2 自我简介 2
3 Course / workshop Workshop on Molecular Evolution (Since 1988) Workshop on Phylogenomics (Since 2017) 3
4 4 Phylogenetics
5 Utilities of phylogenetic tree Relationship Species delimitation Divergence time and Biogeography Evolutionary process (selections, ancestral state) 5
6 6 Molecular Phylogenetics
7 No. of genes Histories of data sampling High Phylogenomics Low 7
8 Why we need many genes? Gene A Gene B 8 Rokas & Chatzimanolis (2008) in Phylogenomics (W. J. Murphy, Ed.)
9 Histories of data sampling 9 (Slide from Casey Dunn)
10 Phylogenomics Phylogenomics: inference of species phylogeny with lots of genes Whole genome Whole transcriptome Targeted enrichment Directed PCR 10 (Slide from Casey Dunn)
11 Phylogenomics 11 Delsuc et al. 2005
12 Phylogenomic power 12 (Slide from Antonis Rokas)
13 13 But Incongruences still exist in phylogenomic studies
14 Incongruence: avian Kimball et al, MPE 2013
15 Incongruence: squamates Mitochondrial genome Castoe et al. PNAS 2009
16 Incongruence: Ascoideaceae ( 酱霉科 ) ML BS=82 ML BS=100 1,559-gene and 38-taxon Riley et al. PNAS ,233-gene and 86 yeasts Shen et al. G3 2016
17 How could we quantify phylogenetic signal for each gene?
18 Maximum Likelihood ( 最大似然法 ) Substitution model 18
19 Maximum Likelihood ( 最大似然法 ) Sp1 Sp3 Sp1 Sp2 Sp1 Sp2 Sp2 Sp4 Sp3 Sp4 Sp4 lnl= lnl= lnl= Sp3
20 Maximum Likelihood (ML) ML tree lnl= N i = 1 log(l i Tree) (Slide from Derrick Zwickl)
21 Maximum Likelihood ( 最大似然法 )
22 Maximum Likelihood ( 最大似然法 ) A T Sp1=A Sp2=T 3 unrooted trees C A G T Sp3=C Sp4=G G C A G T C
23 Likelihood ( 似然值 ) A C T G Y (1) A C T G T A X L (1) =π A * P AA *P AC *P AT *P TT *P TG (16) A C T G G C L (16) =π G * P GA *P GC *P GC *P CT *P CG L(site1 tree) =L (1) + L (2) + + L 16
24 Likelihood ( 似然值 ) Sp1=A C Sp2=T T Sp3=C C Sp4=C C A C T G X Y L(Data tree) = L(site1 tree) * L(site2 tree) * L(siten tree) Log L(Data tree) = Log L(site1 tree) + Log L(site2 tree)..+log L(siten tree) lnl= N i = 1 LnL i
25 Maximum Likelihood (ML) ML tree lnl= N i = 1 log(l i Tree) (Slide from Derrick Zwickl)
26 Maximum Likelihood (ML):gap/missing/ambiguous characters Sp1= A Sp2= G 1 3 Sp3= G Sp4= C Sp5= G Sp1= A Sp2= G A T Sp3= G C Sp4= C Sp5= G - C
27 Site-wise log likelihood support (SLS) 1 lnl= N i = 1 SLS i 27
28 Incongruence: Ascoideaceae ( 酱霉科 ) ML BS=82 ML BS=100 1,559-gene and 38-taxon Riley et al. PNAS ,233-gene and 86 yeasts Shen et al. G3 2016
29 Site-wise log likelihood support (SLS) T1 T2 SLS 1 =log(p 1 T1) - log(p 1 T2)=
30 Gene-wise log likelihood support (GLS) GLS 1 =lnl(g 1 T1) - lnl(g 1 T2)=
31 ΔGLS ΔGLS plot DPM1 A single gene displays very strong difference in gene-wise log likelihood scores for T1 against T2. 31
32 ΔGLS Removal DPM1 32
33 Removal of the strongest gene ML BS=100 ML BS=46 1,233-gene (T1) Shen et al. G ,232-gene (T2) Shen et al. G Removal of the strongest gene witched the ML tree s support from T1 to T2 33
34 Contentious relationships in phylogenomic studies can be driven by a handful of genes 34
35 Improved sampling 35
36 Sampling of 3 Additional Taxa Breaks the Long Branch... GLS (DPM1) = 340 GLS (DPM1) = ~20 Phaffomycetaceae Saccharomycetaceae / Saccharomycodaceae 36
37 Three large phylogenomic data matrices Plant:103 taxa and 674 gens Wickett et al. PANS 2014 Animal: 58 taxa and 4682 genes Chen et al. Syst Biol 2015 Fungi: 86 yeasts and 1233 genes Shen et al. G3 2016
38 ΔGLS plot (17 branches) 6 branches show a single or a handful of genes display very strong ΔGLS 38
39 Phylogenomics 39 Delsuc et al. 2005
40 ΔSLS Difference in Site-wise log likelihood support (Δ SLS) within individual gene Sites 40
41 Conclusions A tiny amount of data in very large phylogenomic data matrix can drive the resolution of specific internodes Why it happens? Wrong sequence, paralogs, HGTs Distribution of phylogenetic signal for each of the main alternative hypotheses Majority of genes support your results? 41
