Intensity of light water equation5/1/2024 ![]() In the past two decades, computational approaches have been used extensively to investigate the dynamic behavior of regulatory networks related to photosynthesis. In tomato production facilities, decreased light transmittance leads to decreased light intensity, which will further affect photosynthesis, thus influencing the growth and development of tomato plants. Recent efforts aimed at controlling light intensity by setting diverse shade amounts and calculating light transmittances to explore photosynthetic characteristics and results suggested that increasing light transmittance enhanced the photosynthetic rate. In order to identify the effect of light intensity on photosynthesis, experimental attempts have been conducted to control light density by managing shade avoidance. Weak light limits the abundances of gene products and photosynthesis, and the absence of Lhcb1 led to a marked reduction in production in a field experiment. Transduction from chloroplast to nucleus facilitates the highly coordinated expression of the many photosynthetic genes between these different compartments. Well-defined relationships among pigment perception and interception of light, electron transport systems, light reaction, and the carboxylation or oxygenation reactions of photosynthesis have been reported. Light intensity is the driving force enabling the plant to achieve a balance to conserve energy towards improvement of photosynthesis. As the amount of light increases, higher intensity under optimum growth conditions enhances the rate of photosynthesis in tomato. Under low light intensity, photosynthesis is limited due to the low rates of the light-dependent reaction. In tomato, light intensity is an important environmental cue to conserve energy towards improvement of photosynthesis. Tomato ( Solanum lycopersicum L.) is one of the main vegetable crops cultivated worldwide, and prefers strong light in the photosynthetic process. Our study reveals a potential mechanism underlying the circadian regulation of photosynthesis by the clock under different light intensities in tomato. When exposed to low light intensity, the peak times of clock and photosynthetic genes were shifted backward by 1–2 hours, the period was elongated by approximately the same length, and the photosynthetic parameters attained low values and showed delayed peak times, which confirmed our model predictions. Further simulation validated the dynamic behaviors of the circadian clock and photosynthetic outputs under low (62.5 μmol m −2 s −1) and normal (187.5 μmol m −2 s −1) intensities. The model recapitulates the expression pattern of the core oscillator under moderate light intensity (100 μmol m −2 s −1). The model parameters were determined by minimizing the cost function ( ), which is defined by the errors of expression levels, periods, and phases of the clock genes ( CCA1, PRR9, TOC1, ELF4, GI, and RVE8). Here, we propose a first computational model for circadian-clock-controlled photosynthesis, which consists of the light-sensitive protein P, the core oscillator, photosynthetic genes, and parameters involved in the process of photosynthesis. Although the interaction between photosynthesis and the circadian clock has been confirmed, the mechanism of how light intensity affects photosynthesis through the circadian clock remains unclear. The diver is unable to work without artificial light if the light intensity falls to 20% of the intensity at the surface.Photosynthesis is involved in the essential process of transforming light energy into chemical energy. How deep can the diver go without artificial light? The diver is unable to work without artificial light if the light intensity falls to 20% of the intensity at the surface. Show that the differential equation has a solution of the form L(x) = Ae^(-Kx), and determine the constant A.Ī diver knows from experience that in a Norwegian fjord, the light intensity is halved at 4 meters deep. Set the light intensity at the surface to 1, i.e. Where x is the depth below the water surface measured in meters. The light intensity under water can be described by the differential equation:
