The role of active oxygen species in plant resistance
Active oxygen species (ROs) play an important role in plant disease resistance. Plants have a complex set of defense mechanisms to resist diseases. When a plant is invaded by a pathogen, its pattern recognition receptor can sense the invasion of the pathogen and trigger the host's immune response, such as an active oxygen outbreak. For example, the protein ZmWAKL, which was the gene for disease resistance, could quickly respond to the invasion of pathogenic bacteria. Through a series of transmissions, it would transmit the phosphorous signal, which would eventually trigger an active oxygen outbreak and trigger a disease resistance response. From the perspective of the plant immune system, the cell surface immune receptor can detect the pathogen related markers and initiate a cell response to resist infection. The activation of the cellular immunity in plant immunity is usually considered a more powerful response, which is related to local cell death and thus limits the spread of infection, and the active oxygen plays a role in this immune response. In addition, the expression of the newly discovered plant immune positive regulation protein LcPIP1 could induce tobacco cell death, the burst of active oxygen, the accumulation of callose, etc., and up-regulate the expression of the Salicolic and Jasmonic acid signaling pathway genes to positively regulate plant resistance to pathogenic bacteria. At the same time, in the normal metabolism of plants, active oxygen was a natural by-product, which played an important role in cell signal transmission and internal balance. However, during periods of environmental stress (such as invasion of a pathogen), the level of ROS1 will increase sharply, which in turn will affect the cell structure to resist the disease.

Green plant species in the road green belt
Common green plant species in the road green belt include eugenia, Photinia glabra, small dragon cypress, yellow bean boxwood, hibiscus, golden banyan, podocarpus, privet, cypress, etc. These green plants appeared in different areas. They could green the environment, purify the air, and decorate the road landscape. When choosing plants for road greenery, one needed to consider the climate and soil conditions of the area, as well as the growth characteristics and aesthetic effects of the plants. Different types of green plants were suitable for different places to grow, but there were also some types that were suitable for multiple places to grow. In general, the selection of green plant species in the road green belt should be scientific and reasonable, and the selection should be based on the actual situation to achieve the purpose of beautification of the environment and improvement of air quality.
A bamboo species suitable for the cold resistance in the north
The bamboo species suitable for the cold resistance in the north were bamboo, golden bamboo, black bamboo, green bamboo, early garden bamboo, golden jade bamboo, yellow groove bamboo, purple bamboo, golden bamboo, red bamboo, giant bamboo, etc. These bamboo species had strong cold resistance and could grow and reproduce in the cold environment of the northern region. Among them, gold-inlaid jade bamboo, early garden bamboo, purple bamboo and other varieties were planted in a large area in the northern region and were widely used. These bamboo species not only had cold resistance, but also had ornamental value, which could provide beautiful landscapes for the northern region's landscape.

Evergreen aquatic plant with cold resistance all year round
Cold-resistant evergreen aquatic plants include reed, calamus, canna, water bamboo, umbrella, sand cane and so on. These plants were adapted to cold climates, could maintain green leaves all year round, and could grow in aquatic environments. Among them, reeds were a widely distributed aquatic plant, commonly found in rivers, lakes, ponds, ditches, coastal areas, and low-lying wet lands. They had the ability to purify sewage. Acorus calamus preferred a warm growing environment. It was cold-resistant but avoided drought. The suitable growth temperature was 20-25 ° C. Canna was a commonly used ornamental plant in the subtropics and tropics. It liked warm and sufficient sunlight and was not cold-resistant. These cold-resistant evergreen aquatic plants could grow under different climate conditions and had certain ornamental and environmental purification value.
Is the bowl of lotus for oxygen or oxygen consumption?
The bowl lotus had the effect of increasing oxygen, but it also consumed oxygen. The oxygen produced by the metabolism of the root of the bowl lotus could increase the oxygen content of the water, which was the performance of its oxygen enhancement. At the same time, the bowl lotus was a kind of aquatic organism that consumed more oxygen. Its oxygen demand changed in different growth stages. The oxygen consumption was relatively low in the sprouting stage and the early stage of growth. However, as the growth entered the hyphal formation stage and the rapid growth stage, the oxygen consumption would increase sharply.

Which plant species appeared in large numbers during the Cambrian-era explosion of life?
The Cambrian-era explosion of life was an important event in Earth's history that occurred about 25.1 billion years ago. During this event, many new plant groups appeared on Earth, some of which became the ancestors of modern plants. During the Cambrian-era explosion of life, a large number of trilobites appeared. They were one of the earliest forms of life on Earth. Trilobites had three leaf-like bodies, so they were called "three-leaf plants" in biology. These plant groups played an important role in the early Cambrian-era life, laying the foundation for later evolutionary development. In addition, a large number of bacteria appeared during the Cambrian-era explosion. These microorganisms play an important role in all aspects of life, including photosynthesis and oxygen circulation. During the Cambrian-era explosion of life, a large number of new plant groups appeared, laying the foundation for the development of modern plants.
