同質・異質倍数体生物の環境適応機構のゲノム基盤

第二年，我们成功地在杀菌剂和高盐浓度两种不同的胁迫下进行了严酷度梯度递增的实验。正如预期的那样，每个连续的区域都需要不同的机制来让真菌应对新环境。这种变异的适应速度代表了真菌在每个新区域重新调整自己以适应新压力的速度。我们还在其他培养实验中进行了混合竞争试验，将具有密切相关亚基因组的杂交体-二倍体对的起始菌落设置为50:50的混合物。还进行了纳米孔测序以检索基因组数据。这些结果正在被深入分析。

In the second year, we successfully conducted experiments with gradients of increasing harshness with two different kinds of stress, such as fungicide and high salt concentration. As expected, each successive zone required a different mechanism for the fungi to cope with the new environment. The speed of adaptation in this variant became a proxy of how fast the fungi can reorient themselves to new stress with each new zone. We also conducted mixing competition assay into additional culture experiments by making the starting colony a 50:50 mixture of hybrid-diploid pair that share closely related subgenomes. Nanopore sequencing was also conducted to retrieve genomic data. The results are being analyzed in depth.
