Cassava root rot (CRR) disease associated with a complex of soil pathogens has caused great yield losses in the crop. The objective of the current work was to obtain insights about the genetic architecture of CRR resistance caused by Fusarium (dry root rot ? DRR), Phytophthora (soft root rot ? SRR) and Botryosphaeriaceae (black root rot ? BRR) species, using genome-wide association studies (GWAS). Phenotyping data of 263 accessions (artificial inoculation) and 14 094 single-nucleotide polymorphisms (SNP) (missing data <0·10 and minor allele frequency >0·05) were used. The severity of CRR in peel and pulp was variable among accessions, but the pathogens that caused DRR were more aggressive. Broad-sense heritability (h2g ) was of medium magnitude for all groups of resistances for pathogens, with variation from 0·16 ± 0·019 (Fspp Pulp) to 0·31 ± 0·028 (Fspp Peel). The kinship matrix was used to correct for stratification as well as for clustering the accessions. Overall, this analysis showed that there was no relationship between agronomic traits and resistance to CRR and the four clusters obtained from kinship matrix. The GWAS identified 38 significant SNPs, of which eight and 22 are related to the severity of DRR in the pulp and peel, respectively. The other eight SNPs were associated with SRR-peel (1), SRR-pulp (1), BRR-peel (3) and BRR-pulp (3). Half of the SNPs associated with CRR resistance have functional annotations related to defence and response to pathogen attack as well as general cellular processes. The current study revealed that resistance to CRR is controlled by multiple loci with small effects, and significant SNPs can be used to identify putative genes that control these traits.

O crestamento bacteriano comum (CBC) se destaca entre as doenças bacterianas do feijoeiro-comum (Phaseolus Vulgaris L.) devido a sua ampla incidência no âmbito nacional. A doença é incitada por Xanthomonas axonopodis pv. phaseoli (Xap) e os danos maiores ocorrem em regiões com climas quentes e úmidos. O objetivo deste trabalho foi avaliar a reação de 36 cultivares a diferentes isolados de Xap em condições de campo e estimar a produção de cada genótipo comparando-a com a severidade da doença. Os genótipos que obtiveram notas mais baixas e por conseqüência mostraram-se mais resistentes foram: CNFP 10120, CNFP 10132, BRS Esplendor, CNFC 10438, BRS Timbó e BRS Pitanga. Os genótipos mais suscetíveis foram BRS 9435 Cometa, BRS Expedito, BRSMG Talismã, BRSMG Realce, WAF 75 e Ouro Branco. |
