Nitric oxide (NO) is currently regarded as a signal molecule involved in plant cell differentiation and programmed cell death. Here, we investigated NO production in the differentiating xylem of Zinnia elegans by confocal laser scanning microscopy to answer the question of whether NO is produced during xylem differentiation. Results showed that NO production was mainly located in both phloem and xylem regardless of the cell differentiation status. However, there was evidence for a spatial NO… CONTINUE READING
