Characterisation of mutants involved in Phytochrome A nuclear import and signal transduction
… was performed using a transgenic line expressing phyA: GFP fusion protein. Aim of the screen was to isolate and characterise Phytochrome A (phyA) nuclear transport mutants. The screening was performed in two steps. First, the mutagenised seedlings were selected on the basis of differences in …

Characterization of eid3 and the putative rei mutants : new insights on Phytochrome A signaling
… highly specific components of phytochrome A (PhyA) signaling, a new screening program (SP) was performed. This SP consists of repetitive pulse treatment of 20 minutes red light followed by 20 minutes far-red light. This multiple pulse program was applied to isolate mutants which were either …

Analysis of phytochrome signaling pathways in Zea mays
… contains five members of the phytochrome family, phyA-phyE. In contrast, genomes of monocots sequenced so far contain only three members, phyA-phyC, although polyploids may have multiple homeologs of each. Studies in Arabidopsis have shown that phytochromes primarily transduce light signals via …

The Mirror Project: A Portrait of Urban Inequality
Photography has historically played a vital role in highlighting urban inequality, as seen in the work of Jacob Riis documenting late 19th-century New York City. Today, amidst ongoing gentrification, traditional mapping methods often fall short in capturing the lived experiences of communities. To …

Zur Regulation und Expression von Aquaporinen unter Berücksichtigung des pflanzlichen Wasserhaushaltes
… Unterschiede bei der Phytochrom-Mutante phyA-103, der Abscisinsäure-Mutante aba3-2 und der Auxin-resistenten Mutante axr1-3. Ferner zeigte die Mutante npq1-2 nicht die beschriebene Abweichung der stomatären Antwort auf Blaulicht. - Die Expressionsmuster eines PIP1b-GFP-Reportergens in …

STRUCTURE-FUNCTION STUDIES OF MULTIPLE INOSITOL POLYPHOSPHATE PHOSPHATASES FROM GUT COMMENSAL BACTERIA
… mutagenizing its active site to mimic that of PhyA, a specific 3- phytase from Aspergillus niger. Further experiments introduced active site residues from human Minpp. The results of these studies reveal that by altering key active site residues, the positional specificity and the ratios of the …

A physiological and genetic analysis of the role of phytochrome in photoperiodic induction of flowering in Arabidopsis Thaliana
… the photobiological input. It also proposes that phyA or C and the blue light photoreceptor promote flowering whereas phyB promotes vegetative development. Two screens were set up to isolate novel photoperiodic mutants. Six mutants were isolated, from ethtylmethane sulphonate mutated seed, which …

Understanding angiosperm genome interactions and evolution: insights from sacred lotus (Nelumbo nucifera) and the carrot family (Apiaceae)
… psbM–psbD and psbA–trnH and the nuclear gene PHYA were sequenced. To these sequence data four RGCs were added, as were previously available data from the nrDNA internal transcribed spacer (ITS) region. These molecular data were analyzed separately and in various combinations using maximum …
