A linear stress strain analyzer was used to determine the effects of inhibitors of RNA and protein synthesis on auxin-induced increases in cell wall extensibility. With etiolated soybean hypocotyl, maize mesocotyl and Avena coleoptile sections and light-grown pea internode sections, inhibition of RNA synthesis resulted in inhibition of auxin-induced extensibility changes and cell expansion. The results with both actinomycin D and cycloheximide support an earlier conclusion that unstable cell constituents, presumably enzymes, are essential for cell wall loosening induced by auxin as well as for cell elongation.
使用线性应力应变分析仪来确定RNA和蛋白质合成抑制剂对生长素诱导的细胞壁伸展性增加的影响。对于黄化大豆下胚轴、玉米中胚轴和燕麦胚芽鞘切段以及光照生长的豌豆节间切段，RNA合成的抑制导致生长素诱导的伸展性变化和细胞扩张受到抑制。放线菌素D和环己酰亚胺的结果都支持了一个较早的结论，即不稳定的细胞成分，可能是酶，对于生长素诱导的细胞壁松弛以及细胞伸长是必不可少的。
