Interpretive Summary: The native function of OsSULTR3;6 and how it contributes to disease development is unknown. This study characterizes the transport properties, subcellular localization, and potential substrates of this transporter in heterologous systems, as well as investigates its function by examining the phenotype of genome-edited rice lines where the SULTR gene has been knocked out. t rice lines generated by genome editing. This knowledge provides the grounds for a model to understand how OsSULTR3;6 might promote lesion expansion and bacterial exudation during pathogen infection and propagation, providing a target for future control.

Technical Abstract: The type III secreted transcription activator-like effector Tal2g of the rice bacterial leaf streak (BLS) pathogen Xanthomonas oryzae pv. oryzicola promotes lesion development and bacterial exudation through stomata by binding to and upregulating a putative sulfate transporter gene in rice, OsSULTR3;6. To understand how OsSULTR3;6 contributes to disease development, we are characterizing its transport mechanics, subcellular localization, and potential substrates, and phenotyping OsSULTR3;6 knockout lines generated by genome editing. Following a brief introduction to the plant SULTR gene family, this chapter summarizes our findings so far and presents speculative functional models for the role of OsSULTR3;6 in BLS.
