| 2.7.1.4 | malfunction |
RNAi-mediated reduction of FRK2 activity in developing wood of hybrid aspen lead to the accumulation of soluble neutral sugars and a decrease in hexose phosphates and UDP-glucose. Reduced FRK2 activity also leads to thinner fiber cell walls with a reduction in the proportion of cellulose |

| 2.7.1.4 | physiological function |
cotton plants transformed with a tomato fructokinase gene (FRK1) under the control of the CMV 35S promoter show increased fibre and leaf FRK activity over nonexpressing nulls, but not improved fibre length and strength. Compared with the nulls, FRK1 plants yield 13-100% more seed-cotton mass per boll and more bolls per. The enhanced yield is related to a greater seed number per boll for FRK1 plants. Photosynthetic rates are not appreciably different among genotypes. However, more area per leaf and leaf number for FRK1 plants than for nulls enhances the capacity for C gain. Larger leaf areas for FRK1 plants are associated with larger stem diameters |

| 2.7.1.4 | physiological function |
suppression of isoform FRK3 reduces the stem xylem area, stem and root water conductance, and whole-plant transpiration, with minor effects on plant development. Suppression of FRK3 accompanied by partial suppression of isoform FRK2 induces significant growth-inhibition effects, including the wilting of mature leaves. These growth effects are imposed primarily by the leaves, whose petioles have unlignified, thinwalled xylem fibers with collapsed parenchyma cells around the vessels |

| 2.7.1.4 | 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 |

| 2.7.1.4 | malfunction |
specific suppression of SlFRK1 reduces water transport in stems, but had no other anatomical or phenotypic effects |

| 2.7.1.4 | 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 |

| 2.7.1.4 | 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 |

| 2.7.1.4 | metabolism |
to enter metabolism, fructose is phosphorylated by a fructokinase |

| 2.7.1.4 | malfunction |
single knockouts of the fructokinase mutants do not exhibit any unusual phenotype. Double-mutants of AtFRK6 and AtFRK7 show normal growth in soil, but yield dark, distorted seeds. The double-mutants exhibit reduced fatty acid synthesis |
