5-氮胞苷和利福平对丛枝病泡桐幼苗形态和蛋白质变化的协同影响

以感染丛枝病的豫杂一号泡桐幼苗为试验材料,通过不同浓度5-氮胞苷和利福平处理,研究了其幼苗形态和蛋白质的变化。结果表明,适宜浓度的利福平和5-氮胞苷共同使用可抑制泡桐丛枝病的发生。150μmol·L-15-氮胞苷+80 mg·L-1利福平可以抑制豫杂一号泡桐丛枝病症状。存在于健康豫杂一号幼苗中的蛋白质pI 6.8、m24ku而在病苗中观察不到。表明该蛋白质可能与豫杂一号泡桐丛枝病发生有一定关系。

Embryonic adaptations and nutrition in the viviparous teleost Clinus dorsalis (Perciformes: Clinidae)

Embryos of Clinus dorsalis absorb nutrients from the embiyotrophe, secreted by the follicular epithelium. Autoradiographic studies revealed that the principal areas of nutrient absorption are the embryonic gut and epidermis. A histological and electron microscopic study of embryonic structure revealed an extensively hypertrophied gut with numerous flngerlike villi projecting into the gut lumen. A brushborder of microvilli is, furthermore, characteristic of the columnar gut epithelium. Epidermal surface area is increased apically on individual epidermal cells, particularly on the ventral pericardial surface. Micro ridges further increase epidermal surface area. Epidermal surface area is reduced and a mucous layer is secreted prior to parturition.

Growth-dependent survival mechanisms during the early life of a temperate seabass (Lateolabrax japonicus): field test of the ‘growth–mortality’ hypothesis

Three concepts based on size, time and growth rate are contained in the functional mechanisms of the ‘growth–mortality’ hypothesis, and are known as the ‘bigger is better’, ‘stage duration’ and ‘growth-selective predation’ hypotheses, respectively. Although it is sufficiently documented in fishes that faster growing and bigger larvae selectively survive, synergistic operation of the three components of the ‘growth–mortality’ hypothesis within a species have received little attention. In this study, we have tested the components of the ‘growth–mortality’ hypothesis based on the growth characteristics of original population (OP) and survivors (SV) of Japanese seabass (JSB) Lateolabrax japonicus. Larval and juvenile JSB were repeatedly sampled from the Tango Sea in 2007 and 2008. Otoliths from larvae and juveniles were analyzed to produce back-calculated daily records of size-at-age and growth rate, and were compared between OP and SV. Selective survival for fast-growing and bigger larvae was evident, and our results strongly support the ‘bigger is better’ hypothesis as well as the ‘growth-selective predation’ hypothesis. Growth rates of the individuals that metamorphosed into juveniles had significantly faster growth rates than non-metamorphosing larvae older than 48 days, the minimum age for metamorphosis, suggesting a clear relationship between growth rates and the timing of metamorphosis. On average, SV completed the larval stage ∼13 days earlier than those of OP, supporting the ‘stage duration’ hypothesis. Thus, SV of JSB exhibited traits consistent with all aspects of the ‘growth–mortality’ hypothesis: faster growth, bigger size-at-age, and shorter larval stage duration (LSD), i.e., larvae with faster growth, bigger size-at-age and a shorter LSD selectively survived the larval period. Although maternal influence on growth and survival was evident, factors that regulate growth–mortality mechanisms remain to be explored for JSB.
