Project description:We adopted the high-throughput sequencing technology and compared the transcriptomes of Moso bamboo rhizome buds in germination stage and late development stage. We found that the development of Moso bamboo rhizome lateral buds was coordinated by multiple pathways, including meristem development, sugar metabolism and phytohormone signaling. Phytohormones have fundamental impacts on the plant development. We found the evidence of several major hormones participating in the development of Moso bamboo rhizome lateral bud. Furthermore, we showed direct evidence that Gibberellic Acids (GA) signaling participated in the Moso bamboo stem elongation.

Project description:Tibetan chickens exhibit specific adaptations to high-altitude conditions compared with their lowland counterparts. To illustrate the genetic mechanisms of such adaptations in highland chickens, the genomes of four highland and four lowland chicken populations were resequenced. Our results showed that genes under positive selection in highland populations were related to cardiovascular and respiratory system development, DNA repair, response to radiation, inflammation, and immune response, indicating a strong adaptation to oxygen scarcity and high-intensity solar radiation. The distribution of allele frequencies of non-synonymous single nucleotide polymorphisms between highland and lowland populations was also analyzed by chi-square test. The results showed that several differentially distributed genes with missense mutations were enriched in several functional categories, especially in blood vessel development, which were related to adaptations to hypoxia and intense radiation. RNA sequencing also revealed that several differentially expressed genes were enriched in gene ontology terms related to blood vessel and respiratory system development. Additionally, an evident admixture found in Tibetan chickens suggested a history of introgression from lowland gene pools. Overall, our data provided new insights into the unique adaptation of highland animals to extreme environments.
