulitermes chinensis, a close relative of R. speratus with asexual queen succession, unfertilized eggs can be produced but do not hatch as larvae.Fertilized eggs had significantly lower quantities of five amino acids (Cys, Met, Ile, Leu and Tyr), Ca, protein and cholesterol during development.Overall, changes in these physiological indices may substantially affect ovarian and embryonic growth and inhibit development of unfertilized eggs in R. chinensis.

BIO017319F3: Differences in the levels of 11 amino acids between unfertilized eggs/unmated queens and fertilized eggs/mated queens. Data represented as mean±s.e.m. Asterisks denote significant differences by paired t-test; n=4; *P<0.05; **P<0.01; ***P<0.001.

Mentions: The levels of five amino acids (Cys, Met, Ile, Leu and Tyr) in unfertilized eggs from FF colonies were significantly higher than in fertilized eggs from FM colonies (Fig. 3A; Table S1; Cys: t=−8.000, d.f.=2, P=0.015; Met: t=−6.424, d.f.=2, P=0.023; Ile: t=−10.250, d.f.=2, P=0.009; Leu: t=−5.277, d.f.=2, P=0.034; Tyr: t=−9.430, d.f.=2, P=0.011). The levels of two amino acids (Asp and Ala) in unmated queens were significantly lower than in mated queens (Fig. 3B; Asp: t=4.014, d.f.=2, P=0.016; Ala: t=10.123, d.f.=2, P=0.001), but the levels of six amino acids (Gly, Ile, Leu, Phe, His and Arg) in unmated queens were significantly higher than in mated queens (Fig. 3B; Gly: t=−5.354, d.f.=2, P=0.006; Ile: t=−15.296, d.f.=2, P<0.001; Leu: t=−3.101, d.f.=2, P=0.036; Phe: t=−4.177, d.f.=2, P=0.014; His: t=−5.494, d.f.=2, P=0.005; Arg: t=−5.087, d.f.=2, P=0.007).Fig. 3.
