Abundance changes in proteins related to phenylpropanoid biosynthesis and porphyrin and chlorophyll metabolism. a. Overview of phenylpropanoid biosynthesis pathways in Medicago sativa L. Enzyme abbreviations are as follows. Phenylalanine ammonia-lyase-like protein (PAL), cytochrome P450 family cinnamate 4-hydroxylase (C4H), caffeic acid O-methyltransferase (COMT), 4-coumarate: CoA ligase-like protein (4CL), monoglyceride lipase-like protein (MGL), HXXXD-type acyl-transferase family protein (HCT), caffeoyl-CoA 3-O-methyltransferase (CCoAOMT), cinnamyl alcohol dehydrogenase-like protein (CAD), horseradish peroxidase-like protein (HRP), glycoside hydrolase family 1 protein (GH1), and cytochrome P450 family monooxygenase (F5H); b. Overview of porphyrin and chlorophyll metabolism pathways in M. sativa L. Enzyme abbreviations are as follows. Porphobilinogen deaminase (PBGD), uroporphyrinogen decarboxylase (UPOD), bacteriochlorophyll synthase (BchG), red chlorophyll catabolite reductase (RCCR), magnesium-chelatase subunit ChlI, and magnesium-protoporphyrin IX monomethyl ester cyclase (MPEC). The circles represent proteins identified in stems, whereas the squares represent proteins identified in leaves. Red indicates upregulation, white indicates no significant changes, and green indicates downregulation in M genotype alfalfa
