Abstract
Chlorophyll a/b-binding protein genes (Cab genes) can be extremely sensitive to light. Transcript accumulation following a red light pulse increases with fluence over 8 orders of magnitude (L.S. Kaufman, W.F. Thompson, W.R. Briggs [1984] Science 226: 1447-1449). We have constructed fluence-response curves for individual Cab genes. At least two Cab genes (Cab-8 and AB96) show a very low fluence response to a single red light pulse. In contrast, two other Cab genes (AB80 and AB66) fail to produce detectable transcript following a single pulse of either red or blue light but are expressed in continuous red light. Thus, very low fluence responses and high irradiance responses occur in the same gene family.
摘要
叶绿素a/b结合蛋白基因（Cab基因）对光极为敏感。红光脉冲后的转录本积累随光通量增加，跨越8个数量级（L.S.考夫曼、W.F.汤普森、W.R.布里格斯[1984]《科学》226: 1447 - 1449）。我们构建了单个Cab基因的光通量响应曲线。至少两个Cab基因（Cab - 8和AB96）对单个红光脉冲表现出极低光通量响应。相比之下，另外两个Cab基因（AB80和AB66）在单个红光或蓝光脉冲后未能产生可检测到的转录本，但在持续红光下表达。因此，极低光通量响应和高辐照度响应出现在同一个基因家族中。
