Forest trees may harbor naturally occurring exon disruptive variants (DVs) in their gene sequences, which potentially impact important ecological and economic phenotypic traits. However, the abundance and molecular regulation of these variants remain largely unexplored. Here, 24,420 DVs were identified by screening 1014 Populus trichocarpa full genomes. The identified DVs were predominantly heterozygous with allelic frequencies below 5% (only 26% of DVs ha... ...点击完成人机验证后继续浏览

森林树木的基因序列中可能存在自然发生的外显子破坏变异（DVs），这些变异可能会影响重要的生态和经济表型特征。然而，这些变异的数量及其分子调控机制仍然很大程度上未被探索。通过对1014个Populus trichocarpa全基因组进行筛选，共鉴定出24,420个DVs。鉴定到的DVs大多数为杂合子，并且等位基因频率低于5%（只有26%的DVs频率大于5%）。利用共同园艺栽培的树木，在发育中的木质部中评估了这些DVs对基因表达变异的影响，结果显示它们的基因表达可以显著改变，特别是对于纯合子DVs（根据研究的共同花园的不同，占比在27%-38%之间）。进一步探究了DVs与13种木材品质性状的相关性，发现其中148个被鉴定出的DVs关联中，有15个与一种以上的木材性质相关联，并且六个基因在其编码序列中有多个DVs与木材特性有关。大约三分之一的与木材属性变异相关的DVs还显示出显著的基因表达变化，证实了它们的影响并非偶然。这些发现为利用树木生物技术有针对性地引入纯合突变提供了潜在途径，尽管DVs如何直接对木材形成产生影响的确切机制尚待解析，但本研究为此进一步的研究奠定了基础。
