One of the most important functions of blue light (BL) is to induce chloroplast movements in order to reduce the damage to the photosynthetic machinery under excess light. Hydrogen peroxide (H(2)O(2)), which is commonly generated under various environmental stimuli, can act as a signalling molecule that regulates a number of developmental processes and(More)
Heat shock transcription factor A2 (HsfA2) participates in multiple stress responses. To provide new insights into the role of HsfA2 in the heat stress (HS) response, in vivo production and localization of reactive oxygen species (ROS) and mitochondrial dynamics were investigated during the onset of cell death induced by an HS (40 degrees C, 10 min) applied(More)
Methyl jasmonate (MeJa) is a well-known plant stress hormone. Upon exposure to stress, MeJa is produced and causes activation of programmed cell death (PCD) and defense mechanisms in plants. However, the early events and the signaling mechanisms of MeJa-induced cell death have yet to be fully elucidated. To obtain some insights into the early events of this(More)
In this paper, a new principle biosensor for non-invasive monitoring of the regulation of photosynthetic metabolism based on quantitative measurement of delayed fluorescence (DF) is developed. The biosensor, which uses light-emitting diode lattice as excitation light source and a compact Single Photon Counting Module to collect DF signal, is portable and(More)
We will study the upper semicontinuity of pullback attractors for the 3D nonautonomouss Benjamin-Bona-Mahony equations with external force perturbation terms. Under some regular assumptions, we can prove the pullback attractors A(ε)(t) of equation, u(t)-Δu(t)-νΔu+∇·(-->)F(u)=εg(x,t), x ∈ Ω, converge to the global attractor A of the above-mentioned equation(More)
