A study of pyrroloquinoline quinone on Pei-Chiao (Musa spp.) growth and biocontrol improvement

, 2006
香蕉是世界上重要的糧食作物之一，但深受香蕉黃葉病害之影響導致產量受限，因此解決此問題為當前首要之任務。前人實驗結果證實有接種Burkholderia sp. 869T2的北蕉平均株高增加32.6公分，發病率降低21.1%。而在本研究中於溫室實驗中同樣驗證了869T2接種於北蕉之促進生長及抗病之效果，有效降低黃葉病的罹病程度。於轉錄基因體分析中發現869T2體內合成Pyrroloquinoline quinone (PQQ)之基因組有高表現量。藉由使用PQQ對北蕉進行生長測試 ...

Triple-Model Immunoassays with the Self-Assemblies of Three-in-One Small Molecules as Signaling Labels

Biosensors
Multiple-mode immunoassays have the advantages of self-correction, self-validation, and high accuracy and reliability. In this work, we developed a strategy for the design of triple-mode immunoassays with the self-assemblies of three-in-one small ...

Pre-conditioning with PQQ during pregnancy alleviates LPS-induced placental damage and improves the fetal survival and growth in mice

Frontiers in Endocrinology
BackgroundIntrauterine infection is a major cause of preterm birth, fetal demise, and growth restriction. Placental damage resulting from such infections plays a central role in mediating these adverse outcomes.
