Abstract: | In most higher plants, mature dry seeds have no chloroplasts but etioplasts. Here we show that in a hydrophyte, lotus (Nelumbo nucifera), young chloroplasts already exist in shoots of mature dry seeds and that they give rise to mature chloroplasts during germination, even in darkness. These shoots contain chlorophyll and chlorophyll-binding proteins CP1 and LHCP. The unique features of chloroplast formation in N. nucifera suggest a unique adaptive strategy for seedling development correlated with the plant's habitat. |
