Phosphoribulokinase （PRK）, a nuclear-encoded plastid-localized enzyme unique to the photosynthetic carbon reduction （Calvin） cycle, was cloned and characterized from the stramenopile alga Vaucheria litorea. This alga is the source of plastids for the mollusc （sea slug） Elysia chlorotica which enable the animal to survive for months solely by photoautotrophic CO2 fixation. The 1633-bp V. litorea prk gene was cloned and the coding region, found to be interrupted by four introns, encodes a 405-amino acid protein. This protein contains the typical bipartite target sequence expected of nuclearencoded proteins that are directed to complex （i.e. four membrane-bound） algal plastids. De novo synthesis of PRK and enzyme activity were detected in E. chlorotica in spite of having been starved of V. litorea for several months. Unlike the algal enzyme, PRK in the sea slug did not exhibit redox regulation. Two copies of partial PRK-encoding genes were isolated from both sea slug and aposymbiotic sea slug egg DnA using PCR. Each copy contains the nucleotide region spanning exon 1 and part of exon 2 of V litorea prk, including the bipartite targeting peptide. However, the larger prk fragment also includes intron 1. The exon and intron sequences of prk in E. chlorotica and V/itorea are nearly identical. These data suggest that PRK is differentially regulated in V. litorea and E. chlorotica and at least a portion of the V. litorea nuclear PRK gene is present in sea slugs that have been starved for several months.

Reproductive patterns in Araucaria araucana forests in the Andean range, Chile

Ecological Processes 2024年第1期13卷 252-261页

Background Araucaria araucana is a mast species that presents a high variability in annual cone production. Researchers have recorded synchronization events in cone production in different populations, which allows the seed production to be concentrated, reducing the percentage of seeds consumed by different animal *** We sampled three populations located in the Andes Mountains, Araucanía Region, Chile. In 2004 we began the collection of data on cone production, for which we installed permanent plots（1200 m2each） at each location. We identified and labeled each female tree in each plot to monitor its cone production. In 2012 we selected a total of 30 trees near the plots to evaluate the number of seeds per cone. In each February from 2012 to 2014 we selected two mature cones and covered them with a porous mesh for subsequent collection and storage in March. At the beginning of June, we counted and weighed the seeds, determining the average weight, the number of seeds per cone, the germination capacity（GC）, and the germination speed（GS）.Results Cone production was synchronous across the three locations. We observed significant differences among the locations and years evaluated. The cones had fewer seeds in 2013（high production） compared to those in 2012（low production）, but their weights were similar. In 2014 the cones produced smaller seeds in fewer quantities. The difference between the years 2013 and 2014 resulted from the high-energy expenditure in 2013. Regarding GC and GS, there were significant differences among the three locations（GC: F = 45.41, p n *** Both GC and GS are related to seed weight but not to the number of cones produced in a given year. These annual fluctuations in seed production are determining factors in the population dynamics of forest species. Our results allow a better understanding of the reproductive phenology of A. araucana and could hel

给小儿的每张药物处方,都应注意药物可能出现营养方面的副作用。当发生营养紊乱时,对给药前的可能病因则易被忽略。了解药物对小儿营养的影响,这是临床治疗学中极为重要的问题。药物所致营养方面的副作用,可归纳四个方面:抑制或增进食欲,影响营养素的吸收,妨碍营养素的代谢和利用,以及改变营养素的排泌。一些常用药物影响营养的情况见下表。

Globally,sub-optimal use of nitrogen (n) fertiliser and elevated n irrigation groundwater have led to high leached nitrate (nO_(3)^(–)) losses from protected vegetable field *** fertiliser and irrigation management in different soil types is crucial to reduce future n loads from such *** present 4-year study examined leached n loads from lysimeter monitoring arrays set up across 18 protected vegetable system sites encompassing the dominant soil types of northern *** treatments applied at each field site were:1) a high n and high irrigation input treatment (HnHI);2) a low n but high irrigation input treatment (LnHI) and 3) a low n with low irrigation input treatment (LnLI).Results showed that the mean annual leached total nitrogen loads from the HnHI,LnHI and LnLI treatments were 325,294 and 257 kg n ha^(–1) in the fluvo-aquic soil,114,100 and 78 kg n ha^(–1) in the cinnamon soil and 79,68 and 57 kg n ha^(–1) in the black soil,*** n dissolved in irrigation water in the fluvo-aquic soil areas was 8.26-fold higher than in the cinnamon areas.A structural equation model showed that n fertiliser inputs and leaching water amounts explained 14.7 and 81.8%of the variation of leached n loads,***,reducing irrigation water by 21.5%decreased leached n loads by 20.9%,while reducing manure n and chemical n inputs by 22 and 25%decreased leached n loads by only 9.5%. This study highlights that protected vegetable fields dominated by fluvo-aquic soil need management to curtail leached n losses in northern China.
