INTEGRITY OF TRANSLATION. “In A. thaliana, on average four gene copies encode for any of the approximately 80 different ribosomal proteins. This redundancy may reflect the importance of maintaining highly productive translation and protein synthesis.” http://bmcevolbiol.biomedcentral.com/articles/10.1186/1471-2148-11-8 View in LinkedIn

PLANT TRANSLATION. “Ten PSGs were found to be ribosomal proteins involved in translation. From an evolutionary point of view, translation is an ancient cellular process, and high selection pressure is expected to act against deleterious mutations, as ribosome functioning affects virtually all cellular processes.” (PSG = positively selected genes). http://bmcevolbiol.biomedcentral.com/articles/10.1186/1471-2148-11-8 View in LinkedIn

FERMENTATIVE GLYCOLYSIS. “In darkness, seagrasses can even be forced to switch to fermentative metabolism. In P. oceanica, malate has previously been shown to accumulate as a consequence of anoxic conditions. Hence, the positive selection of these three glycolysis genes may be associated with seagrass-specific adaptation to anaerobiosis.” http://bmcevolbiol.biomedcentral.com/articles/10.1186/1471-2148-11-8 View in LinkedIn

AQUATIC PLANT GLYCOLYSIS. “With two fructose-bisphosphate aldolase enzymes and a malate dehydrogenase, the list of PSGs contains three enzymes of the glycolysis pathway. This observation may be particularly significant due to the challenges imposed by the O2 sink created by the reductive sediment leading to compensation by internal transport of oxygen from shoot to root tissues during the day cycle.” (PSG = positively selected genes). http://bmcevolbiol.biomedcentral.com/articles/10.1186/1471-2148-11-8 View in LinkedIn

SALT TOLERANCE. “In general, salt-tolerant plants compensate osmotic and ionic imbalances with increased K+ import and the accumulation of compatible solutes. However, genes that are known to facilitate salt tolerance such as the SOS pathway were absent from the orthologous gene clusters and could therefore not be investigated." http://bmcevolbiol.biomedcentral.com/articles/10.1186/1471-2148-11-8 View in LinkedIn
