Application

Application	Comment	Organism
additional information	role of FRK2 in pre- and post-fertilization events, overexpression of FRK2 leads to the production of fruits with a severely reduced number of seeds, and leads to changes in the expression of the class D floral homeotic gene ScFBP11, suggesting that FRK2 kinase may interact, directly or indirectly, with the FBP7/11 pathway that directs establishment of ovule identity	Solanum chacoense

Cloned(Commentary)

Cloned (Comment)	Organism
transgenic plants carrying the sense or antisense construct of FRK2	Solanum chacoense

Protein Variants

Protein Variants	Comment	Organism
additional information	FRK2-S2, FRK2-S17, FRK2-S5, FRK2-S7, FRK2-S9, and FRK2-11 mutant sense lines reveal that overexpression of FRK2 produces smaller than normal fruits containing fewer seeds, FRK2-S2 and FRK2-S17 mutant sense lines reveal that overexpression of FRK2 leads to transformation of ovules into carpelloid structures, FRK2-S20 mutant sense line shows complete co-suppression for FRK2, plants containing the antisense construct show reduced ScFRK2 mRNA levels compared with the wild-type	Solanum chacoense
