长柄链果蕨克拉克是苦苣苔科的一个物种，其特征是营养体无茎。它的营养体不是由茎的顶端分生组织发育而成的，而是由一片子叶的连续的、居间的生长而成的。β-葡萄糖基Yariv苯基糖苷（β-D-Glc）3选择性结合一类称为阿拉伯半乳聚糖蛋白（AGP）的细胞表面相关蛋白聚糖和糖蛋白。种子和幼苗处理。具有（β-D-Glc）3诱导的表型变异体被认为具有系统发生学意义，因为它们复制了其他可能更原始的链果属物种以及其所属科中其他属物种的形态特征（表型模仿）。这些结果与以前用S.使用含羟脯氨酸蛋白（Hyp-proteins）的抗代谢物的prolixus。用α-半乳糖基苯基糖苷治疗，一种不结合…
Streptocarpus prolixus C.B. Clarke is a species in the family Gesneriaceae characterized by an acaulescent vegetative body. Instead of a stem bearing leaves developing from a shoot apical meristem, its vegetative body derives from the continued, intercalary growth of one of its cotyledons. β-glucosyl Yariv phenyglycoside (β-D-Glc)3 selectively binds a class of cell surface associated proteoglycans and glycoproteins known as arabinogalactan-proteins (AGPs). Treating seeds and seedlings of S. prolixus with (β-D-Glc)3 induced phenovariants considered phyogenetically significant because they copied morphological features (phenocopied) characteristic of other, presumably more primitive species of Streptocarpus as well as species in other genera in the family to which it belongs. These results paralleled those obtained in earlier experiments with S. prolixus using antimetabolites of hydroxyproline-containing proteins (Hyp-proteins). Treatment with α-galactosyl phenylglycoside, a Yariv reagent that does not bind...
