A natural gene drive element confers speciation in rice

Y. Li, S. Liu and R. Shen,  Chinese Science Bulletin,  68:3400-3402. 2023.
For a long time, although many important advances have been made in the field of rice hybrid sterility, the specific molecular mechanism behind the "killer-protector"/ "poison-antidote" model has been unclear. Recently, the team of Academician Wan Jianmin of Nanjing Agricultural ...

The role of conflict in shaping plant biodiversity

J. M. Coughlan,  New Phytologist,  2023.
Although intrinsic postzygotic reproductive barriers can play a fundamental role in speciation, their underlying evolutionary causes are widely debated. One hypothesis is that incompatibilities result from genomic conflicts. Here, I synthesize the evidence that conflict generates ...

Standard deviations: The biological bases of transmission ratio distortion

L. Fishman and M. McIntosh,  Annual Review of Genetics,  53:347-372. 2019.
The rule of Mendelian inheritance is remarkably robust, but deviations from the equal transmission of alternative alleles at a locus [a.k.a. transmission ratio distortion (TRD)] are also commonly observed in genetic mapping populations. Such TRD reveals locus-specific selection ...

TSETSE GENETICS: Contributions to Biology, Systematics, and Control of Tsetse Flies

R. H. Gooding and E. S. Krafsur,  Annual Review of Entomology,  50:101-123. 2005.
Tsetse flies (Diptera: Glossinidae) constitute a small, ancient taxon of exclusively hematophagous insects that reproduce slowly and viviparously. Because tsetse flies are the only vectors of pathogenic African trypanosomes, they are a potent and constant threat to humans and ...
