In response to infection by the rust pathogen Uromyces fabae the different tissues of broad bean (Vicia faba L.) showed varied pattern of amino acid metabolism; some of them being exclusively present in a particular region only. In the inflorescence tissue, for example, tryptophan, glycine, aspartic acid, serine, proline, and arginine were present. In the stem, however, the amino acids, present during and after infection, were tryptophan, serine, glutamine, homoserine, and dl-alanine. Post-infectionally induced amino compounds, lysine, histidine, vomoserine, proline, tyrosine and dl-threonine, were found in the leaves; in the petiole serine and histidine were the only two such amino acids. Out of these amino acids only histidine and proline, with their specific presence and activity, encouraged uredospore differentiation. L-cysteine, too, by being actively utilized, served as promoter of uredosporulation. Asparagine and methionine showed moderate to heavy depletion during bean tissue infection. On the other hand, l-leucine/isoleucine, beta-alanine, valine, and glutamic acid showed moderate to pronounced increase during pathogenic establishment. Concomitant to uredospore differentiation there was a drastic lowering in the amount of sucrose in leaf and petiole tissue. The amount of glucose also declined during pathogenesis.
针对锈病病原体蚕豆单胞锈菌（Uromyces fabae）的感染，蚕豆（Vicia faba L.）的不同组织呈现出不同的氨基酸代谢模式；其中一些仅在特定区域存在。例如，在花序组织中，存在色氨酸、甘氨酸、天冬氨酸、丝氨酸、脯氨酸和精氨酸。然而，在茎中，感染期间及感染后存在的氨基酸是色氨酸、丝氨酸、谷氨酰胺、高丝氨酸和dl-丙氨酸。在叶片中发现了感染后诱导产生的含氮化合物，赖氨酸、组氨酸、3-羟基天冬氨酸、脯氨酸、酪氨酸和dl-苏氨酸；在叶柄中，丝氨酸和组氨酸是仅有的两种此类氨基酸。在这些氨基酸中，只有组氨酸和脯氨酸，凭借其特定的存在和活性，促进了夏孢子分化。L-半胱氨酸通过被积极利用，也起到了促进夏孢子形成的作用。在蚕豆组织感染期间，天冬酰胺和蛋氨酸呈现出中度到重度的消耗。另一方面，在病原菌定殖期间，L-亮氨酸/异亮氨酸、β-丙氨酸、缬氨酸和谷氨酸呈现出中度到显著的增加。与夏孢子分化同时发生的是，叶片和叶柄组织中的蔗糖含量急剧下降。在发病过程中，葡萄糖含量也下降了。
