“…These products appeared to be similar or identical to translation products that were enhanced following in vivo auxin treatment . Two classes of soluble ABP have been reported in cultured soybean cells [8,20] showing some similarities with those described earlier in pea epicotyl tissue [19] . The soybean sites vary both in number and affinity through the cell cycle [8], but whether there is any causal relationship with cell division is not clear .…”

Rapid advances have been made in the study of auxin binding proteins (ABPs) in the last five years . In particular, an ABP in maize membranes has been cloned, sequenced and both monoclonal and polyclonal antibodies to this ABP have been developed . Structural and functional analysis has begun and there is good electrophysiological evidence that ABP in the plasma membrane functions as a receptor, probably involved in auxin-induced cell expansion . The role of the large amount of ABP in the endoplasmic reticulum is less clear, as is the relationship to soluble ABPs . At present there is only some circumstantial evidence relating any ABP to cell division . Receptors for synthetic inhibitors of auxin transport (phytotropins) are also of interest in relation to auxin action, but are less well characterised . Identification of new naturally-occurring phytotropins could lead to novel plant growth regulators .

“…The soybean sites vary both in number and affinity through the cell cycle [8], but whether there is any causal relationship with cell division is not clear . The soluble ABPs from pea are reported to stimulate transcription in isolated pea nuclei in an auxin-dependent manner [20], but no data have been presented.…”

“…To date, the activity of various soluble auxin-binding proteins has been identified as the stimulation of RNA synthesis in isolated nuclei. [21][22][23][24][25] The auxin-binding proteins (ABP-I and ABP-II) purified from etiolated mung bean seedlings 26 -28) stimulate the synthesis of mRNA in isolated nuclei. 23 ) In the presence of ABP-I and ABP-II, IAA has no further effect on transcription, in terms of the overall degree of stimulation.…”
