笔者从中国农业科学院柑橘研究所获悉,近段时间,该所所长陈善春研究员团队在柑橘溃疡病和黄龙病抗病分子育种研究领域取得突破性进展,建立并利用基于CRISPR/Cas9的柑橘基因组编辑技术对柑橘感病基因CsL OB1启动子区进行定点编辑获得抗溃疡病柑橘材料,通过韧皮部特异表达抗菌肽基因Cecropin B获得对黄龙病耐性显著提高的转基因柑橘材料。有
The author learned from the Citrus Research Institute of Chinese Academy of Agricultural Sciences that in recent time, the director Chen Shanchun team of researchers made breakthroughs in citrus canker and yellow dragon disease resistant molecular breeding research. The establishment and utilization of CRISPR / Cas9-based citrus genome Editing technology to citrus susceptibility gene CsL OB1 promoter region of targeted editing anti-ulcer citrus materials, through the phloem specific expression of the antimicrobial peptide gene Cecropin B obtained a significant increase in resistance to yellow dragon’s disease transgenic citrus materials.
