Abstract: The present disclosure relates, in some embodiments, to materials, systems, organisms, and methods for enhancing abiotic stress tolerance (e.g., cold, salinity, drought, wind), increasing biomass, and/or altering lignin composition in plants. For example, enhancing abiotic stress tolerance may be achieved using a plant-specific family of transcription factors is APETALA2 (AP2), that includes c-repeat binding factor (e.g., CBF1, CBF3) and AP37 nucleic acids and/or polypeptides. In some embodiments, increasing biomass may be achieved by altering expression of gibberellin oxidases (e.g., GA3ox3/GA2ox4) nucleic acids and/or polypeptides. Altering lignin composition may be achieved by suppression of stem-thickening in pith (e.g., STP1) nucleic acids and/or polypeptides.

Abstract translation: 在一些实施方案中，本公开涉及用于增强非生物胁迫耐受性（例如，冷，盐度，干旱，风），增加生物质和/或改变植物中木质素组成的材料，系统，生物体和方法。 例如，可以使用植物特异性转录因子家族APETALA2（AP2）（其包括c重复结合因子（例如CBF1，CBF3）和AP37核酸和/或多肽）来实现增强非生物胁迫耐受性。 在一些实施方案中，可通过改变赤霉素氧化酶（例如GA3ox3 / GA2ox4）核酸和/或多肽的表达来实现增加的生物量。 改变木质素组合物可以通过抑制髓（例如STP1）核酸和/或多肽中的茎增稠来实现。
