A model depicting the spatio-temporal and selective expression pattern of the genes involved in RFOs accumulation in peanuts. The genes shows upregulation (red) at early stage of seed development (S1) in high RFOs varieties and at later stage (S1) in low RFOs varieties. The RFOs pathway is represented with key genes, namely, galactinol synthase (GolS), raffinose synthase (RS) and stachyose synthase (SS) , which are highlighted (
).
Alpha galactosidase (AGAL) and beta fructofuranosidase (BFLUCT) are the RFOs degrading enzymes. All the genes are highly expressed in the seeds but AhRS4 also shows expression in leaves. The location of these genes is represented by the chromosome number as superscript to the genome, A (
)
or B (
).
These genes can be targeted to develop low RFOs peanut varieties.
