Qualitative and quantitative estimation of a proteinaceous chymotrypsin inhibitor in tissues of potato plants has revealed a transitory existence in all tissues except xylem, flowers, and seeds, where the inhibitor was not found. The distribution pattern in both aerial tissues and in tubers during development and senescence suggests that the concentrations of this protein in all tissues are influenced by meristematic regions of the plants. The transitory existence coinciding with breaking of apical dominance suggests that in the potato plant the protein may have some role in the process of establishing and maintaining meristematic tissue. A search for the protein in other Solanaceae species and in plants from non-related species has proven unsuccessful.
对马铃薯植株组织中一种蛋白质胰凝乳蛋白酶抑制剂的定性和定量估计表明,除木质部、花朵和种子外,所有组织中都存在这种抑制剂。在发育和衰老过程中,这种蛋白质在地上组织和块茎中的分布模式表明,所有组织中这种蛋白质的浓度都受到植物分生组织区域的影响。这种与顶端优势解除同时存在的短暂存在表明,在马铃薯植物中,该蛋白质可能在建立和维持分生组织组织的过程中发挥作用。在其他茄科植物和非相关物种的植物中寻找这种蛋白质的尝试都没有成功。
