There was no obvious difference in ratio of Chl a/b between mutants and wildtype, while F v/ F m in mutants increased to some extents. The total xanthophyll pool (V+A+Z) increased significantly in lutein deficient mutants (lut 2 and lut 2 npq 1).

• 与WT相比 ；3个突变体的叶绿素a/b没有明显的差异 ；Fv/Fm 则有不同幅度的增加 ；缺乏lutein的突变体lut2 和lut2 npq1的叶黄素循环库 (V +A +Z)显著增大 .
