It is known that evolutionarily new genes can rapidly evolve essential roles in fundamental biological processes. Nevertheless, the underlying molecular mechanism of how they acquire theft novel transcriptional pattern is less characterized except for the role ofcis-regulatory evolution. Epigenetic modification offers an alternative possibility. Here, we examined how histone modifications have changed among different gene age groups in Drosophila melanogaster by integrative analyses of an updated new gene dataset and published epigenomic data. We found a robust pattern across various datasets where both the coverage and intensity of active histone modifications, histone 3 lysine 4 trimethylation and lysine 36 trimethylation, increased with evolutionary age. Such a temporal correlation is negative and much weaker for the repressive histone mark, lysine 9 trimethylation, which is expected given its major association with heterochromatin. By further comparison with neighboring old genes, the depletion of active marks of new genes could be only partially explained by the local epigenetic context. All these data are consistent with the observation that older genes bear relatively higher expression levels and suggest that the evolution of histone modifications could be implicated in transcriptional evolution after gene birth.

Non-crop habitats may play a vital role in conservation biological control. This study tested the effect of ryegrass （Lolium multiflorum L.） strips on aphid and la- dybird populations in adjacent winter wheat fields. The field experiment was conducted in three ryegrass-margin wheat plots and three control plots in 2010 in North China. In spring, the same aphid species, Sitobion miscanthi （Takahashi）, was found in both the ryegrass strips and wheat plots. The population density of ladybirds in the ryegrass strips （3.5 4- 0.9/m2） was significantly higher than in the wheat plots （1.5 4- 0.5/m2）. We cut the ryegrass, forcing the ladybirds to migrate to the wheat fields. Three and eight days after cutting the ryegrass, the aphid numbers in the ryegrass-margin wheat plots decreased significantly： they were 19.9% and 53.6%, respectively, lower than in control plots. In the early period of ladybird population development, the percentage of larvae was greater in the ryegrass-margin wheat plots than in controls, and the peak number of pupae in the ryegrass-margin wheat plots occurred 5 days earlier than in the control plots. The results suggest that ryegrass strips may promote the development of ladybird populations. Cutting ryegrass can manipulate ladybirds to enhance biological aphid control in wheat fields. The efficiency of this management approach is discussed.

We analyze the global structure and evolution of human gene coexpression networks driven by new gene integration. When the Pearson correlation coefficient is greater than or equal to 0.5, we find that the coexpression network consists of 334 small components and one "giant" connected subnet comprising of 6317 interacting genes. This network shows the properties of power-law degree distribution and small-world. The average clustering coefficient of younger genes is larger than that of the elderly genes(0.6685 vs. 0.5762). Particularly, we find that the younger genes with a larger degree also show a property of hierarchical architecture. The younger genes play an important role in the overall pivotability of the network and this network contains few redundant duplicate genes. Moreover, we find that gene duplication and orphan genes are two dominant evolutionary forces in shaping this network. Both the duplicate genes and orphan genes develop new links through a "rich-gets-richer"mechanism. With the gradual integration of new genes into the ancestral network, most of the topological structure features of the network would gradually increase. However, the exponent of degree distribution and modularity coefficient of the whole network do not change significantly, which implies that the evolution of coexpression networks maintains the hierarchical and modular structures in human ancestors.

Small RNAs（s RNAs） play essential roles in plants upon biotic stress. Plants utilize RNA silencing machinery to facilitate pathogen-associated molecular pattern-triggered immunity and effector-triggered immunity to defend against pathogen attack or to facilitate defense against insect herbivores. Pathogens, on the other hand, are also able to generate effectors and s RNAs to counter the host immune response. The arms race between plants and pathogens/insect herbivores has triggered the evolution of s RNAs,RNA silencing machinery and pathogen effectors. A great number of studies have been performed to investigate the roles of s RNAs in plant defense, bringing in the opportunity to utilize s RNAs in plant protection. Transgenic plants with pathogen-derived resistance ability or transgenerational defense have been generated, which show promising potential as solutions for pathogen/insect herbivore problems in the field. Here we summarize the recent progress on the function of s RNAs in response to biotic stress, mainly in plant-pathogen/insect herbivore interaction,and the application of s RNAs in disease and insect herbivore control.

The Colorado potato beetle （CPB）, Leptinotarsa decemlineata （Say）, is an infamous invasive species worldwide that aggressively attacks potato and other Solanaceae crops. CPB was first found in China in 1993 and has since spread across 2.77 × 105 km2 in Xinjiang Uygur Autonomous Region. To better understand genetic variation and migration patterns, we used seven polymorphic microsatellite loci to elucidate the genetic relationships and gene flow among 10 CPB populations across Xinjiang. （i） Overall low levels of genetic diversity were detected on the entire population in Xinjiang but most of the diversity was retained among populations during invasion. （ii） The mean pairwise FST was low （0.071 ± 0.043） among populations. The genetic differentiation was little （pairwise FST 0.038 ± 0.016） between the five interior populations （Wusu, Urumqi, Jimsar, Qitai and Mulei） and Tacheng population. The six populations might come from the same genetic group via Bayesian clustering and were closely related on a neighbor-joining tree. Combining the history data, the five interior populations may have originated from Tacheng. （iii） Gene flow was frequent, especially among the five interior populations. Individuals from the interior populations could be assigned to Tacheng at higher probabilities （means 0.518 ± 0.127） than vice versa （means 0.328 ± 0.074）, suggesting that the beetle population has spread from the border to the interior in Xinjiang.
