  Improved Chemical Synthesis of UDP-Galactofuranose

  摘要：

  [GRAPHICS]A reliable and efficient synthetic route to UDP-alpha -D-galactofuranose (UDP-Galf) has been developed. Reaction of UMP-N-methylimidazolide with Galf 1-phosphate proceeds rapidly to provide UDP-Galf with excellent reproducibility and in a yield approximately twice as high as those reported previously.

  This invention relates generally to nucleic acid sequences encoding proteins that are associated with abiotic stress responses and abiotic stress tolerance in plants. This invention further relates to transformed plant cells with altered metabolic activity compared to a corresponding non-transformed, wild-type plant cell, wherein the metabolic activity is altered by transformation with a Stress-Related Protein (SRP) coding nucleic acid and results in increased tolerance and/or resistance to an environmental stress as compared to a corresponding non-transformed, wild-type plant cell.

  本发明一般涉及编码与植物非生物胁迫反应和非生物胁迫耐受性有关的蛋白质的核酸序列。本发明进一步涉及与相应的非转化野生型植物细胞相比代谢活性发生改变的转化植物细胞，其中代谢活性通过用胁迫相关蛋白（SRP）编码核酸进行转化而发生改变，并导致与相应的非转化野生型植物细胞相比对环境胁迫的耐受性和/或抗性增强。
