Phosphoenolpyruvate carboxylase (PEPC) catalyzes the initial fixation of CO2 in C4 plants. Under the control of the rice Rubisco small subunit promoter, cDNA of a C4 SiPPC gene cloned from Seteria italica was introduced into Japonica rice by Agrobacterium-mediated transformation. Integration of the gene was confirmed by PCR analysis. RT-PCR showed(More)
Taking four maize inbred lines with different photosynthetic rate and their two hybrids as test materials, the diurnal variations of their photosynthesis parameters in silking stage were measured to study the heterosis of photosynthetic performance. The results showed that the net photosynthetic rate (P), transpiration rate (Tr) and stomatal conductance(More)

The study shows that there existed a significant relationship between the new branch growth of grapes and temperature, especially effective accumulate temperature. Kyoho had the fastest new branch growth rate among all varieties, which was 0.43433 cm in length with raising 10 degrees C while effective accumulate temperature was over 190.68 degrees C.(More)
