What is the lowest number of genes with less than 927,303 base pairs in Acidobacteria Bacterium?
CREATE TABLE "group" (
  "species" text,
  "strain" text,
  "type" text,
  "base_pairs" real,
  "genes" real
);
SELECT MIN("genes") FROM "group" WHERE "base_pairs"<'927,303' AND "species"='acidobacteria bacterium';
