We analyzed auxin-induced and ethylene-enhanced elongation of petiole segments in Ranunculus sceleratus L. The early time course of elongation in petiolar segments was monitored with a computer-based video digitizer system. The application of ethylen

If ethics is based on a view of the evolving cosmos, the value of biodiversity becomes more obvious than within any anthropocentric contract ethics. Conservation is not enough. Diversity, the manifold of genetic elements, polymorphisms and their comi

Dear Editor, I was astonished to read how Baluska and colleagues et al. (see [Robinson et al., 2018][1]) interpret the plant membrane vesicles we characterized 3 decades ago ([Hertel et al., 1983][2]; [Hertel, 1987][3]). These vesicles were extracted

Alkylation of Reissert compounds derived from 3-methylisoquinolines with several 2-cyanobenzylbromides followed by hydrolytic cleavage provided the corresponding 1-benzyl-3-methylisoquinolines. Treatment of the latter with methylmagnesiumiodide cause

Endogenous extractable factors associated with auxin action in plant tissues were investigated, especially their effects on elongation of 1-mm coleoptile segments of maize (Zea mays L.), in the presence of saturating 10 microM indole-3-acetic acid (I

Microsomal membrane vesicles and purified plasma membranevesicles obtained from coleoptiles of maize (Zea mays L.) weresubjected to pH shifts from pH 7.8 to 4.7. In the presence of ATPaseinhibitors such as vanadate, net accumulation of radiolabelled

—Phototaxis of the flagellate Euglena gracilis has been thought to be mediated by flavin photoreceptor molecules localized in the paraflagellar body (PFB). From isolated flagella of Euglena a riboflavin (RF)-binding protein was solubilized and puri

Te photoreceptor for phototaxis in Euglena gracilis is thought to be localized at the base of the major flagellum. Flagella were isolated from Euglena gracilis and from the closely related Astasia longa . In the case of Euglena the paraflagellar body

Binding of 1-naphthylacetic acid (1-NAA) was assayed in microsomal membranes from Zea mays coleoptiles and from hypocotyls of Cucurbita pepo. Auxin binding site II was differentiated from site I binding by using phenylacetic acid (PAA) to saturate si

Jose Antonio Campos-Ortega (1940-2004), a Spanish scientist who became a leading figure in the developmental genetics of the nervous system, spent most of his scientific life in Germany. Nevertheless, he remained deeply rooted in his native country.
