General Information

General Information Comment Organism
malfunction combined suppression of SlFRK1 and SlFRK2 severely inhibits plant growth and an anatomical analysis reveals a reduction in secondary xylem area and distorted phloem fibers characterized by thin cell walls and reduced lignification Solanum lycopersicum
malfunction specific suppression of SlFRK1 reduces water transport in stems, but had no other anatomical or phenotypic effects Solanum lycopersicum
physiological function fructose phosphorylation in the vascular tissues is highly important for cell-wall metabolism. SlFRK2 and SlFRK3 are involved in vascular tissue development and affects the shape, size, and cell-wall width of xylem vessels and xylem fibers Solanum lycopersicum
physiological function SlFRK1 is involved in vascular tissue development and hydraulic conductivity in tomato plants. SlFRK1 is important for normal phloem fiber development together with SlFRK2 Solanum lycopersicum
