盐地碱蓬(Thellungiella Salsugina)是拟南芥的近亲，是研究非生物胁迫耐受性的极端生物模型。我们提出了盐藻基因组的草案序列，基于对7条染色体的134倍覆盖，编码能力至少为28,457个基因。该基因组为研究植物非生物胁迫耐受性的遗传基础的防御机制的性质提供了资源和证据。比较基因组学和实验分析表明，盐碱草中与阳离子转运、脱落酸信号转导和产蜡相关的基因可能是其在胁迫环境中成功的原因。
Thellungiella salsuginea, a close relative of Arabidopsis, represents an extremophile model for abiotic stress tolerance studies. We present the draft sequence of the T. salsuginea genome, assembled based on similar to 134-fold coverage to seven chromosomes with a coding capacity of at least 28,457 genes. This genome provides resources and evidence about the nature of defense mechanisms constituting the genetic basis underlying plant abiotic stress tolerance. Comparative genomics and experimental analyses identified genes related to cation transport, abscisic acid signaling, and wax production prominent in T. salsuginea as possible contributors to its success in stressful environments.
