Land plants co-speciate with a diversity of continually expanding plant specialized metabolites(PSMs) and root microbial communities(microbiota).Homeostatic interactions between plants and root microbiota are essential for plant survival in natural environments.A growing appreciation of microbiota for plant health is fuelling rapid advances in genetic mechanisms of controlling microbiota by host *** have long been proposed to mediate plant and single microbe ***,the effects of PSMs,especially those evolutionarily new PSMs,on root microbiota at community level remain to be ***,we discovered sesterterpenes in Arabidopsis thaliana,produced by recently duplicated prenyltransferase-terpene synthase(PT-TPS) gene clusters,with neo-functionalization.A single-residue substitution played a critical role in the acquisition of sesterterpene synthase(sesterTPS) activity in Brassicaceae ***,we found that the absence of two root-specific sesterterpenoids,with similar chemical structure,significantly affected root microbiota assembly in similar *** results not only demonstrate the sensitivity of plant microbiota to PSMs but also establish a complete framework of host plants to control root microbiota composition through evolutionarily dynamic PSMs.

在对SEBS模型的有关参数进行订正的基础上,利用MODIS遥感数据结合地表气象观测数据,对黄淮海地区地表能量通量进行了估算。将SEBS估算结果先与北京顺义定量遥感综合试验(QRSLSP/Shunyi)实测结果进行对比分析,然后与郑州的大孔径闪烁仪(LAS)观测的感热通量进行对比分析。结果表明,SEBS估算的通量与二者的实测结果相当一致。因此,利用改进后的SEBS模型估算的黄淮海地区地表能量通量具有一定的精度,可满足区域日蒸散量计算等的需求。

文章给出了青藏高原能量水分循环研究的概况和总结,着重估计了能量平衡各分项和湍流热通量等。在能量平衡的计算基础上,尽管能量不平衡的原因解释仍有争论并且没有解决,但我们揭示了GAME/Tibet试验观测资料中能量不平衡现象。我们发现估算的潜热通量比实际观测的要高许多。然而,根据能量平衡假设的计算结果和SEBS的估算一致性很好。在此基础上可以归纳出差异主要由GAME/Tibet试验观测资料中能量不平衡引起,潜热通量的实际观测可能偏小。
