“…Therefore, our data rather indicate an auxin triggered post‐transcriptional activation/inactivation event on pPLA‐I to be evoked in less than 10 min.

“…The ppla‐I and abp1 mutants identify a function at the intersection of auxin and light signalling. There is overall similarity of phenotypes of the abp1/ABP1 and abp1–5 mutant and the ppla‐I mutants, which consist of the similar regulatory defects in auxin‐dependent responses like gene regulation, phototropism and gravitropism (Effendi & Scherer ; Effendi et al . , ).…”

“…In contrast, from experimental findings a new mechanism of polarity perception has recently emerged, in which auxin is perceived locally in the cell wall through ABP1‐receptors (Xu et al ; Effendi and Scherer ; Shi and Yang ; Craddock et al ). This receptor and its associated partners subsequently stimulate the activation of cell polarity constituents, the ROPs.…”

In the past 20-30 years, developmental biologists have made tremendous progress in identifying genes required for the specification of individual cell types of an organ and in describing how they interact in genetic networks. In comparison, very little is known about the mechanisms that regulate tissue polarity and overall organ patterning. Gynoecia and fruits from members of the Brassicaceae family of flowering plants provide excellent model systems to study organ patterning and tissue specification because they become partitioned into distinct domains whose formation is determined by polarity establishment both at a cellular and whole tissue level. Interactions among key regulators of Arabidopsis gynoecium and fruit development have revealed a network of upstream transcription factor activities required for such tissue differentiation. Regulation of the plant hormone auxin is emerging as both an immediate downstream output and input of these activities, and here we aim to provide an overview of the current knowledge regarding the link between auxin and female reproductive development in plants. In this review, we will also demonstrate how available data can be exploited in a mathematical modeling approach to reveal and understand the feedback regulatory circuits that underpin the polarity establishment, necessary to guide auxin flows.

“…Membrane vesicles carrying PIN proteins undergo dynamic recycling to and from the PM and auxin regulates its own transport by inhibiting the endocytic step of this recycling [34][35][36]. It is believed that ABP1 mediates the effect of auxin on endocytosis and that ABP1 can control the clathrin-mediated internalization of PIN proteins, which regulate the amount and dynamics of PIN auxin efflux carriers at the PM [37][38][39][40][41]. It is likely that ABP1 has an influence on cell expansion and division through being involved in the regulation of polar auxin transport, which affects leaf growth and vascular patterning in ramie.…”

Plant transformation and growthA ramie cultivar "Xiangzhu 3" was used as transformation material. *Corresponding author:Xuewen Zhang, College of Bioscience and Biotechnology, Hunan Agricultural University, Changsha 410128, China, Tel: 86-731-84618060, 84618784; E-mail: lihua3000@gmail.com AbstractAUXIN BINDING PROTEIN1 (ABP1) has long been proposed as a candidate of auxin receptor to mediate auxin action in plants. It is essential for plant organ development. The function of ABP1 in the development of ramie (Boehmeria nivea L.) remains unclear. Here, we examined the role of the ABP1 gene in the development of shoot in ramie, especially in leaf venation ontogeny, by transforming ABP1 antisense construct into the plants. We showed that ABP1 expression was decreased in ABP1 antisense transgenic plantlets. The decrease of ABP1 expression led to defects in plant growth including dwarf plant, and decreased apical dominance in the intact plant. In addition, ABP1 antisense lines exhibited a serious retard of leaf development involving small and twisted leaves, sparse trichome, and a decreased cell expansion. Moreover, the decreased ABP1 expression repressed the development of leaf venation. ABP1 antisense lines developed an incomplete leaf venation, which became smaller and lacked in some leaf tissues. Though the cell arrangement was normal in midrib and lateral vein, cell size was decrease and some cell layers were missing in midrib. The abnormal phenotype of leaf venation was attributed to the decreases in cell number and size. Our data support that ABP1 is necessary for shoot growth in ramie. More importantly, it plays a key role for the development of ramie leaf venation by regulating both cell expansion and division.
