How does having more than one genome give plant species an advantage when it comes to adaptive evolution? Recent molecular studies have shown that altered patterns of gene expression may offer polyploids a broader phenotypic range than that of their progenitors.
当涉及适应性进化时,拥有多个基因组如何赋予植物物种优势?最近的分子研究表明,与它们的祖先相比,基因表达模式的改变可能为多倍体提供更广泛的表型范围。
