水稻叶片自然衰老过程中Rubisco大亚基的含量变化
水稻 叶绿素b 突变体 衰老 光合放氧 1,5二磷酸核酮糖羧化酶/加氧酶
2009/9/23
以水稻低叶绿素b突变体及其野生型（镇恢249）为材料，研究了水稻第5叶叶片自然衰老过程中光合放氧、Rubisco大亚基含量变化以及对胰蛋白酶敏感性的变化，并通过喷施不同的抗氧化剂以及氧化剂研究其对Rubisco大亚基含量变化的影响。结果表明，叶片全展后随着衰老进程，突变体与野生型光合放氧速率、Rubisco大亚基相对含量呈下降趋势，抗氧化剂可以不同程度地缓解Rubisco大亚基含量的下降，而氧化剂...
Photosynthetic Control Factors in a Single Leaf of Sweet Potato, Ipomoea batatas Lam : 3. Estimation of in vivo rubisco activity from the CO2 exchange rate of a peeled leaf
CO2 exchange rate Ipomoea batatas Lam Leaf epidermis peeling Rubisco activity
2009/7/30
Rubisco (ribulose 1, 5-bisphosphate carboxylase/oxygenase) activity is the prime determinant for CO2 exchang rate (CER) at the beginning of the photosynthetic reaction, and hence the rubisco activity ...
Correlation of Leaf Nitrogen,Chlorophyll and Rubisco Contents with Photosynthesis in a Supernodulating Soybean Genotype Sakukei 4
Chlorophyll Glycine max Leaf nitrogen Photosynthesis Rubisco Soybean Supernodulation
2009/7/24
Soybean requires more nitrogen (N) than gramineous crops because it accumulates a large amount of N in seeds, and its photosynthetic rate per leaf N is low. The supernodulating genotype Sakukei 4 has...
Screening of High kcat Rubisco among Poaceae for Improvement of Photosynthetic CO2 Assimilation in Rice
kcat Km Oryza sativa L. Photosynthesis Rice Rubisco
2009/7/21
The activity of ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) is a major limitation of photosynthetic CO2 assimilation in C3 plants. In order to find useful Rubisco for improvement of phot...
小麦Rubisco活化酶的纯化及其活性特性
小麦 Rubisco活化酶 ATP
2010/1/22
试验以小麦为材料,纯化了Rubisco活化酶,经SDS聚丙烯凝胶电泳鉴定呈2条蛋白质谱带,分子量为41000和45000,利用14 C标记法测定并探讨了Rubisco活化酶的活性,并发现Rubisco活化酶在纯化和储藏过程中都需要ATP以稳定其活性。
