一、主要研究领域与成果:
1.中药材新品种选育及规范化种植
指导陕西陕南三市、甘肃、青海、四川、广州、云南等地十余个县、20余家企业开展中药材规范化种植、野生资源抚育研究与生产;选育陕西道地、大宗中药材优良品系20余种,通过省级审定的山茱萸新品种4个;指导企业通过国家GAP认证2个;推广中药材规范化种植面积百万余亩,年均新增经济效益2.6亿元以上。
2.珍稀濒危药用植物快速繁育体系建设及推广应用
先后建立了白及、铁皮石斛、黄精等20余种珍稀、濒危药材组织培养、植株再生和优良种苗快速繁育技术体系。针对制约白及产业发展的瓶颈,建立了白及种质资源库,收集白及种质资源100余份,实现了白及菌根促生真菌的诱导、快速繁殖体系、温室直播体系、大田直播体系、实生苗的移栽及球茎的快速催芽方法等一体化的繁殖体系,建立了白及标准化、规模化、集约化的种苗快速繁育体系,攻克了白及种子在自然条件下萌发率低、发育周期长、繁殖系数低等问题,大幅提高了白及种子萌发率,降低了白及种植成本,解决了白及市场供求矛盾,给企业和药农带来了良好的经济效益。
3. 丹参次生代谢调控及分子机理研究
在国内外首次建立了丹参组织培养及外源高效遗传转化体系、丹参EST文库、转录组和miRNA基因数据库,为丹参成为次生代谢“模式药用植物”奠定了基础;先后克隆得到丹参丹酚酸和丹参酮合成途径的关键酶基因110余条;对丹参酚酸类合成途径以及萜类合成途径的关键酶基因进行遗传修饰,阐明SmPAL、SmRAS、SmCPS、SmGGPPS等关键酶基因的功能;在丹参中引入外源基因如拟南芥AtPAP1、金鱼草Delila和Rosea1 等转录因子,实现了丹参酚酸合成途径的高效调控,使丹参酚酸类化合物含量提高3倍以上。在此基础上,尝试多支路、多基因协同调控的基因操作方式,在丹参中过表达AtPAP1转录因子的同时,抑制丹参木质素合成途径关键基因SmCCR和SmCOMT,创新性地提出了丹参次生代谢物质合成的组合调控模式,该成果已在《Metabolic engineering》(IF:6.767)上发表;结合数字基因表达谱和代谢组学策略比较茉莉酸处理后丹参代谢网络中基因流和代谢流的变化规律,筛选并鉴定了一系列茉莉酸信号转导通路及酚酸类活性成分合成途径的关键基因和调控靶点,明确了COI1-JAZ-MYB信号转导单元和MYB-bHLH-TTG1转录复合体参与调控丹酚酸类物质合成的分子机制,揭示了bHLH依赖的MYB-bHLH复合体对bHLH的自激活反馈式转录调控方式,描绘了丹参中茉莉酸信号的识别、转导及丹酚酸合成的调控通路,部分成果已在《Scientific reports》(IF:5.578)上发表。
