水稻、小麦等作物由于受光呼吸反应的影响,光合作用效率比正常情况下降低30~50%,严重制约了生长和高产。要加速其生长,实现高产,就必须对光合作用中起主要作用的核酮糖二磷酸羧化酶进行研究,并重点对其中的小亚基进行解剖、改造,弄清它的精细结构,以及影响光合效率的原因,这是近20年来各国学者共同探讨的难题。
The photosynthesis efficiency of rice, wheat and other crops is reduced by 30-50% under normal conditions due to the photorespiration and respiration, which severely restricts the growth and yield. In order to accelerate its growth and achieve high yield, it is necessary to study the ribulose bisphosphate carboxylase which plays a major role in photosynthesis and to focus on the dissection and modification of its small subunit and its fine structure, and The reason of affecting the photosynthetic efficiency is a difficult problem that scholars of all countries have discussed in the past 20 years.
