Q: Given a passage with a question and an answer to that question, classify if the answer actually answers the question into 'yes' or 'no'. Output 'yes' if the answer answers the question and output 'no' if the answer does not answer the question.
Question: Is [ Expression of the hrcC , hrpE and hpa3 genes regulated by the hrpG and hrpX genes in a rice pathogen Xanthomonas oryzae pv . oryzicola ]?
Answer: This indicated that the expression of the hrcC, hrpE and hpa3 genes was not regulated by the hrpG and/or hrpX genes, but the expression of the hrcT gene was negatively controlled by the hrpG gene. Thus, we postulated that the expression of key type- III secretion (T3S) apparatus components was controlled by an unknown signaling pathway, which may facilitate our further understanding on the formation of the T3S machine.
A:
no
