Plant response to various stress conditions often results in expression of common genes, known as stress-responsive/inducible genes. Accumulating data point to a common, yet elusive process underlying the response of plant cells to stress. Evidence derived from transcriptome profiling of shoot apical meristem stem cells, dedifferentiating protoplast cells as well as from senescing cells lends support to a model in which a common response of cells to certain biotic and abiotic stresses converges on cellular dedifferentiation whereby cells first acquire a stem cell-like state before assuming a new fate.
植物对各种胁迫条件的反应通常会导致共同基因的表达,这些基因被称为应激响应/诱导基因。越来越多的证据表明,植物细胞对胁迫的反应存在一个共同但难以捉摸的过程。从茎尖分生组织干细胞、去分化原生质体细胞以及衰老细胞的转录组谱分析中获得的证据支持这样一种模式,即细胞对某些生物和非生物胁迫的共同反应集中在细胞去分化上,即细胞首先获得类似于干细胞的状态,然后再获得新的命运。
