Absorbance spectrum of non-irradiated (control) egg extracts at pH8 (dotted line) and pH3 (solid line).
<p>Wavelengths cover almost the entire UV spectrum (UVC: 200â280 nm, UVB: 280â315 nm, and UVA: 315â400 nm). Absorption is shown as arbitrary units.</p
Representative examples of flow-cytometry histograms obtained from nuclear suspensions (5â10,000 counts) of Propidium Iodide (PI) stained larval samples.
<p>a) Control diploid (2n) larva (CV: 5%); b) haploid (n) larva produced with a UV-dose of 60 mJ.cm<sup>â2</sup> (CV: 10%). DNA values on the X-axis are reported in arbitrary units expressed as fluorescent channel numbers (PE-A). G2 represent mitotic peaks.</p
Morphology of control and UV-treated embryos and larvae.
<p>a) Control embryo at 74 h pf; b) control larva at hatching; c) UV treated embryos at 74 hpf showing microcephaly, short and large body; d) UV-treated larvae at hatching showing microphtalmy, short body and curved tail. Scale bars represent 500 ”m.</p
Percent survival relative to controls of treated groups exposed to different cumulative UV-doses in the range 7.2â720 mJ.cm<sup>â2</sup>.
<p>Error bars represent standard deviations of means (STD).</p
Percent survival relative to controls of hatched larvae issued from the different UV-irradiation treatments (7.2â72 mJ.cm<sup>â2</sup>.min<sup>â1</sup>) lasting 0.5â12 min.
<p>Error bars represent standard deviations of means (STD).</p
Microsatellite marker loci transmission in three putative androgenetic progenies (A1, B1 and C2) produced with a UV-dose of 60 mJ.cm<sup>â2</sup>.
<p>Genotypes of progenies showing only discriminant paternal alleles are presented in bold characters. For putative androgenetic progenies, homozygous or haploid alleles are only written once since genotyping cannot distinguish between the presence of one or two copies of the same allele. N represents the number of analyzed individuals in each progeny.</p><p>Microsatellite marker loci transmission in three putative androgenetic progenies (A1, B1 and C2) produced with a UV-dose of 60 mJ.cm<sup>â2</sup>.</p
