Unlike vertebrates, plants do not have an adaptive immune system. Nonetheless, plants can launch specific, self-tolerant immune responses and establish immune memory. To promote virulence, pathogens inject effector molecules that target conserved immune signalling hubs into the plant cell. In response,...
Sex determination systems in plants have evolved many times from hermaphroditic ancestors (including monoecious plants with separate male and female flower... Charlesworth,D - 《Heredity》 被引量: 808发表: 2002年 Sexual Selection. Testing the Alternatives Sex determination systems in plants have evolve...
The genome of Populus davidiana, a keystone aspen species, has been sequenced to improve our understanding of the evolutionary and functional genomics of the Populus genus. The Hi-C scaffolding genome assembly resulted in a 408.1 Mb genome with 19 pse
In their struggle for life, plants can employ sophisticated strategies to defend themselves against potentially harmful pathogens and insects. One mechanism by which plants can increase their level of resistance is by intensifying the responsiveness of their immune system upon recognition of selected signa...

An NADH-GOGAT is also present in some plants, as Medicago sativa, but in this case the enzyme is a 200 kDa monomer that appears to derive from the fusion of both bacterial NADPH-GOGAT subunits because it is similar to the large subunit in its N-terminal domain and to the small subunit...

Recent discoveries have extended our knowledge about the mechanistic basis of defence priming and suggest that a primed defence state can be inherited epi-genetically from defence-expressing plants. In this review, we provide an overview of the latest insights about defence priming, ranging from ...
According to the authors, this is one of the first cross-species studies of oxidative stress that compares birds to mammals in an attempt to understand differences in why birds live longer than mammals of the same body mass despite the fact that they have higher rates of energy use. Their ...
