Phytate is the major storage form of organic phosphorus in soils and plant seeds, and phosphorus (P) in this form is unavailable to plants or monogastric animals.In the present study, the phytase genes phyA and appA were introduced into Brassica napus cv Westar with a signal peptide sequence and CaMV 35S promoter, respectively.Three independent tra
Brain basis of cognitive resilience: Prefrontal cortex predicts better reading comprehension in relation to decoding.
ObjectiveThe ultimate goal of reading is to understand written text.To accomplish this, children must first master decoding, the ability to translate printed words into sounds.Although decoding and reading comprehension are highly interdependent, some children struggle to decode but comprehend well, whereas others with good decoding skills fail to
Substitution as a mechanism for genetic robustness: the duplicated deacetylases Hst1p and Sir2p in Saccharomyces cerevisiae.
How duplicate genes provide genetic robustness remains an unresolved question.We have examined the duplicated histone deacetylases Sir2p and Hst1p in Saccharomyces cerevisiae and find that these paralogs with non-overlapping functions can provide genetic robustness against null mutations through a substitution mechanism.Hst1p is an NAD(+)-dependent
