Polyhydroxyalkanoates (PHAs) make a large class of biodegradable biopolymers that are naturally synthesized by numerous microorganisms. These could be an alternative to commonly used plastics based on petroleum. Production PHAs in bioreactors using microorganisms is not widely applied due its unprofitability. Using transgenic plants for this purpose may cheaper and more environmental friendly because the biosynthesis only water, mineral salts, CO2 light. Additionally, capable degrading as...
The EGY3 is a pseudoprotease, located in the thylakoid membrane, that shares homology with family of site-2-proteases (S2P). Although S2P proteases are present cells all living organisms, was found only plant cells. sequence pseudoprotease highly conserved kingdom; however, little known about its physiological importance. Results obtained real-time PCR indicated expression gene dramatically induced during first few hours exposure to high light and high-temperature stress. observed increase...
In this study, we investigated the importance of one intramembrane proteases, EGY2, for proper functioning PSII under short-term high light stress conditions. EGY2 is a chloroplast protease S2P family, whose absence in Arabidopsis thaliana affects protein composition. The egy2 mutants exhibited slower degradation PsbA and decreased content PsbC PsbD. During exposure to stress, these stoichiometric changes affect functional state PSII, leading its higher sensitivity photoinhibition reaction...
Plants adjust their architecture to a constantly changing environment, requiring adaptation of differential growth. Despite importance, molecular switches, which define growth transitions, are largely unknown. Apical hook development in dark grown Arabidopsis thaliana (A. thaliana) seedlings serves as suitable model for transition plants. Here, we show that the phytohormone auxin counteracts light-induced during apical opening. We, subsequently, identified genes inversely regulated by light...
It is known that cells contain various uncommon nucleotides such as dinucleoside polyphosphates (NpnN's) and adenosine 5'-phosphoramidate (NH2-pA) belonging to nucleoside 5'-phosphoramidates (NH2-pNs). Their cellular levels are enzymatically controlled. Some of them accumulated in under stress, therefore, they could act signal molecules. Our previous research carried out Arabidopsis thaliana grape (Vitis vinifera) showed NpnN's induced the expression genes phenylpropanoid pathway favored...
EGY1 (ethylene-dependent gravitropism-deficient and yellow-green 1) is an intramembrane metalloprotease located in chloroplasts, involved many diverse processes including chloroplast development, chlorophyll biosynthesis, the ethylene-dependent gravitropic response. Plants deprived of this protease display pleiotropic effects such as early senescence phenotype a poorly developed thylakoid system membrane mature chloroplasts. We applied GC/MS technique to analyze changes fatty acid...
Summary Dinucleoside polyphosphates (Np n Ns) are considered novel signalling molecules involved in the induction of plant defence mechanisms. However, Np Ns signal recognition and transduction still enigmatic. Here we report, for first time, that diadenosine tetraphosphate (Ap 4 A) is recognized by Arabidopsis thaliana purinoreceptor P2K1/DORN1 (Does Not Respond to Nucleotides 1) causes stomatal closure. Extracellular Ap A- dicytidine (Cp C)-induced closure was observed using a microscope....
Dinucleoside polyphosphates (NpnNs) are considered novel signalling molecules involved in the induction of plant defence mechanisms. However, NpnN signal recognition and transduction still enigmatic. Therefore, aim our research was identification receptor pathways evoked by these nucleotides. Earlier, we proved that purine pyrimidine NpnNs differentially affect phenylpropanoid pathway Vitis vinifera suspension-cultured cells. Here, report, for first time, both diadenosine tetraphosphate...
