Roundup Sudden bacterial death syndrome

such a simple model will not work, because the mesh of oocyte microtubules is largely unpolarized. Instead, bicoid mRNA picks up transport factors in the nurse cells, before entering the oocyte and using those factors to mediate anterior localization, possibly on a polarized subset of microtubules. Without the factors, the mRNA can move on Exuperantia from nurse cell helps bicoid RNA (green) move to the oocyte anterior. Th eu rk au f/E ls ev ie r
