  烟粉虱传播的番茄黄化曲叶病毒病造成世界范围内番茄品质和产量的降低,甚至绝收.近年来,人们发现长链非编码RNA(lncRNAs)在动植物生长发育中起着非常重要的作用,然而,lncRNAs在植物抵御DNA病毒侵染过程中的作用未见报道.我们通过对番茄接种黄化曲叶病毒的链特异性转录组测序,建立了番茄长链非编码RNA的预测流程,并预测到1565条lncRNAs,其中包括基因间长链非编码RNA和反义RNA.选择部分接种前后差异表达的lncRNAs进行瞬时沉默和过表达分析,进一步明确了lncRNAs在抗TYLCV中的作用.同时,我们还发现一些lncRNAs作为内源microRNAsmimics,通过调节micoRNA下游靶基因的表达从而调控番茄的抗病性.此外,我们还发现lncRNAs对番茄的发育也具有重要影响.

高产与优质是水稻育种的两大最主要目标。胚乳是组成水稻种子的最重要部分,其发育直接影响稻米的产量和品质;淀粉是稻米胚乳的最主要成分,一般占胚乳重量的90%及以上,构成了人类粮食的主体部分。因此,稻米淀粉的组成与结构是决定稻米品质及其适用性的最重要因素。全球水稻种资源丰富,稻米品质性状变异极为多样,深入研究淀粉合成相关基因的变异及调控机制对于揭示稻米品质性状遗传变异和改良品质具有重要意义。近年来,我们
