Quantitative proteomic analysis to capture the role of heat-accumulated proteins in moss plant acquired thermotolerance

ABSTRACT: At dawn of a scorching summer day, land plants must anticipate upcoming extreme midday temperatures by timely establishing molecular defenses that can maintain heat-labile membranes and proteins in a functional state. A gradual morning pre-exposure to increasing sub-damaging temperatures induces the accumulation of heat-shock proteins (HSPs) that are central to the onset of plant acquired thermotolerance (AT). In an attempt to gain knowledge on the mechanisms of AT in the model land plant Physcomitrium patens, we used label-free LC-MS/MS proteomics to quantify the accumulated and depleted proteins before and following a mild heat-priming treatment.

At dawn of a scorching summer day, land plants must anticipate upcoming extreme midday temperatures by timely establishing molecular defences that can keep heat-labile membranes and proteins functional.

Project description:Serine proteases has been vastly reported to be found (and identified) only in seed extracts of Canavalia ensiformis (C. ensiformis), however, our group observed expressive serine protease activities in aqueous extracts from leaves, seeds, roots, and stem, especially in a leaf extract obtained with distillated water (CE-A). Additionally, this extract demonstrated very good stability in high temperatures and in the presence of chemical agents. In order to study the serine protease activity in leaves, CE-A was submitted to benzamidine-sepharose affinity column and an enriched fraction of serine proteases, named CE-ABza was purified 1.65 fold, yielding a total recovery of about 62%. Based upon zymographic analysis in a gelatin-SDS-PAGE-, the CE-ABza fraction presented an enzymatic activity band at approximately 90 kDa molecular mass region under non-reducing conditions and three bands at 17, 32 and also at 90 kDa under reducing condition. This fraction was able to hydrolyze, in a different way, peptidomimetic and protein substrates. The maximal activity was observed at basic pH values (8.0 to 9.5) and temperature about 40°C. These enzymes exhibited important thermal stability and were significantly inhibited by serine protease inhibitors, such as benzamidine and TPCK. Calcium, magnesium, manganese and zinc ions had a negative modulation on the CE-ABza activity. Mass spectrometry-based proteomics approach identified showed homology with 11 plant proteases from different legumes species, indicating their presence or demonstrating that CE-Bza proteases share specific region of the primary structure of theses enzyme, although the C. ensiformis genome and protein databases are yet to be publicly available. These results demonstrated that these molecules found in both the CE-A extract and the CE-ABza fraction presented important properties that could be used as potential pharmacological and biotechnological targets as therapeutic option. Besides, identification and characterization of C. ensiformis proteases contribute to the studies of plant enzymes.

Project description:Analysis of transcriptome in moss Physcomitrella patens CNGCb null mutant at 25 and 34 degrees C for 30 minutes. Results provide insight into role of CNGCb in acquired thermotolerance induced by non-lethal heat treatment. Typically at dawn of a hot summer day, land plants need precise molecular thermometers to sense harmless increments in the ambient temperature to timely develop a heat-shock response (HSR) and accumulate protective heat shock proteins (Hsps), in anticipation of upcoming harmful temperatures at mid-day. Here, we found that the CNGCb gene from Physcomitrella patens and its Arabidopsis ortholog CNGC2, encode for a component of cyclic nucleotide gated Ca2+ channels acting as the primary thermosensors of land plant cells. Disruption of CNGCb or CNGC2 produced a hyper-thermosensitive phenotype, giving rise to a HSR and acquired thermotolerance at significantly milder heat-priming treatments than in wild type plants. In an aequorin-expressing moss, CNGCb loss-of-function caused altered Ca2+ signaling and a sustained Ca2+ influx. Patch clamp recordings on moss protoplasts showed the presence of three distinct thermo-responsive Ca2+-channels in wild type cells. Deletion of CNGCb led to a total absence of one, and it increased the open probability of the remaining two thermo-responsive Ca2+ channels. Thus, both in Arabidopsis and moss, CNGC2 and CNGCb are expected to form with other related CNGCs, heteromeric Ca2+ channels in the plasma membrane that respond to mild increments in the ambient temperature by triggering an optimal HSR, leading to the onset of plant acquired thermotolerance. The WT moss tissues were heat-shocked for a half an hour at 34°C and 38°C and CNGCb at 25and 34°C followed by liquid nitrogen freezing. Total RNA was isolated using RNeasy Mini Kit (QIAGEN, Hilden, Germany) and two biological replicate samples for each treatment, were extracted. An Agilent-certified microarray service lab (MOgene, LC, St. Louis, MO, USA) was used to verify the integrity of the RNA and perform the microarray experiments. Two biological replicates were performed.
