Temperature and palaeolake evolution during a Middle Pleistocene interglacial–glacial transition at the Palaeolithic locality of Schöningen, Germany

Boreas, Volume 53, Issue 4, Page 504-524, October 2024.
Biological proxy analyses, element composition, and stable isotope ratios at the Lower Palaeolithic locality of Schöningen provide evidence for repeated variations in climate, hydrology and catchment vegetation cover during MIS 9. Quantitative temperature reconstructions with the Mutual Ostracod Temperature Range method show colder winter temperatures ...

Phenylalanine ammonia‐lyases and 4‐coumaric acid coenzyme A ligases in Chara braunii, Marchantia polymorpha, and Physcomitrium patens as extant model organisms for plant terrestrialization

The Plant Journal, Volume 119, Issue 6, Page 2797-2815, September 2024.
SUMMARY The conquest of land posed severe problems to plants which they had to cope with by adapting biosynthetic capacities. Adaptations to respond to UV irradiation, water loss, pathogen and herbivore defense, and the earth's pull were essential. Chemical compounds alleviating these problems can be synthesized by the phenylpropanoid pathway, the core

轮藻科(Characeae)三个属无丝分裂的研究

四川大学学报. 自然科学版, 2008
用Giemsa常规染色法和DAPI(4′,6-diamidino-2-′phenylindole)荧光染色法对轮藻科(Characeae)3个属:乳突丽藻(Nitella papillata)、钝节拟丽藻(Nitellopsis obtusa)和弧枝轮藻(Chara connivens)进行了细胞核无丝分裂研究.结果发现无丝分裂是这几种藻体的主要分裂方式;同种藻不同部位,不同种藻之间,无丝分裂形态有所不同.
