Artificial top-light is more efficient for tomato production than inter-light
Verheul, Michel; Maessen, Hendricus; Paponov, Martina; Panosyan, Anush; Kechasov, Dmitry; Naseer, Muhammad; Paponov, Ivan (Peer reviewed; Journal article, 2022-09-17)Studies of whole-plant responses of tomato to light environments are limited and cannot be extrapolated from observations of seedlings or short-term crops in growth chambers. Effects of artificial light sources like high ... -
Auxin-Induced Plasma Membrane Depolarization Is Regulated by Auxin Transport and Not by AUXIN BINDING PROTEIN1
Paponov, Ivan; Dindas, Julian; Król, Elżbieta; Friz, Tatyana; Budnyk, Vadym; Teale, William; Paponov, Martina; Hendrich, Rainer; Palme, Klaus (Journal article; Peer reviewed, 2019-01-17)Auxin is a molecule, which controls many aspects of plant development through both transcriptional and non-transcriptional signaling responses. AUXIN BINDING PROTEIN1 (ABP1) is a putative receptor for rapid non-transcriptional ... -
Decoupling of Plant Growth and Accumulation of Biologically Active Compounds in Leaves, Roots, and Root Exudates of Hypericum perforatum L. by the Combination of Jasmonate and Far-Red Lighting
Paponov, Martina; Antonyan, Manya; Slimestad, Rune; Paponov, Ivan (Peer reviewed; Journal article, 2021-08-27)The plant hormone jasmonic acid (JA) fine tunes the growth–defense dilemma by inhibiting plant growth and stimulating the accumulation of secondary compounds. We investigated the interactions between JA and phytochrome B ... -
Differential Regulation of Kernel Set and Potential Kernel Weight by Nitrogen Supply and Carbohydrate Availability in Maize Genotypes Contrasting in Nitrogen Use Efficiency
Paponov, Ivan; Paponov, Martina; Sambo, Paolo; Engels, Christof (Peer reviewed; Journal article, 2020-05-15)Sub-optimal nitrogen (N) conditions reduce maize yield due to a decrease in two sink components: kernel set and potential kernel weight. Both components are established during the lag phase, suggesting that they could ... -
Natural Auxin Does Not Inhibit Brefeldin A Induced PIN1 and PIN2 Internalization in Root Cells
Paponov, Ivan; Friz, Tatyana; Budnyk, Vadym; Teale, William; Wüst, Florian; Paponov, Martina; Al-Babili, Salim; Palme, Klaus (Journal article; Peer reviewed, 2019-05-09)The vesicle trafficking inhibitor Brefeldin A (BFA) changes the localization of plasma membrane localized PINs, proteins that function as polar auxin efflux carriers, by inducing their accumulation within cells. Pretreatment ... -
Nitrogen Deficiency and Synergism between Continuous Light and Root Ammonium Supply Modulate Distinct but Overlapping Patterns of Phytohormone Composition in Xylem Sap of Tomato Plants
Paponov, Martina; Arakelyan, Aleksandr; Dobrev, Petre I.; Verheul, Michel; Paponov, Ivan (Peer reviewed; Journal article, 2021-03-18)Continuous light (CL) or a predominant nitrogen supply as ammonium (NH4+) can induce leaf chlorosis and inhibit plant growth. The similarity in injuries caused by CL and NH4+ suggests involvement of overlapping mechanisms ... -
Organic Waste-Based Fertilizer in Hydroponics Increases Tomato Fruit Size but Reduces Fruit Quality
Kechasov, Dmitry; Verheul, Michel; Paponov, Martina; Panosyan, Anush; Paponov, Ivan (Peer reviewed; Journal article, 2021-06-23)In regions with intensive agricultural production, large amounts of organic waste are produced by livestock animals. Liquid digestate from manure-based biogas production could potentially serve as fertilizer if integrated ... -
Pinpointing regulatory protein phosphatase 2A subunits involved in beneficial symbiosis between plants and microbes
Averkina, Irina Orestovna; Harris, Muhammad; Asare, Edward Ohene; Hourdin, Bérénice; Paponov, Ivan; Lillo, Cathrine (Peer reviewed; Journal article, 2021-04-16)Background PROTEIN PHOSPHATASE 2A (PP2A) expression is crucial for the symbiotic association between plants and various microbes, and knowledge on these symbiotic processes is important for sustainable agriculture. Here ... -
Reduction of geomagnetic field (GMF) to near null magnetic field (NNMF) affects Arabidopsis thaliana root mineral nutrition
Narayana, Ravishankar; Fliegmann, Judith; Paponov, Ivan; Maffei, Massimo (Journal article, 2018)The Earth magnetic field (or geomagnetic field, GMF) is a natural component of our planet and variations of the GMF are perceived by plants with a still uncharacterized magnetoreceptor. The purpose of this work was to ... -
Specific PP2A catalytic subunits are a prerequisite for positive growth effects in arabidopsis co-cultivated with Azospirillum brasilense and pseudomonas simiae
Averkina, Irina Orestovna; Paponov, Ivan; Sanchez-Serrano, Jose J; Lillo, Cathrine (Peer reviewed; Journal article, 2020-12-30)Plant growth-promoting rhizobacteria (PGPR) stimulate plant growth, but the underlying mechanism is poorly understood. In this study, we asked whether PROTEIN PHOSPHATASE 2A (PP2A), a regulatory molecular component of ... -
Supplemental Light-Emitting Diode Inter-Lighting Increases Tomato Fruit Growth Through Enhanced Photosynthetic Light Use Efficiency and Modulated Root Activity
Paponov, Martina; Kechasov, Dmitry; Lacek, Jozef; Verheul, Michel; Paponov, Ivan (Peer reviewed; Journal article, 2020-01-10)We investigated the effect of supplemental LED inter-lighting (80% red, 20% blue; 70 W m−2; light period 04:00–22:00) on the productivity and physiological traits of tomato plants (Flavance F1) grown in an industrial ...
