“…Meanwhile, it can lead to leaf bleaching, slow growth and intense photo-inhibition (Sun et al, 2003;Ding et al, 2003;Shao et al, 2008 ;Casati et al, 1999). There are some research proved that the expression of NADP-ME gene from C 4 plant in C 3 plant may bring harm for chloroplast (Ding et al, 2003;Ngele et al, 2009). So, it can include that transfer NADP-ME gene from C 4 plant is not helpful for improving C 3 plant photosynthetic rate (Casati et al, 1999;Sun et al, 2003;Ding et al, 2003 andChi et al, 2004b).…”
