Plants use light as a resource and signal. Photons within the 400-700 nm waveband are considered photosynthetically active. Far-red photons (FR, 700-800 nm) used by plants to detect nearby vegetation elicit shade avoidance syndrome. In addition, FR have also been shown contribute photosynthesis, but knowledge about these dual effects remains scarce. Here, we study shoot-architectural photosynthetic responses supplemental during photoperiod in several rice varieties. We observed that...
Abstract Rcr3 is a secreted protease of tomato that targeted by fungal effector Avr2, inhibitor the pathogen Cladosporium fulvum . The Avr2-Rcr3 complex recognized receptor-like protein Cf-2, triggering hypersensitive cell death (HR) and disease resistance. Avr2 also targets paralog Pip1, which not required for recognition but contributes to basal Thus, acts as guarded decoy in this interaction, trapping fungus into event. Here we show evolved > 50 million years ago (Mya), whereas Cf-2...
Abstract Natural plant populations are polymorphic and show intraspecific variation in resistance properties against pathogens. The activation of the underlying defence responses can depend on perception pathogen-associated molecular patterns or elicitors. To dissect such variation, we evaluated induced by laminarin (a glucan, representing an elicitor from oomycetes) wild tomato species Solanum chilense correlated this to observed infection frequencies Phytophthora infestans. We measured...
Abstract Secreted immune proteases “Required for Cladosporium resistance-3” (Rcr3) and “Phytophthora-inhibited protease-1” (Pip1) of tomato (Solanum lycopersicum) are both inhibited by Avirulence-2 (Avr2) from the fungal plant pathogen fulvum. However, only Rcr3 acts as a decoy co-receptor that detects Avr2 in presence Cf-2 receptor. Here, we identified crucial residues required Cf-2-mediated signaling bioengineered various to trigger Avr2/Cf-2-dependent immunity. Despite substantial...
Tuberculosis is a devastating disease, taking one human life every 20 seconds globally.
Natural plant populations encounter strong pathogen pressure and defence-associated genes are known to be under selection dependent on the by pathogens. Here, we use of wild tomato Solanum chilense investigate natural resistance against Cladosporium fulvum , a well-known ascomycete domesticated tomatoes. Host used from distinct geographical origins share defined evolutionary history. We show that S. differ in pathogen. Screening for major gene-mediated recognition throughout whole species...
Abstract The wild tomato species Solanum chilense is divided into geographically and genetically distinct populations that show signs of defense gene selection differential phenotypes when challenged with several phytopathogens, including the oomycete causal agent late blight Phytophthora infestans . To better understand phenotypic diversity this disease resistance in S to assess effect plant genotype versus pathogen isolate, respectively, we evaluated infection frequency a systematic...
Abstract Plant pathogens pose a high risk of yield losses and threaten food security. Technological scientific advances have improved our understanding the molecular processes underlying host–pathogen interactions, which paves way for new strategies in crop disease management beyond limits conventional breeding. Cross‐family transfer immune receptor genes is one such strategy that takes advantage common plant signalling pathways to improve resistance crops. Sensing microbe‐ or host...
ABSTRACT Accurately determining the elemental composition of plant tissues is essential for physiological studies on stress, including salinity tolerance. However, high-throughput routine analysis light elements (range sodium to calcium) in samples challenging due need complete sample dissolution and expensive inductively coupled plasma-mass-spectrometry (ICP-MS) analysis. Lower costs method (ion chromatography, ion selective electrodes) exists, but also require lack sensitivity very small...
ABSTRACT Secreted immune proteases Rcr3 and Pip1 of tomato are both inhibited by Avr2 from the fungal plant pathogen Cladosporium fulvum but only act as a decoy co-receptor that detects in presence Cf-2 receptor. Here, we identified crucial residues required for Cf-2-mediated signalling bioengineered various to trigger Avr2/Cf-2 dependent immunity. Despite substantial divergences orthologs eggplant tobacco, minimal alterations were sufficient Avr2/Cf-2-triggered signalling. Tomato Pip1,...

Abstract Natural plant populations encounter strong pathogen pressure and defense-associated genes are known to be under different selection dependent on the by pathogens. Here we use wild tomato Solanum chilense investigate natural resistance against Cladosporium fulvum , a well-known pathogenic fungus of domesticated tomatoes. We show that S. differ in pathogen. Next, explored underlying molecular processes species wide-context. Then, focusing recognition two prominent avirulence factors...
This assay is based on luminol and horseradish peroxidase-dependent chemiluminescence detection of reactive oxygen species (ROS) production in plant leaf discs with some modification to make it suitable for tomato, specifically wild tomato Solanum chilense. We tried non-buffered (Water) buffered systems (MES MOPS) evaluate the robustness detect ROS S. chilense discs. Buffering 20mM MOPS at pH 7.5 during resulted best outputs high reproducibility.

<p>In the present study, effect of ascorbic acid, a known growth adjuvant on encapsulated protocorm-like-bodies (PLBs) <em>Rhynchostylis retusa</em> Bl. was investigated. PLBs were in calcium alginate (3.5% sodium and 100mM chloride) prepared Mitra <em>et al.</em> (1976) basal medium supplemented with different concentration acid (5, 10, 15, 20mM). The stored at 25°C. Their germination response potential evaluated after every 4 weeks media. Control set PLBs,...
