A graphical representation of the number of differentially accumulated proteins in watermelon (Citrullus vulgaris Schrad.) ‘Sambok Honey’ and ‘Speed’ as the scion and bottle gourd (Lagenaria siceraria Stanld.) ‘RS Dongjanggun’ as rootstock seedlings grown under different photon flux densities (25, 50, 75 and 100 μmol m−2 s−1 PPFD).
(A) ‘Sambok honey’ (B) ‘Speed’ as the scion and bottle gourd (Lagenaria siceraria Stanld.) ‘RS Dongjanggun’ as rootstock. Numbers correspond to the protein spots present in 2DE patterns under 25, 50, 75 and 100 μmol m−2 s−1. The overlapped portions with ‘X’ denote absence of proteins. Upward and downward arrows denote increased or decreased protein expression under combined treatments.
