The contents of leaf chlorophyll a and b, the ratio of chlorophyll a/b and the content of chlorophyll a+b in rice leaf are four important factors that determine the photosynthetic function of rice leaf. It is important to clarify the genetic regularity of rice photosynthetic function through the chlorophyll detector. significance. It implies that the molecular genetic mechanism of chlorophyll content is complex, and using different groups to analyze its molecular genetic basis will provide new opportunities and information for rice breeding.
Chlorophyll-a is the main component of the reaction center complex, in which the reaction center in a special state, chlorophyll-a molecules are the photosynthetic pigments that perform energy transformation, and chlorophyll-b is an important part of the light-harvesting pigment-protein complex, and its role is to capture And pass light energy. Both chlorophyll a and chlorophyll b are part of the photosynthetic membrane, and the chlorophyll a/b ratio is generally around 3.
Rice is a C3 plant with strong photorespiration and low photosynthetic rate. The determination of the content of chlorophyll by the chlorophyll detector is the material basis of photosynthesis in rice. Therefore, improving the chlorophyll content in rice leaves can increase the photosynthetic rate, which in turn can increase the yield and improve rice quality. In recent years, studies on chlorophyll-related traits have been increasingly studied. Pay attention.
Chlorophyll is the main pigment for plants to absorb, transmit, and convert light energy. Within a certain range, there is a positive correlation between leaf chlorophyll content and photosynthetic rate. Chlorophyll is divided into two types, a and b, due to different structure and light energy conversion characteristics. Chlorophyll a is good for absorption of long wavelength light, and chlorophyll b is good for absorbing short wavelength light. Chlorophyll a / b ratio and chlorophyll detector for the determination of the British Department of the larger.
