(Submitter supplied) The main objective of this study was to analyze the general midgut transcript profile of Schiustocerca gregaria as well as changes in midgut gene expression during different stages of feeding. We compared three different time points of the digestive process: no active digestion (24 h after feeding), the initial stages of feeding (10 min after feeding) and active digestion in the midgut (2 h after feeding).

(Submitter supplied) a high-throughput Illumina/Solexa sequencing was conducted, 478262, 702593, 835394 and 894277 unique sRNAs was discovered from four periods of M. robertsii infection, uninfected (0h), infected for 12h, 24h and 36h. Then, 7, 7, 6 and 7 known pre-miRNAs were obtained, and 33, 58, 54 and 52 candidate novel miRNAs was detected in four periods. Further analysis showed that 24 of those candidate novel miRNAs were matched to other known insect miRNAs, while 36 of those miRNAs lacked sequence homologues of insect organisms.

(Submitter supplied) The human transcription factor (TF) CGGBP1 (“CGG Binding Protein”) is conserved only in amniotes, and is believed to derive from the zf-BED and Hermes transposase DNA-binding domains (DBDs) of a hAT DNA transposon. Here, we examine the DNA binding preferences of a wide variety of metazoan CGGBP1-like TFs with this bipartite domain using PBM experiments. The derived motifs are available at ...

(Submitter supplied) RNA-seq was used to study the genes expressed in peculiar glandular organs that transiently appear in insect embryos and are called the pleuropodia. The locust Schistocerca gregaria (Orthoptera) was used as a model. The purpose of the study is to identify the function of these organs. Our results suport the hypothesis (Slifer, 1937) that the pleuropodia secrete enzymes that digest the serosal cuticle before hatching. more...

(Submitter supplied) The migratory locust, Locusta migratoria, is a serious agricultural pest and important insect model to study insect digestion and feeding behavior. The gut is one of the primary interfaces between the insect and its environment. Nevertheless, knowledge on the gut transcriptome of L. migratoria is still very limited. With the development of two EST databases from L. migratoria (whole body and central nervous system (CNS)) and one EST database from Schistocerca gregaria (CNS), an abundance of transcript data was made available for locusts. more...

(Submitter supplied) Protease inhibitors (PIs) are among the most ubiquitous plant defences against herbivorous insects. These inhibitors arrest proteolytic digestion by binding to the proteases in the gut. However, many pest insects have coevolved mechanisms to counteract these effects. While the nature of these counter-defensive strategies has been well described for several insect pests, our understanding of how these responses are triggered and regulated remains limited. more...

(Submitter supplied) Background: Responses to hypoxia have been investigated in many species; however, comparative study between conspecific geographical populations in different altitude regions is rare, especially for invertebrates . The migratory locust, Locusta migratoria, is widely distributed both on high-altitude Tibetan Plateau (TP) and on low-altitude North China Plain (NP). TP locusts have inhabited Tibetan Plateau since Quaternary glaciations events and thus probably have evolved superior capacity to deal with hypoxia. more...

(Submitter supplied) DNA methylation is a widely conserved epigenetic modification that is established and maintained by the cooperative activity of DNA methyltransferases. While the complement of DNA methyltransferase genes can vary substantially between animal species, whole-genome methylation analyses have suggested that major features of animal methylomes are widely conserved. We have now used genome-scale bisulfite sequencing to analyze the methylome of the desert locust, Schistocerca gregaria, which represents an economically important pest with a high degree of phenotypic plasticity. more...

(Submitter supplied) Background: Hypoxia can affect aerobic organisms profoundly. Biological responses to extreme hypoxia have been well studied. However, it is not well characterized how living organisms respond to mild hypoxia, and how they distinguish different levels of hypoxia. Results: We examined the transcriptional responses of locusts using microarrays to reveal their strategies to cope with mild hypoxia. Mitochondrial activities were systemically suppressed, mainly involving energy production and mitochondrial biogenesis. more...

(Submitter supplied) Desert locusts (Schistocerca gregaria) show an extreme form of phenotypic plasticity and can transform between a cryptic solitarious phase and a swarming gregarious phase. The two phases differ extensively in behavior, morphology and physiology but very little is known about the molecular basis of these differences. We used our recently generated Expressed Sequence Tag (EST) database derived from S. more...

(Submitter supplied) We report the application of single-molecule-based sequencing technology for high-throughput profiling of nervous system in locust Locusta migratoria manilensis. By obtaining over 57,000,000 bases of sequence from central nervous system, we generated 101836 contigs and 69440 scaffolds. We finally get 41179 unigene with an average length of 570bp. There are 5519 unigenes beyond the length of 1000bp. Using BLAST searches of the NR, NT, Swiss-Prot, KEGG and COG databases we are able to identify 13552 unigene (E<0.0001). Comprehensive assessment of all the unigenes by comparing with the studied genes of other insects nervous system reveals that our unigene are broadly representative of the transcriptome of insect nervous system. Our data provides the most large-scale EST-project for locust nervous system, which greatly benefits the exploring of this insect. In addition, we identify a large number of novel nervous genes which can be used in systematic studies of locust and other insects.

However, small RNAs of hemimetabolous insects have not yet been investigated.Study of hemimetabolous insect small RNAs could provide more insights into evolution and function of small RNAs in hemi- and holometabolous insects. The locust is an important, economically harmful hemimetabolous insect and its phase changes is an interesting phenomenon.Here, we used high-throughput sequencing to characterize and compare the small RNA transcriptomes of gregarious and solitary phases in locusts. more...
