Cancers are characterized by non-random chromosome copy number alterations that presumably contain oncogenes and tumor-suppressor genes (TSGs).The affected loci are often large,making it difficult to pinpoint which genes are driving the cancer.Here we report a cross-species in vivo screen of 84 cA facile forward-genetic screen for Arabidopsisexpanded the lon2 suppressor screen.This effort yielded 21 alleles of 6 ATG genes,including 1 atg3,2atg2,2 atg5,2atg18a,3atg16,and11atg7 mutants.We did not recover atg11 or nbr1 mutants in our screen,but using reverse genetics,we demonstrated that loss of ATG11 incompletely suppresses lon2 phenotypes and that the selec-A Suppressor/Enhancer Screen in Drosophila Reveals a Role Nov 01,2011 screens suppressor genetics#0183;A suppressor/enhancer screen to identify WntD pathway components.It is of interest to determine how the WntD ligand signals to influence PGC migration and other biological processes.To identify components of the WntD signaling pathway,we performed a screen for suppressors and enhancers of the lethality caused by maternal overexpression of WntD .
