Abstract

The invention relates to a cucumber CsERF004 gene as well as an encoding protein and application thereof. The invention provides a cucumber disease-resistance related gene CsERF004 gene as well as an encoding protein and application thereof. A cDNA (complementary Deoxyribonucleic Acid) nucleotide sequence of the cucumber CsERF004 gene is shown as SEQ ID NO: 1 in a sequence table. An amino acid sequence of the encoding protein is shown as SEQ ID NO: 2. The CsERF004 gene overexpression obviously improves the content of free-state salicylic acid in cucumbers, and the cucumber CsERF004 gene has obvious resistance on downy mildew and target leaf spot at a seedling period. The invention provides a new solution way for reducing diseases and insect pests of the cucumbers and improving the disease resistance of the downy mildew and target leaf spot of the cucumbers. The cucumber CsERF004 gene provided by the invention is used for improving the resistance on the downy mildew and target leaf spot of the cucumbers.

Description

technical field

[0001] The present invention relates to CsERF004 gene and its coded protein and application. Background technique

[0002] Cucumber is a staple vegetable that is eaten as a tender fruit. In production, cucumbers are susceptible to infection by a variety of pathogenic bacteria, which seriously affects their yield and quality. Cucumber downy mildew and Corynespora leaf spot are important diseases in cucumber production. The disease spreads rapidly and poses a great threat to cucumber production. The long-term use of chemical agents for disease control has resulted in resistance to downy mildew and Corynesporium leaf spot. At the same time, a large amount of pesticide residues will cause environmental pollution and endanger human health and other problems. The green, economical and effective control method is still breeding and utilizing disease-resistant varieties. Breeding single disease-resistant varieties can no longer solve the serious impact of diseas...
