Sucrose transport involves in disease response to Xanthomonas oryzae pathovar oryzae.

Sugar acts as an important nutrient for plant development. Previously, we reported that Oryza sativa DNA BINDING WITH ONE FINGER 11 (OsDOF11) plays a crucial role in sucrose transport by binding promoters of sucrose transporter genes, OsSUT1, OsSWEET11, and OsSWEET14. Meanwhile, sucrose transport activity abnormal also involved susceptibility to infection of Xanthomonas oryzae pathovar oryzae (Xoo) by OsSWEET genes. Here, we provid an addendum, that OsDOF11 expression pattern in spikelet development stage, and transcript levels of OsSWEET12, OsSWEET13, OsSWEET15, and OsSWEET16 in the mutants of OsDOF11 at different developmental stages. This information further supplied a new insight that sucrose transport activity mediated susceptibility to Xoo infection.
