Epigenetic variation plays an important role in plant growth and development, including DNA methylation, histone modification, chromosome remodeling, and RNA interference and so on.
表观遗传变异对于植物的生长发育起着重要作用，主要包括DNA甲基化、组蛋白修饰、染色体重塑和RNA干涉等。
But it's hard to tell in most natural populations whether inheritance is due to DNA sequence variation or epigenetic changes.
但在自然界大多数种群中，很难判断遗传是否源于DNA序列改变或者表观基因变异。
Many researchers say these so-called epigenetic changes are as important as genomic variation to controlling cell function and, ultimately, an individual's health.
许多研究者认为这种所谓的次生变化在控制细胞功能及最终控制个体健康方面与基因组的变化同样重要。
Epigenetic is the latest biological science in recent years, which mainly researches gene function reversible and heritable variation without DNA sequence changes.
表观遗传学是近年来新兴起的生物学学科，主要研究在没有DNA序列改变情况下基因功能可逆的、可遗传的变异。
Increasingly, biologists are finding that non-genetic variation acquired during the life of an organism can sometimes be passed on to offspring-a phenomenon known as epigenetic inheritance.
越来越多的生物学家发现了一个被称为表观遗传的现象- - - - - -生物有机体后天获得的非遗传变异有时可以被遗传下去。
