为探究WALLS ARE THIN(WAT1)在木本植物中木材形成以及响应胁迫中的作用,利用生物信息学工具进行分析,并以巨桉(Eucalyptus grandis)为材料克隆EgrWAT1S及其另一转录本EgrWAT1L,通过实时荧光定量PCR(qRT-PCR)探究其在不同组织、节间以...为探究WALLS ARE THIN(WAT1)在木本植物中木材形成以及响应胁迫中的作用,利用生物信息学工具进行分析,并以巨桉(Eucalyptus grandis)为材料克隆EgrWAT1S及其另一转录本EgrWAT1L,通过实时荧光定量PCR(qRT-PCR)探究其在不同组织、节间以及响应胁迫时的表达模式。结果表明:EgrWAT1S在韧皮部表达量较高,而EgrWAT1L主要表达在根部。在茉莉酸甲酯(MeJA)、水杨酸(SA)处理和盐胁迫以及缺磷、缺硼处理时,其表达存在着明显不同的模式,在MeJA、SA处理时甚至存在着相反的表达模式。这些结果表明EgrWAT1L基因可能通过转录调控来影响EgrWAT1S表达和进一步的蛋白翻译来响应激素和胁迫处理。为进一步研究WAT1基因在巨桉生长发育过程中的作用和调控方式提供基础,也为将来桉树的分子育种提供可能。展开更多
The ameliorative effect of fulvic acid(0, 300, and 600 mg L-1) on photosystem II and antioxidant enzyme activity of the rapeseed(Brassica napus L.) plant under water stress(60, 100, and 140 mm evaporation from class A...The ameliorative effect of fulvic acid(0, 300, and 600 mg L-1) on photosystem II and antioxidant enzyme activity of the rapeseed(Brassica napus L.) plant under water stress(60, 100, and 140 mm evaporation from class A pan) was studied using split plots in a randomized complete block design with three replications. Results indicated that application of fulvic acid(FA) improved the maximum quantum efficiency of PSII(Fv/Fm)and performance index(PI) of plants under both well-watered and limited-water conditions. The time span from Foto Fmand the energy necessary for the closure of all reaction centers was significantly increased, but the size of the plastoquinone pool was reduced with increasing water stress levels. Plants treated with FA had higher peroxidase and catalase activities under all irrigation conditions. Activities of ascorbate peroxidase and superoxide dismutase in plants increased with increasing water stress. Malondialdehyde increased under severe water stress, but application of FA significantly decreased lipid peroxidation. Production of reactive oxygen species(ROS) is a common phenomenon in plants under stress. Under this condition, the balance between the production of ROS and the quenching activity of antioxidants is upset, often resulting in oxidative damage. In this study, application of FA significantly increased fluorescence of chlorophyll a, inhibiting ROS production and enhancing antioxidant enzymes activity that destroyed ROS. Thus, ROS in plant cells was reduced under water stress by application of FA and consequently lipid peroxidation was reduced.展开更多
