Hormone biosynthesis pathways in tobacco leaf and root. (A) DEPs related to four hormone biosynthesis pathways. (B) DEPs related to the IAA and ABA biosynthesis pathway in tobacco leaf and root. The increased DEPs were marked with an upward red arrow and red colored words, and the decreased DEPs were marked with a downward green arrow and green-colored words. The arrow on the left indicates the DEPs in leaf, and the arrow on the right indicates the DEPs in root.
