In previous research here, 3,5-diiodo-4-hydroxybenzoic acid (DIHB) was shown to promote the elongation of roots of cress (Lepidium sativum) seedlings growing in light, and to inhibit the auxin-induced production of ethylene in this tissue. Although DIHB is a cofactor for the oxidation of indole-3-acetic acid (IAA) by horse-radish peroxidase, it inhibits the decarboxylation of [1-(14)C]IAA by segments excised from cress roots. The inhibition by DIHB of ethylene production by this tissue does not, therefore, arise from a reduction of IAA levels. These findings are discussed in relation to the effects of DIHB on cress root growth.
在之前的研究中，3,5-二碘-4-羟基苯甲酸（DIHB）被证明可以促进在光照下生长的荠（Lepidium sativum）幼苗的根伸长，并抑制该组织中生长素诱导的乙烯生成。尽管 DIHB 是辣根过氧化物酶氧化吲哚-3-乙酸（IAA）的辅因子，但它抑制了从荠根切下的片段中[1-（14）C]IAA 的脱羧。因此，DIHB 对该组织中乙烯生成的抑制作用不是由于 IAA 水平的降低引起的。这些发现与 DIHB 对荠根生长的影响有关。
