From: RNA-seq analysis of short fiber mutants Ligon-lintless-1 (Li 1 ) and – 2 (Li 2 ) revealed important role of aquaporins in cotton (Gossypium hirsutum L.) fiber elongation

Figure 6

A possible mechanism of termination of fiber elongation in the Li 1 and Li 2 mutants. The high osmotic pressure in fiber cell of WT and high level of expression of aquaporins facilitates influx of water that contributes to the rapid fiber elongation. The higher accumulation of ions in fiber cells of Li 1 Li 2 may be the result of limited uptake of water. The reduced influx of water (due to low concentration of sugars and low expression of aquaporins) causes the reduced fiber elongation in the Li 1 Li 2 mutants.
