| Abstract |
Cryptochromes are flavoprotein photoreceptors first identified in Arabidopsis thaliana, where they play key roles in growth and development. Subsequently identified in prokaryotes, archaea, and many eukaryotes, cryptochromes function in the animal circadian clock and are proposed as magnetoreceptors in migratory birds. Cryptochromes are closely structurally related to photolyases, evolutionarily ancient flavoproteins that catalyze light-dependent DNA repair. Here, we review the structural, photochemical, and molecular properties of cry-DASH, plant, and animal cryptochromes in relation to biological signaling mechanisms and uncover common features that may contribute to better understanding the function of cryptochromes in diverse systems including in man. |

| Abstract |
The process of adaptation is the result of stabilising selection caused by two opposite forces: protection against an unfavourable season (survival adaptation), and effective use of growing resources (capacity adaptation). As plant species have evolved different life strategies based on different trade offs between survival and capacity adaptations, different phenological responses are also expected among species. The aim of this study was to compare budburst responses of two opportunistic species (Betula pubescens, and Salix x smithiana) with that of two long-lived, late successional species (Fagus sylvatica and Tilia cordata) and consider their ecological significance. Thus, we performed a series of experiments whereby temperature and photoperiod were manipulated during dormancy. T. cordata and F. sylvatica showed low rates of budburst, high chilling requirements and responsiveness to light intensity, while B. pubescens and S. x smithiana had high rates of budburst, low chilling requirements and were not affected by light intensity. In addition, budburst in B. pubescens and S. x smithiana was more responsive to high forcing temperatures than in T. cordata and F. sylvatica. These results suggest that the timing of growth onset in B. pubescens and S. x smithiana (opportunistic) is regulated through a less conservative mechanism than in T. cordata and F. sylvatica (long-lived, late successional), and that these species trade a higher risk of frost damage for the opportunity of vigorous growth at the beginning of spring, before canopy closure. This information should be considered when assessing the impacts of climate change on vegetation or developing phenological models. |

| Abstract |
To evaluate the potential of soybean as a crop for bio-fuel in Taiwan, field experiments were conducted in 2006 across the island, using an Australian variety ‘Leichardt’. This study was one of the field experiments at Hemei Township, Changhua County. Soybean was seeded by hand-spreading in the fall of 2006 and harvested in 2007. Results showed that seeding of soybean by hand-spreading affected uniformity of seed germination and caused high variations in yield in this field. Seed yield of soybean reached 770 kg ha-1 under good pest management and disease control. The study also showed that night illumination is an important factor affecting growth and yield of soybean. Plants growing near the roadside (within 10–20 m) were exposed to the night light, resulting in prolonged vegetative growth and delayed blossom period for about 1 to 4 weeks. Therefore, such plants suffered from poor pod filling due to low temperature stress at reproduction stage and delayed the harvest period for about 6 weeks. Nevertheless, seed yield of soybean plants exposed to the night illumination reached 1000 kg ha-1, which was slightly higher than soybean plants without exposuring to the night illumination. |
