Flowering represents a pivotal developmental transition from the vegetative stage to the reproductive stage. The timing of flower- ing must be carefully controlled under ever-changing environ- mental conditions to ensure successful reproduction. Extensive genetic and molecular biological analyses in the model species Arabidopsis thaliana have identified important regulators of flowering time and revealed a complex network of highly inter- connected pathways that are regulated by seasonal cues （e.g., light and temperature） and internal factors （e.g., age and nutrient availability）（Bouche et al., 2016）.

APOPTOSIS or programmed cell death is a model of cell death, along with typical morphological and biochemical changes. The cell death, occurring during embryonic development, T and B cell maturation and endocrine-induced atrophy, is a physiological apoptosis which controls the amount of cells in the body. Apoptosis can also be induced by various factors, such as ionizing radiation and anti-tumour agents which damage DNA, and has been proposed to be a consequence of the induced expression of some tumour-related genes or increase of the proteins sta-

The drought-escape response accelerates flowering in response to drought stress, allowing plants to adaptively shorten their life cycles. Abscisic acid (ABA) mediates plant responses to drought, but the role of ABA-responsive element (ABRE)-binding factors (ABFs) in the drought-escape response is poorly understood. Here, we show that Arabidopsis thaliana ABF3 and ABF4 regulate flowering in response to drought through transcriptional regulation of the floral integrator SUPPRESSOR OF OVEREXPRESSION OF CONSTANS1 (SOC1). The abf3 abf4 mutant displayed ABA-insensitive late flowering under long-day conditions. Ectopic expression of ABF3 or ABF4 in the vasculature, but not in the shoot apex, induced early flowering, whereas expression of ABF3 fused with the SRDX transcript!onal repressor domain delayed flowering. We identified SOC1 as a direct downstream target of ABF3/4, and found that SOC1 mRNA levels were lower in abf3 abf4 than in wild-type plants. Moreover, induction of SOC1 by ABA was hampered in abf3 abf4 mutants. ABF3 and ABF4 were enriched at the -1028- to -657-bp region of the SOC1 promoter, which does not contain canonical ABF-ABRE-binding motifs but has the NF-Y binding element. We found that ABF3 and ABF4 interact with nuclear factor Y subunit C (NF-YC) 3/4/9 in vitro and in planta, and induction of SOC1 by ABA was hampered in nf-yc3 yc4 yc9 mutants. Interestingly, the abf3 abf4, nf-yc3 yc4 yc9, and sod mutants displayed a reduced drought-escape response. Taken together, these results suggest that ABF3 and ABF4 act with NF-YCs to promote flowering by inducing SOC1 transcription under drought conditions . This mechanism might contribute to adaptation by enabling plants to complete their life cycles under drought stress.

对分离自巴布亚新几内亚地热活跃区的一种嗜热耐酸古细菌——JP2菌株中的DNA连接酶基因进行了克隆、表达、纯化,并对其生物化学及酶学特性进行了研究.对其核酸及氨基酸序列的分析表明:JP2菌株的DNA连接酶与古细菌种Sulfolobussolfataricus和Sulfolobusshibatae的DNA连接酶具有很高的同源性,尤其在与功能紧密相关的6个保守结构基序的一致性更高.JP2连接酶表现出高的DNA缺口连接活性,在二价金属辅因子的选择方面,JP2连接酶更倾向于Mn2+离子而不是Mg2+、Ca2+及其他离子.不同温度时的热稳定性测试显示:JP2连接酶在50～80℃时为较适连接温度,当温度不超过85℃时,连接酶的活性在5h内保持相对稳定,但在90℃以上活性则很快降低.还分离纯化了JP2的分子伴侣——TF55,并将其应用于增加JP2连接酶的热稳定性研究.结果表明:在体外85℃时,分子伴侣未增加连接酶的热稳定性,可能的原因是在85℃体外状态下TF55本身就表现出不稳定性.

This paper reviews gravitational wave sources and their detection. One of the most exciting potential sources of gravitational waves are coalescing binary black hole systems. They can occur on all mass scales and be formed in numerous ways, many of which are not understood. They are generally invisible in electromagnetic waves, and they provide opportunities for deep investigation of Einstein's general theory of relativity. Sect. 1 of this paper considers ways that binary black holes can be created in the universe, and includes the prediction that binary black hole coalescence events are likely to be the first gravitational wave sources to be detected. The next parts of this paper address the detection of chirp waveforms from coalescence events in noisy *** analysis is computationally intensive. Sect. 2 reviews a new and powerful method of signal detection based on the GPUimplemented summed parallel infinite impulse response filters. Such filters are intrinsically real time alorithms, that can be used to rapidly detect and localise signals. Sect. 3 of the paper reviews the use of GPU processors for rapid searching for gravitational wave bursts that can arise from black hole births and coalescences. In sect. 4 the use of GPU processors to enable fast efficient statistical significance testing of gravitational wave event candidates is reviewed. Sect. 5 of this paper addresses the method of multimessenger astronomy where the discovery of electromagnetic counterparts of gravitational wave events can be used to identify sources, understand their nature and obtain much greater science outcomes from each identified event.
