Abstract
:Citrus greening, also called Huanglongbing (HLB), is one of the most destructive citrus diseases worldwide. It is caused by the fastidious gram-negative α-proteobacteria bacterium Candidatus Liberibacter asiaticus (CLas) and vectored by the Asian citrus psyllid (ACP), Diaphorina citri. Currently, there is no cure for HLB, no compounds have been successful in controlling HLB, and no sustainable management practices have been established for the disease. Thus, searching for alternative citrus greening disease mitigation strategies is considered an urgent priority for a sustainable citrus industry. The aim of this study was to use compounds extracted from oak, Quercus hemisphaerica, and to assess the antibacterial effects of these against CLas-infected citrus plants. The application of aqueous oak leaf extracts showed substantial inhibitory effects against CLas in citrus plants and the activity of genes related to starch. Significant differences were also observed in plant phenotypic and physiological traits after treatments. Citrus plants treated with oak extracts displayed an increase in stomatal conductance, chlorophyll content and nutrient uptake concurrently with a reduction of CLas titer, when compared to citrus plants treated with just water. The information provided from this study suggests a new management treatment program to effectively deal with the HLB disease.
摘 要
: 柑橘绿化又称黄龙病 (HLB),是世界范围内危害最大的柑橘病害之一。它是由挑剔的革兰氏阴性 α 变形菌细菌candidus Liberibacter asiaticus (CLas) 引起的,由亚洲柑橘psyllid (ACP) Diaphorina citri为载体。目前,HLB没有治愈方法,没有化合物成功控制HLB,也没有建立针对该疾病的可持续管理实践。因此,寻找替代柑橘绿化疾病缓解策略被认为是可持续柑橘产业的迫切优先事项。本研究的目的是使用从橡树、栎中提取的化合物,并评估这些化合物对感染柑橘属植物的抗菌作用。水橡树叶提取物的应用显示了对柑橘植物中的CLas和淀粉相关基因活性的显著抑制作用。处理后在植物表型和生理性状上也观察到显著差异。与仅用水处理的柑橘植物相比,用橡木提取物处理的柑橘植物表现出气孔导度、叶绿素含量和营养吸收的增加,同时CLas滴度降低。从这项研究中提供的信息表明,一个新的管理治疗方案,以有效地处理HLB病。
期刊介绍
《PLANT PHYSIOLOGY AND BIOCHEMISTRY》 (点击进入期刊详情)
英文简介 : Plant Physiology and Biochemistry publishes original theoretical, experimental and technical contributions in the various fields of plant physiology (biochemistry, physiology, structure, genetics, plant-microbe interactions, etc.) at diverse levels of integration (molecular, subcellular, cellular, organ, whole plant, environmental). Opinions expressed in the journal are the sole responsibility of the authors and publication does not imply the editors' agreement. Manuscripts describing molecular-genetic and/or gene expression data that are not integrated with biochemical analysis and/or actual measurements of plant physiological processes are not suitable for PPB. Similarly, applied agronomic studies that generate no new, fundamental insights in plant physiological and/or biochemical processes are not suitable for publication in PPB. Plant Physiology and Biochemistry publishes several types of articles: Reviews, Papers and Short Papers. Articles for Reviews are either invited by the editor or proposed by the authors for the editor's prior agreement. Reviews should not exceed 40 typewritten pages and Short Papers no more than approximately 8 typewritten pages. The fundamental character of Plant Physiology and Biochemistry remains that of a journal for original results.
中文简介 : (来自Google、百度翻译) 《植物生理学与生物化学》以不同层次的整合(分子、亚细胞、细胞、器官、整株植物、环境)出版了植物生理学(生物化学、生理学、结构、遗传学、植物与微生物相互作用等)各个领域的原始理论、实验和技术贡献。发表在杂志上的观点是作者的唯一责任,出版并不意味着编辑的同意。 未与生物化学分析和/或植物生理过程的实际测量相结合的分子遗传学和/或基因表达数据的手稿不适合用于PPB。同样,在植物生理和/或生物化学过程中没有产生新的、基本的见解的应用农艺研究也不适合在PPB上发表。 植物生理学和生物化学发表几种类型的文章:评论、论文和短文。评论文章要么由编辑邀请,要么由作者提出,由编辑事先同意。评审不应超过40个打字页数,短文不应超过8个打字页数。植物生理学和生物化学的基本特征仍然是期刊的原始结果。
