ALT Fig 7. ShyA overexpression rescues morphological defects associated with carboxypeptidase insufficiency in E. coli.
(A) E. coli strains CS109 and Δ4 (CS109 ΔdacA ΔdacB ΔdacC ΔpbpG) containing either an empty vector (pHL100) or a vector containing an IPTG-inducible copy of ShyA (pHL100-ShyA) were incubated overnight at 37°C in LB medium with 0.2% glucose, sub-cultured 1:100 in LB and incubated for 2 hours, then back-diluted 1:100 in LB and grown for an additional 2 hours. 1 mM IPTG or 0.2% glucose was added to the cultures, phase contrast images were taken 3 hours after induction. (B) Microscopy images were segmented with Omnipose and analyzed for area, length, and width with MicrobeJ. Statistical significance was assessed via Welch’s t-test. ****, P < 0.0001.

Dorsal closure and germband retraction defects of rheaABS2/ABS3 compared to rheaABS3/ABS3 using chi-square test: *P<0.05; all genotypes n>30. (K) Number of detached muscles per embryo. Floating bar chart representing minimum and maximum value per genotype (n>10). Mean value represented by a solid line.

This recent study from researchers at @AarhusUni_int and @Harvard discusses using TRAILS for tree reconstruction of ancestry using incomplete lineage sorting. plos.io/3wUeniH
ALT Fig 4. The posterior probability can be used to detect deviations from the neutral expectation.
(A) Posterior probability of the second coalescent event for a simulated 200 kb region containing a positively selected variant at position 100 kb that arises in interval S0, represented by a triangle. The true simulated coalescent times are plotted as green horizontal lines. (B) Mean posterior probability for each second coalescent interval (purple), and the empirical true proportion of sites for each interval (green) for 20 simulated replicates with a selective sweep, using the same model as in (A). The theoretical neutral expectation is plotted as a black dashed line, and time intervals are adjusted so that all intervals have equal probability of observing a coalescent event. Continuous vertical lines represent mean values of the simulations. (C) Same as in (B), but for a neutrally evolving region, using the same model as in Fig 3.

In this recent study, researchers show that cLD reveals an increased genetic association between genes in 3D chromatin interactions, a phenomenon recently reported negatively by calculating standard LD between common variants: plos.io/3tC0Lah
ALT Fig 1. Illustration of the idea of a) cMAF and b) cLD.
An example to show the calculation of cLD, inspired by cMAF. a) Out of six haplotypes, there are two [1, 4] who have mutations in region A. Therefore, the cMAF P(A) for region A is 2/6 = 0.33. b) There are three haplotypes [3, 4, 5] who have mutations in region B and the cMAF P(B) for region B is 3/6 = 0.50. If one considers regions A and B together, there is one individual with mutations in both regions: [4]. Thus, the P(AB) is 1/6 = 0.17. Finally, by yielding P(A), P(B) and P(AB) into the standard formula of LD we have cLD = 0.375. (This is only an illustrating example with 6 haplotypes. In practice, the variants contributing to cMAF or cLD are rare ones with MAF < 0.5%.
