Phospholipase D gene for promoting plant root development and application thereof

Abstract

The invention belongs to the technical field of biology, particularly relates to a phospholipase D gene PeuPLD zeta 4 for promoting plant root development and an expression vector, cell line and host bacteria thereof, and particularly discloses application of the gene PeuPLD zeta 4 to breeding of transgenic plants, and the plants include dicotyledonous plants and monocotyledonous plants. The populus euphratica PeuPLD zeta 4 gene separated by the invention is phospholipase D capable of acting on cell membranes and cell nucleuses. The populus euphratica PeuPLD zeta 4 gene is over-expressed in the monocotyledonous plants and the dicotyledonous plants, and thus, the development of plant roots of the monocotyledonous plants and the development of plant roots of the dicotyledonous plants are both remarkably enhanced, and the utilization efficiency of the dicotyledonous plants and monocotyledonous plants to low-water-level underground water is also further improved, thereby enhancing the tolerance of the dicotyledonous plants and monocotyledonous plants to abiotic stress such as high salt and drought. The discovery of the gene has important theoretical and practical significance for culturing excellent crop varieties, especially drought-resistant and salt-resistant crop varieties, and promoting breeding of plants in deserts and arid regions.

AI Technical Summary

Benefits of technology

This patented technology allows scientists to study how certain genes can be used to improve crops' ability to resist damage from environmental factors like dryness or excessive rainwater during periods of abnormal weather conditions called salinity (salt). These genes are found naturally occurring within cells but they cannot normally function properly when exposed outside their natural environment due to lack of necessary elements needed inside them. By modifying these genes with specific chemical compounds, researchers may create better crop varieties through developing more effective methods for growing durable greenery materials.

Problems solved by technology

This patented describes how certain specific proteases called lysozyme act upon living things like trees or grasses during their life cycle. These enzymes help breakdown cell walls and absorb moisture around themselves while they work together to create more stable structures over longer periods. They play key roles in improving crop health and reducing environmental damage caused through extreme weather conditions. However, there may be some cases where these enzymatic activities could harm crops due to excessive salinity levels at high altitudes.
