Faster onset of photoprotection could potentially increase biomass accumulation. Indeed, this has been realized in tobacco VPZ lines by overexpression of three photoprotective proteins in parallel. To explore the range of application of this approach, we generated Arabidopsis VPZ lines. These lines triggered photoprotection more rapidly, but growth rate and biomass accumulation were impaired under fluctuating light. This implies that the strategy might interfere with other mechanisms controlling excitation energy distribution, or with source–sink relationships or plastid signalling.

光保护的加速放松损害了拟南芥的生物量积累
光保护的更快开始可能会增加生物量的积累。事实上，这已经在烟草VPZ品系中通过同时过表达三种光保护蛋白来实现。为了探索这种方法的应用范围，我们生成了拟南芥VPZ品系。这些细胞系更快地触发光保护，但生长速率和生物量积累在波动光下受到损害。这意味着该策略可能会干扰控制激发能量分布的其他机制，或者干扰源-库关系或质体信号传导。
