Symbioses and Stress: Joint Ventures in Biology (Cellular Origin, Life in Extreme Habitats and Astrobiology)
Format: PDF / Kindle (mobi) / ePub
Symbioses and Stress examines how organisms in tight symbiotic associations cope with abiotic and biotic stress. Presenting new findings on symbioses by experts and leading scholars in the field, this volume complements courses and lectures in biology and genetics.
components or else replacing pre-existing eukaryotic counterparts. A comprehensive examination of the cyanobacterial contribution to Arabidopsis (Martin et al., 2002) estimated that ~18% or ~4,500 genes of the nucleus genome were derived from the endosymbiont. However, only about 1,300 of these encode proteins targeted to the plastid. However, given the size of the plastid genome and the complexity of the plastid proteome, it is clear that development of a targeting and import mechanism was also

poor homology with the Aequorea victoria GFP (17.8% of identical residues; Wiedenmann et al., 2004). Their functions are not fully understood, but have been described as photoprotective in high-light conditions by scattering the light reaching the coral (Salih et al., 2000), or conversely, by enhancing photosynthesis in low-light conditions (Schlichter and Fricke, 1990; see section 3.3). In addition, it has been shown that GFPs might display antioxidant activity. Indeed, it has recently been
