Comparative transcriptome analysis reveals differential gene expression in sterile and fertile rubber tree varieties during flower bud differentiation.

Plant male sterility (MS) is an important agronomic trait that provides an efficient tool for hybridization and heterosis utilization of crops. Based on phenotypic and cytological observations, our study performed a multi-comparison transcriptome analysis strategy on multiple sterile and fertile rubber tree varieties using RNA-seq. Compared with the male-fertile varieties, a total of 1590 differentially expressed genes (DEGs) were detected in male-sterile varieties, including 970 up-regulated and 620 down-regulated transcripts in sterile varieties.

The rubber tree genome reveals new insights into rubber production and species adaptation.

The Para rubber tree (Hevea brasiliensis) is an economically important tropical tree species that produces natural rubber, an essential industrial raw material. Here we present a high-quality genome assembly of this species (1.37 Gb, scaffold N50 = 1.

[Research progress of preparation and application of specific DNA probes from plant].

In this paper, the types of specific DNA probes from plant were briefly described,and some methods of constructing specific probes were introduced,mainly were the isolation and screening of specific DNA sequences. The applications of the specific probes in the germplasm and foreign chromosome identifications, the karyotype and genome analyses were also summarized and discussed.

[Studies on bilingual teaching of genetics].

Bilingual teaching of genetics is a new teaching research area. This paper introduces a number of texts of genetics in English, and outlines principles of bilingual teaching of genetics.
