Overexpression of PIN7 suppressed the JA-mediated extra-xylem phenotype.
Cross-sectional images of the roots of 35S::PIN7 grown in JA-untreated (Con) and -treated conditions (JA) for 7 days (JA, 10 μM methyl jasmonate). (b) Quantification of extra xylem formation in these plants. Percentages were calculated by dividing the number of plants with extra xylem by total number of plants observed (n > 20).
