Peculiarities of the germline-restricted chromosome of songbird

Peculiarities of the germline-restricted chromosome of songbird

In multicellular organisms, all cells of an individual normally contain the same genetic information and cell differentiation is achieved through regulation of gene expression. There are exceptions, however, where, instead of silencing, certain sequences are permanently deleted from the genome. An interesting example of this programmed DNA elimination has been described in songbirds, where a whole chromosome is lost from somatic cells early on in embryo development and is maintained only in the germ cells. In a paper, which has just been published in the prestigious journal Nature Communications, the team of Radka Reifová from the Department of Zoology, with Stephen Schlebusch as the first author, together with other researchers sequenced this chromosome in two closely related songbird species, providing one of the first insights into the importance and evolutionary dynamics of this peculiar chromosome.

Whole genome multiplication triggers production of evolutionary novel traits

Whole genome multiplication triggers production of evolutionary novel traits

Plants have taken an interesting path in their evolutionary journey. Increasingly, it appears that they can very effectively use the multiplication of chromosome sets and their eventual subsequent reduction to their advantage. How exactly do they do this, and what reproductive, ecological or evolutionary advantages do they derive from it? Patrik Mráz from the Faculty of Science at Charles University is one of the co-authors of a new study that reveals new insights into reproductive strategies in whole genome-multiplying plants.

34th International Biology Olympiad - the Silver and Bronze Ages continue

In Al Ain, on the border with Oman, in the United Arab Emirates (UAE), this year's edition of the Biology Olympiad was extraordinary in many ways. It was originally scheduled to take place in Russia, but given the circumstances, it was already clear last year, in Yerevan, Armenia, that this would not be the case. At the last minute, with the great efforts of Lenka Libusova (Department of Cell Biology, Faculty of Science, Charles University), the chair of the International Biology Olympiad, a new host country was obtained.

How high is the ambient ozone?

How high is the ambient ozone?

Ambient ozone is one of the major pollutants in the air. Its presence is highly undesirable as it is toxic to living organisms and causes damage to forest stands. Monitoring ambient ozone is therefore very important. But how does it behave at different levels close to the surface in an area with relatively clean air? This question has not yet been answered. A team of experts led by Iva Hůnová from the Institute for Environmental Studies at the Faculty of Science of Charles University, together with Marek Brabec and Marek Malý from the Czech Academy of Sciences, set out to find out the results.

Degradation as a synthetic pathway?

Degradation as a synthetic pathway?

Zeolites are extensively studied materials with a high potential for real-life use and industrial applications. However, these applications are often limited by zeolite synthesis, which usually demands harsh conditions and is thus unsuitable for preparing chemically labile materials. Such materials have now been successfully prepared by the research group of Professor Jiří Čejka and Associate Prof. Maksym Opanasenko, in the Department of Physical and Macromolecular Chemistry, and the Charles University Centre of Advanced Materials (CUCAM). Their article has been published in the prestigious Journal of the American Chemical Society (JACS).
