“…All of the deduced amino acid ABP1 sequences possess a leader peptide at the N-terminus of the protein and a KDEL (Lys-Asp-Glu-Leu) motif at the C-terminus. These features are characteristic of endoplasmic reticulum resident proteins, which is consistent with the biochemical characterization of the ABP1 protein in maize (Zm-ERabp1) [4,5,16]. However, by using polyclonal antibodies to Zm-ERabp1, Diekmann and coworkers [17] have visualized the protein at the surface of maize protoplasts suggesting that a fraction of the protein could escape the ER and reach the plasma membrane.…”

“…Their functional role in auxin signaling is still unclear and even the function of the most studied auxin-binding protein, ABP1, which is the best candidate for an auxin receptor, remains uncertain. ABP1 is a soluble protein ¢rst isolated from maize coleoptiles [5,6]. Genomic or cDNA clones of ABP1 have been isolated from di¡erent plant species such as maize [6^8], Arabidopsis [9,10], tobacco [11,12], strawberry [13], red pepper [14] or apple tree [15].…”

Hyperpolarization of tobacco protoplasts is amongst the earliest auxin responses described. It has been proposed that the auxin-binding protein, ABP1, or a related protein could be involved in the first step of auxin perception at the plasma membrane. Using for the first time homologous conditions for interaction between the protein Nt-ERabp1 or a synthetic peptide corresponding to the C-terminus and tobacco protoplasts, we have demonstrated that both can induce the hyperpolarization response. The results show that Nt-ERabp1 or the C-terminal peptide alone activates the auxin pathway from the outer face of the plasma membrane.z 1999 Federation of European Biochemical Societies.

Drug delivery technology is emerging as an interdisciplinary science aimed at improving human health. The controlled delivery of pharmacologically active agents to the specific site of action at the therapeutically optimal rate and dose regimen has been a major goal in designing drug delivery systems. Over the past few decades, there has been considerable interest in developing biodegradable drug carriers as effective drug delivery systems. Polymeric materials from natural sources play an important role in controlled release of drug at a particular site. Polyhydroxyalkanoates, due to their origin from natural sources, are given attention as candidates for drug delivery materials. Biodegradable and biocompatible polyhydroxyalkanoates are linear polyesters produced by microorganisms under unbalanced growth conditions, which have emerged as potential polymers for use as biomedical materials for drug delivery due to their unique physiochemical and mechanical properties. This review summarizes many of the key findings in the applications of polyhydroxyalkanoates and polyhydroxyalkanoate nanoparticles for drug delivery system.

“…In particular, wounding of barley plants does not result in JA biosynthesis and a concomitant gene expression (Wasternack, personal communication). Moreover, for barley di¡erent JA-signaling pathways have been proposed, since exogenously applied JA and levels of endogenously formed JA led to the expression of di¡erent genes possibly due to independent perception sites [18,19]. The data presented here suggest that following application of JA jasmonates accumulate extracellularly in tomato, but intracellularly in barley, accompanied in both plants by a complete JA signaling as indicated by the expression of respective marker genes.…”

Jasmonic acid (JA) and its derivatives are well-characterized signaling molecules in plant defense and development, but the site of their localization within plant tissue is entirely unknown. To address the question whether applied JA accumulates extracellularly or intracellularly, leaves of tomato and barley were fed with 14 C-labeled JA and the label was localized in cryo¢xed and lyophilized leaf tissues by microautoradiography. In tomato the radioactivity was detectable within the apoplast, but no label was found within the mesophyll cells. By contrast, in barley leaf tissues, radioactivity was detected within the mesophyll cells suggesting a cellular uptake of exogenously applied JA. JA, applied to leaves of both plants as in the labeling experiments, led in all leaf cells to the expression of JAinducible genes indicating that the perception is completed by JA signal transduction.
