最近科学家利用Plantarray植物逆境生理表型平台发表文章,文章题为High-Throughput physiology-based stress response phenotyping: Advantages,applications and prospective in horticultural plants 发表在Horticultural Plant Journal。文中提出了形态胁迫反应表型(Morphology-based stress responses phenotyping)以及生理胁迫表型(Physiology-based stress response phenotyping)的概念。
非生物胁迫是指环境影响如干旱(缺水),盐度,浇水过量,极端温度(冷、霜和热)以及有毒物质,这些非生物胁迫可负面影响作物以及其它植物生长、发育、产量以及种子品质。
现代作物产量高,但易受到非生物胁迫影响。因基因环境互作的复杂性,提升作物胁迫反应面临巨大挑战, 特别是气候变化期间。要满足全球日益增长的食品需求,研究人员在努力培育适应恶化条件的作物优化品系。
Plantarray高通量植物生理研究平台提供了简单易用的软硬件工具,可自动控制实验阵列每个花盆的灌溉处理(品质和数量),分析每个植株对控制处理的反应。
通过测定检测施加环境胁迫条件的植物的特定胁迫阈值,系统显著降低了研究植物应对缺水环境的研究时间和精力,并与田间结果高度相关联。
使用Plantarray方案的优势:
高通量功能性状分析
持续测量多尺度功能(生理)性状如生长速率,蒸腾速率,水利用效率, 气孔导度,根活力等。
同时控制不同土壤和水应用场景(例如,干旱、盐度和/或化学品)
即时反馈和实时深度分析植物性能,给出清晰图表
4到6周即可快速给出结果

Abstract
Phenomics is a new branch of science that provides high-throughput quantification of plant and animal traits at systems level. The last decade has witnessed great successes in high-throughput phenotyping of numerous morphological traits, yet major challenges still exist in precise phenotyping of physiological traits such as transpiration and photosynthesis. Due to the highly dynamic nature of physiological traits in responses to the environment, appropriate selection criteria and efficient screening systems at the physiological level for abiotic stress tolerance have been largely absent in plants. In this review, the current status of phenomics techniques was briefly summarized in horticultural plants. Specifically, the emerging field of high-throughput physiology-based phenotyping, which is referred to as “physiolomics”, for drought stress responses was highlighted. In addition to analyzing the advantages of physiology-based phenotyping over morphology-based approaches, recent examples that applied high-throughput physiological phenotyping to model and non-model horticultural plants were revisited and discussed. Based on the collective findings, we propose that high-throughput, non-destructive, and automatic physiological assays can and should be used as routine methods for phenotyping stress response traits in horticultural plants.
