FIGURE 3. Colour patterns of some of the variation recognised in taxa now included in H. viridiflavus. After Laurent (1983): 1–9, 11–13 Hyperolius karissimbiensis françoisi; 10, 14, 16–18 Hyperolius viridiflavus xanthogrammus; 15, 19–26 Hyperolius viridiflavus hybridus. After Ahl (1931): 27–31 Hyperolius variabilis. Ahl's illustrations were taken from Tornier (1897).
Genotyping-by-sequencing-based identification of Arabidopsis pattern recognition receptor RLP32 recognizing proteobacterial translation initiation factor IF1
<p>Activation of plant pattern-triggered immunity (PTI) relies on the recognition of microbe-derived structures, termed patterns, through plant-encoded surface-resident pattern recognition receptors (PRRs). We show that proteobacterial translation initiation factor 1 (IF1) triggers PTI in <em>Arabidopsis thaliana</em> and related Brassicaceae species. Unlike for most other immunogenic patterns, IF1 elicitor activity cannot be assigned to a small peptide epitope, suggesting that tertiary fold features are required for IF1 receptor activation. We have deployed natural variation in IF1 sensitivity to identify <em>Arabidopsis</em> leucine-rich repeat (LRR) receptor-like protein 32 (RLP32) as IF1 receptor using a restriction site-associated DNA sequencing approach. RLP32 confers IF1 sensitivity to rlp32 mutants, IF1-insensitive <em>Arabidopsis</em> accessions and IF1-insensitive <em>Nicotiana benthamiana</em>, binds IF1 specifically and forms complexes with LRR receptor kinases SOBIR1 and BAK1 to mediate signaling. Similar to other PRRs, RLP32 confers resistance to <em>Pseudomonas syringae</em>, highlighting an unexpectedly complex array of bacterial pattern sensors within a single plant species.</p>
FIGURE 3b. Maximum likelihood phylogram constructed from combined cyt b and 12S rRNA sequences for 20 in Specific limits and emerging diversity patterns in East African populations of laminate-toothed rats, genus Otomys (Muridae: Murinae: Otomyini): Revision of the Otomys typus complex 3024
FIGURE 3b. Maximum likelihood phylogram constructed from combined cyt b and 12S rRNA sequences for 20 Otomys specimens, one representative of Parotomys brantsii and four murine outgroups under the best-fit GTR+I+G model. Support indices for each node (1 – 23) are given beside the phylogram (BPP/ MLbs/ UwPbs/ 6PPbs/ NJpbs/ Njcbs). For both phylogenies (Figure 3a and 3b), the relative branch thickness indicates significant nodal support from the phylogenetic reconstruction methods employed herein (four to six methods—thick lines; two methods—intermediate lines). Dashed lines show unsupported relationships; Abbreviations and symbols: NS - BPP <0.95; "-" indicates that the node was not present in the relevant analysis, or percentage bootstrap support below 50%.
Multiple sequence alignments and phylogenetic trees from: Co-option of the limb patterning program in cephalopod eye development
<p>Background</p> <p><span>Across the Metazoa, similar genetic programs are found in the development of analogous, independently evolved, morphological features. The functional significance of this reuse and the underlying mechanisms of co-option remain unclear. Cephalopods have evolved a highly acute visual system with a cup shaped retina and a novel refractive lens in the anterior, important for a number of sophisticated behaviors including predation, mating and camouflage. Almost nothing is known about the molecular-genetics of lens development in the cephalopod.</span></p> <p><span>Results</span></p> <p><span>Here we identify the co-option of the canonical bilaterian limb pattering program during cephalopod lens development, a functionally unrelated structure. We show radial expression of transcription factors <i>SP6-9/sp1, Dlx/dll, </i><i>Pbx/exd, Meis/hth, </i>and a <i>Prdl</i> homolog in the squid <i>Doryteuthis pealeii</i>, similar to expression required in <i>Drosophila</i> limb development.<i> </i>We assess the role of Wnt signaling in the cephalopod lens, a positive regulator in the developing <i>Drosophila </i>limb, and find the regulatory relationship reversed, with ectopic Wnt signaling leading to lens loss. </span></p> <p><span>Conclusion</span></p> <p><span>This regulatory divergence suggests that duplication of SP6-9 in cephalopods may mediate the co-option of the limb patterning program. Thus our study suggests that the limb network could perform a more universal developmental function in radial pattering and highlights how canonical genetic programs are repurposed in novel structures.</span></p>
