A ameixeira e atacada por uma doenca denominada rscaldadura das folhas, causada por um microorganismo conhecido como bacteria tipo rickettsia, que provoca a morte de ramos e, finalmente, a morte de plantas. Desde a constatacao da escaldadura das folhas da ameixeira, tem-se observado acentuado declinio de pomares localizados nas regioes produtoras dos Estados do Parana, Santa Catarina e Rio Grande do Sul. Esta doenca e disseminada atraves de material propagativo infectado, sendo, portanto, a utilizacao de mudas sadias um fator essencial para nova expansao desta cultura, no Brasil. Por outro lado, a cultura de meristemas e um metodo eficiente para a eliminacao desta e outras doencas que atacam os vegetais. No entanto, no caso especifico da ameixeira, a micropropagacao de material sadio, alem de ser onerosa, apresenta baixa taxa de multiplicacao e alongamento de gemas. |

Mycobacterium bovis is an important animal pathogen worldwide that parasitizes wild and domesticated vertebrate livestock as well as humans. A comparison of the five M. bovis complete genomes from the United Kingdom, South Korea, Brazil, and the United States revealed four novel large-scale structural variations of at least 2,000 bp.Acomparative phylogenomic study including 2,483 core genes of 38 taxa from eight countries showed conflicting phylogenetic signal among sites. By minimizing this effect,we obtained a tree that better agreeswith sampling locality. Results supported a relatively basal position of African strains (all isolated from Homo sapiens), confirming that Africa was an important region for early diversification and that humans were one of the earliest hosts. Selection analyses revealed that functional categories such as ?Lipid transport and metabolism,? ?Cell cycle control, cell division, chromosome partitioning? and ?Cell motility? were significant for the evolution of the group, besides other categories previously described, showing importance of genes associated with virulence and cholesterolmetabolism in the evolution of M. bovis. PE/PPE genes,many ofwhich are known to be associated with virulence, were major targets for large-scale polymorphisms, homologous recombination, and positive selection, evincing for the first time a plethora of evolutionary forces possibly contributing to differential adaptability in M. bovis. By assuming different priors, US strains originated and started to diversify around 150?5,210 ya. By further analyzing the largest set of US genomes to date (76 in total), obtained from 14 host species,we detected that hosts were not clustered in clades (except for a few cases), with some faster-evolving strains being detected, suggesting fast and ongoing reinfections across host species, and therefore, the possibility of new bovine tuberculosis outbreaks.
