ABSTRACT - The role of the Co-52 and Co-42  alleles in the early activation of bean immunity against Colletotrichum lindemuthianum is poorly known. Thus, by using the anthracnose-susceptible Sutagao cultivar and the anthracnoseresistant bean G2333, this study aimed to evaluate the presence of the Co-42  and Co-52  alleles by SCAR markers, as well as their role in the respective defense responses, using histochemical tests and differential gene expression. The results showed that the Co-52 allele contributes to defense responses against anthracnose, since susceptible beans with the Co-42 allele and without the Co-52 allele decreased both the number of callose deposits and the accumulation of reactive oxygen species at the fungus attack sites. Additionally, for the Sutagao cultivar, there was a late response of defense-related genes such as PR-1, PR-3 and Pv-POD. The Co-52 allele contributes to induce defense mechanisms in the Phaseolus vulgaris and C. lindemuthianum interaction.

RESUMO - Alelo de resistência Co-52  contribui para induzir a defesa basal contra Colletotrichum lindemuthianum raça 7 -  Em feijoeiro, pouco se conhece sobre o papel dos alelos Co-52 e Co-42  na ativação precoce da imunidade da planta ao fungo Colletotrichum lindemuthianum. Utilizando-se a cultivar Sutagao suscetível à antracnose e o feijoeiro G2333 resistente à antracnose, objetivou-se avaliar a presença dos alelos Co-42  e Co-52  por meio de marcadores SCAR, bem como sua função nas respectivas respostas de defesa, por meio de testes histoquímicos e expressão gênica diferencial. Os resultados mostraram que o alelo Co-52 contribui para as respostas de defesa contra a antracnose, uma vez que os feijoeiros suscetíveis com o alelo Co-42 e sem o alelo Co-52 diminuíram tanto a quantidade de depósitos de calose quanto o acúmulo de espécies reativas de oxigênio nos locais de ataque do fungo. Ademais, para a cultivar Sutagao, houve resposta tardia de genes relacionados à defesa, como PR-1, PR-3 e Pv-POD. O alelo Co-52 contribui para induzir mecanismos de defesa na interação entre Phaseolus vulgaris e C. lindemuthianum.
