The Asian Xoo strain PXO is then stopped in the degree of fraction B,that is expressed by the absence of colonies in the fractions C and D. On the other hand,Log colonies with the African Xoo strains BAI have already been shown in the fraction C and D (Fig The outcomes of the quantification and of bacterial kinetic show clearly that the African Xoo strain BAI is very different from the among the list of Asian Xoo strain PXO that lights a dominant gene which was the Xa gene. In reality,within the IRBB isogenic line,resistant to both strains,the lesion brought on by BAI was 3 times larger than the one particular caused by PXO. Xa protect against the multiplication and the progression of PXO within the vascular tissues that is expressed around the one particular hand by the reduced quantity of PXO in these tissues and,on the other hand by the total absence of this bacteria cm for the inoculation point. This is in accordance with all the functioning of dominant resistance gene. Alternatively,BAI colonies have been observed even at cm towards the inoculation point. This strain managed to multiply and to colonize the vascular tissues thus major to a significantly less resistant phenotype (Fig The African Xoo strain BAI would hence induced a recessive gene.Fig. Bacteria development for the duration of twelve days right after inoculation of IR rice selection.

In addition,the facts on recognized bacterial blight genesQTLs characterized so far was updated (Additional file and their genetic and physical localization positioned around the reference rice physical map (var Nipponbare). IR has been confirmed as highly resistant to African Xoo strains. The IR x Azucena derived mapping populations segregated for BB resistance. Novel QTLs wereDjedatin et al.

Out of 5,4 QTLs induced by African Xoo strains are various from these induced by the Philippines Xoo strain PXO indicating these strains induced various resistant genes. QTLs induced by African Xoo strains are underlined by the allele in the indica rice IR when Azucena (japonica) may be the donor parent of resistance against Asian Xoo strains except with strain PXO. The genetic characterization of Xoo strains collectively using the current advances in X. oryzae genomic studies indicate that African X. or.
