Seven different MYB-related genes have been isolated from a genomic Arabidopsis library with probes based on MYB DNA-binding motifs. The predicted amino acid sequence of these genes showed high similarity in the MYB domain but outside this region virtually no similarities were found. The set of MYB-related genes was used to identify differentially expressed genes following the transfer of etiolated seedlings to light. This differential screen resulted in the selection of the ATM4 gene which is induced by light within one hour of exposure of etiolated or dark-adapted seedlings.  相似文献

Population geneticists often use multiple independent hypothesis tests of Hardy–Weinberg Equilibrium (HWE), Linkage Disequilibrium (LD), and population differentiation, to make broad inferences about their systems of choice. However, correcting for Family‐Wise Error Rates (FWER) that are inflated due to multiple comparisons, is sparingly reported in our current literature. In this issue of Molecular Ecology Resources, perform a meta‐analysis of 215 population genetics studies published between 2011 and 2013 to show (i) scarce use of FWER corrections across all three classes of tests, and (ii) when used, inconsistent application of correction methods with a clear bias towards less‐conservative corrections for tests of population differentiation, than for tests of HWE, and LD. Here we replicate this meta‐analysis using 205 population genetics studies published between 2013 and 2018, to show the same continued disuse, and inconsistencies. We hope that both studies serve as a wake‐up call to population geneticists, reviewers, and editors to be rigorous about consistently correcting for FWER inflation.  相似文献

Predation is a well‐known problem in South Africa with large losses in the small and large livestock sectors. Predation in the wildlife ranching industry has also become more of a concern, as the financial losses due to predation on valuable antelope species are large. Predation data for small, large, and scarce/colour‐variant antelope species were collected using a structured questionnaire from wildlife ranchers in the Limpopo province, South Africa. We explore the factors that influence predation on these species by determining whether the perceptions of predation and consequent managerial decisions affect predation. The use of nonlethal control methods can be successfully employed to reduce the probability of predation occurrences, however, a combination of lethal and nonlethal control methods were used to reduce the level of predation. The type of antelope species will determine the type of predation control method to be employed. Therefore, the antelope species should be taken into account when making predation management decisions.  相似文献
