Abstract In Arabidopsis (Arabidopsis thaliana), the blue light photoreceptor phototropins (phot1 and phot2) fine-tune photosynthetic status of plant by controlling several important adaptive processes in response to environmental variations. These include stem petiole phototropism (leaf positioning), leaf flattening, stomatal opening, chloroplast movements. The PHYTOCHROME KINASE SUBSTRATE (PKS) protein family comprises four members (PKS1–PKS4). PKS1 is a novel phot1 signaling element during...
Abstract The introduction of high power LED lighting systems for horticulture has stimulated substantial interest from both the research community and protected industry. have potential to reduce electrical energy consumption compared conventional pressure sodium lights their efficiency continues improve. In addition s carbon footprints running costs, also provides considerable opportunities exploit wealth photobiological knowledge produce horticultural benefits. narrow emission spectra...
We surveyed 24 plant species to examine how leaf anatomy influenced chloroplast movement and the optical properties of leaves change with position. All examined exhibited light-dependent movements but associated changes in absorptance varied considerably magnitude. Chloroplast movement-dependent were greatest shade species, which >10% observed between high- low-light treatments. Using Kubelka-Munk theory, we found that absorption (k) chlorophyll a efficiency (k*) correlated cell diameter,...
Abstract Natural selection on photosynthetic performance is a primary factor determining leaf phenotypes. The complex CO 2 diffusion path from substomatal cavities to the chloroplasts – mesophyll conductance ( g m ) limits rate in many species and hence shapes variation morphology anatomy. Among sclerophyllous succulent taxa, structural investment leaves, measured as dry mass per area LMA ), has been implicated decreased . However, herbaceous taxa with high , it less certain how impacts...
SUMMARY 1. The changes in the vertical distributions of red coloured Planktothrix rubescens and green P. agardhii filaments Blelham Tarn, English Lake District, were related to profiles temperature light attenuation continuous records surface irradiance windspeed, from August 1999 October 2000. 2. potential growth rate each organism was calculated at 0.5 m depths hourly intervals throughout year, using algorithms determined rates culture. analyses indicated that there sufficient for growth,...
• Comparisons were made of the depths where cyanobacterium Planktothrix rubescens stratified in lakes and daily insolation supported neutral buoyancy organism. The percentage filaments floating sinking measured cultures grown under light : dark cycles at different irradiances. Qn, for buoyancy, was determined as that which 50% floating, averaged over 24-h period. For P. 9316 from Lake Zürich, Qn 0.28 mol m−2; during summer period stratification depth (zn) this occurred varied between 5 14 m,...
In cyanobacteria of the genus Planktothrix, there are three length variants gvpC, gene that encodes outer protein gas vesicle. Sequence analyses indicated allelic gvpC differ principally in presence or absence a 99 nt and 213 section. Strains with new variant, 28, which 28 kDa form GvpC, produce vesicles collapse at relatively low critical pressure (p c) 0·61–0·75 MPa. The authors have identified 12 classes gvp genotypes number arrangement alternating gvpA–gvpC genes ΩC, fragment gvpC. was...
Trait heterogeneity in a population increases the likelihood that some individuals will survive an unpredictable environmental stress. Individual plants mature at different rates due to genetics, factors, and random chance. All of this contributes trait heterogeneity. EARLY FLOWERING3 (ELF3), core circadian clock component, determines developmental timing, here we tested hypothesis it would shape We developed model predicting faster-growing populations exhibit greater during development but...
Within plastids, geranylgeranyl diphosphate synthase is a key enzyme in the isoprenoid biosynthetic pathway that catalyzes formation of diphosphate, precursor molecule to several biochemical pathways including those lead into biosynthesis carotenoids and abscisic acid, prenyllipids such as chlorophylls, diterpenes gibberellic acid. •We have identified mutants GERANYLGERANYL DIPHOSPHATE SYNTHASE 1 (GGPS1) gene, which encodes major plastid-localized Arabidopsis thaliana. •Two T-DNA insertion...
• Differences in photosynthetic production and conversion to biomass of the red-coloured cyanobacterium Planktothrix rubescens green-coloured agardhii , were investigated relation their growth Blelham Tarn, UK, using clonal isolates from lake. Growth rates (µ) measured cultures under 12 h : light dark cycles at 15 irradiances ( E ) temperatures (Θ) 10–25°C. Photosynthetic P same conditions. For P. µ reached a maximum 0.33 d −1 25°C photon > 40 µmol m −2 s exceeded for over range Tarn (<...
Species of Oscillatoria with abundant gas vesicles have been reclassified in the genus Planktothrix and names species distinguished partly by differences pigmentation filament width retained new combinations. We determined variation (d f ) vesicle critical pressure (P c three collections spp.: 56 green coloured isolates (P. agardhii) 32 red rubescens) from Blelham Tarn, a shallow lake English Lake District; 19 P. rubescens Zurich, deep Switzerland; 25 15 21 Nordic lakes NIVA collection.

Abstract Critical editions, translations, and scholarly discussions typically treat Luke 20,18 as a separate logion from the preceding quotation Ps 118 (MT; LXX 117) in 20,17 that ends Jesus’ telling of parable wicked tenants. Despite its separation quote, scholars have seen line allusions to Isa 8,14–15 Dan 2,34–35.44–45. This article questions both these usual assumptions, arguing (a) should fact be read second half begun (b) language crushing particular “winnowing” (λικμάω) takes up...
As part of NTT JTSR's series on Key Texts, the present article discusses Mark Goodacre's influential work, The Case Against Q. book challenges standard solution to synoptic problem, two-document hypothesis, arguing against existence Q and for Luke's use Matthew. This takes a critical look back at book's main arguments examines impact it has had subsequent scholarship.
