“…It is assumed that ATHB8 has different functions during each of these stages (Baima et al 2001; Donner et al 2010; Ramachandran et al 2017). During the preprocambial stage, its activity probably relates to vascular pattern formation, whereas during the procambial stage, it may be involved in the regulation of meristematic cell divisions and early xylem specification, acting simultaneously as a negative regulator of xylem differentiation (Baima et al 2001; Scarpella et al 2004; Prigge et al 2005; Donner et al 2009; Ramachandran et al 2017).…”

“…Evidences suggest that MP induces not only PIN1 but also ATHB8 gene expressions (Mattsson et al 2003; Donner et al 2009, 2010; Campbell and Turner 2017). It has been shown, for example, that the MP gene can bind directly to the ATHB8 promoter in the region of the TGTCTG sequence, which is very similar to the AuxRE (Donner et al 2009, 2010).…”

The vascular system develops in response to auxin flow as continuous strands of conducting tissues arranged in regular spatial patterns. However, a mechanism governing their regular and repetitive formation remains to be fully elucidated. A model system for studying the vascular pattern formation is the process of leaf vascularization in Arabidopsis. In this paper, we present current knowledge of important factors and their interactions in this process. Additionally, we propose the sequence of events leading to the emergence of continuous vascular strands and point to significant problems that need to be resolved in the future to gain a better understanding of the regulation of the vascular pattern development.

“…30 Alternatively, auxin itself, channeled into narrowing lines of cells with elevated auxin concentrations, could be this co-factor. In this case, one would expect that MP protein is activated (i.e., not repressed by Aux/IAA proteins) only in this subset of its expression domain.…”

“…The pattern and ontogeny of leaf venation are precisely regulated by a variety of substances [9,10]. Auxin has been implicated in controlling all stages of vascular strand formation [11][12][13][14][15]. Auxin distribution and transportation were visualized in Arabidopsis leaf vascular development by using expression analysis of auxin carrier gene PINs and the synthetic auxin responsive promoter DR5 [11][12]15].…”

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.
