Despite the recent discovery that trehalose synthesis is important for plant development and abiotic stress tolerance, the effects of trehalose on biotic stress responses remain relatively unknown. In this study, we demonstrate that TREHALOSE PHOSPHATE

叶肉导度(g_m)指叶肉细胞内部的CO_2扩散能力,它是叶肉细胞阻力的倒数.光合作用研究的早期,研究者们多将叶肉细胞对CO_2的扩散阻力视为零,即假定g_m无穷大,而忽略了其对光合作用的限制.但近来的研究表明,g_m是有限的,并随着环境条件的改变而发生变化,此外,g_m的大小直接决定了CO_2在叶片内的扩散量,进而影响到植物光合效率的高低.因此,g_m的估算对于植物光合能力的评估意义重大.目前,气
以渭北旱作苹果园4种覆盖模式(秸秆覆盖、锯末覆盖、森林土覆盖、清耕对照)土壤为研究对象,在土壤基本理化指标及土壤酶活性测定的基础上,利用荧光定量PCR(q-PCR)和Illumina HiSeq高通量测序技术对土壤细菌群落结构和多样性进行分析。研究结果表明,各覆盖处理较对照显著提高了0～20cm土层水分、有机质和全氮含量,降低了土壤pH;同时显著提高土壤脲酶、蔗糖酶和过氧化氢酶活性;各覆盖处理下土
The rhizosheath, a layer of soil particles that adheres firmly to the root surface by a combination of root hairs and mucilage, may improve tolerance to drought stress. Setaria italica(L.) P. Beauv.(f
The phytohormone abscisic acid(ABA) is an important mediator in the drought response, participating in, among other processes, stomatal movements. In Arabidopsis thaliana, the serine/threonine protein
总结了光信号(光强、光质、光周期及昼夜节律中光暗变化)对叶绿素含量及其生物合成途径中相关基因的影响。重点归纳了光信号途径中主要转录因子对叶绿素合成基因的调控机制,强调了表观遗传修饰在光调控叶绿素合成中的重要作用,以期探索光调控叶绿素积累的有效途径及靶标分子,为利用基因工程和环境调控手段定向调控有重要生物学功能的叶绿素提供理论基础。
In response to phosphate(Pi) deficiency, it has been shown that micro-RNAs(miRNAs) and mRNAs are transported through the phloem for delivery to sink tissues. Growing evidence also indicates that long
Crop residue retention has been considered a practicable strategy to improve soil organic carbon(SOC) and total nitrogen(TN), but the effectiveness of residue retention might be different under varied
There is limited information on carbon sequestration efficiency(CSE) of soil aggregates in upland and paddy soils under long-term fertilization regimes. In a red soil region of southern China, an upla
文章从水文遥测终端技术在水文情报预报中的作用出发,分析和探讨了该技术的工作原理、通信特征和具体应用,以期为同行提供参考依据。
针对当前多源光栅成像信息融合方法存在的时间长、质量差等缺陷,设计了基于Contourlet变换的多源光栅成像信息融合方法。首先分析当前多源光栅成像信息融合的研究现状,并指出各种多源光栅成像信息融合方法的局限性,然后提取多源光栅成像信息,采用主成分分析法对多源光栅成像信息进行处理,最后采用Contourlet变换得到低频分量共同特征与独特特征,并根据联合稀疏表示法对低频信息分量进行融合,采用活跃度评
