Yaylacılık ülkemizde önemli bir gelenek olup, bu araştırma, 2014-2015 vejetasyon döneminde, Trabzon İli Düzköy İlçesi Yaylası (Kamema)’nın yaş ot ve botanik kompozisyonları ile birlikte florası incelenmiştir. Yayla (Kamena) çayırlarının verimleri 2.450-3.275 kg da-1 arasında değişmiş ağırlık esasına göre ise % 73 buğdaygiller + 12 baklagiller 15 diğer familyalardan oluşmuştur. Yapılan floristik...

In this paper, we analyze a satellite-DNA family, the RAYSI family, which is specific of the Y chromosomes of Rumex acetosa, a dioecious plant species with a multiple sex-chromosome system in which the females are XX and the males are XY(1)Y(2). Here, we demonstrate that this satellite DNA is common to other relatives of R. acetosa, including Rumex papillaris, Rumex intermedius, Rumex thyrsoide...

Diversity and distribution of exotic plant taxa in Kosciuszko National Park in south-eastern Australia were reviewed based on 1103 records of exotics from 18 vegetation surveys conducted between 1986 and 2004. 154 taxa from 23 families were recorded in the alpine to montane zones, with eleven taxa in the alpine, 128 taxa in the subalpine and 69 taxa in the montane zone. Nearly all taxa were ass...

Submergence-induced ethylene synthesis and entrapment were studied in two contrasting Rumex species, one flood-resistant (Rumex palustris) and the other flood-sensitive (Rumex acetosa). The application of a photoacoustic method to determine internal ethylene concentrations in submerged plants is discussed. A comparison with an older technique (vacuum extraction) is described. For the first time...

Natural plants products are one of the famous and commonly utilized remedies used in fighting diseases. This study was conducted to evaluate antioxidant activity of plants commonly used in Palestine (Urtica urens, Rumex cyprius and Borago officinalis). Free radical scavenging activity method was evaluated by using 2,2-diphenyl-1-picryl-hydrazyl-hydrate. The result show that the overall antioxid...

Mitochondrial diseases are severe and largely untreatable. Owing to the many essential processes carried out by mitochondria and the complex cellular systems that support these processes, these diseases are diverse, pleiotropic, and challenging to study. Much of our current understanding of mitochondrial function and dysfunction comes from studies in the baker’s yeast Saccharomyces cerevisiae. ...
