Epidermal growth factor receptor (EGFR) is involved in multiple aspects of cancer cell biology. EGFR has already been identified as an important target for cancer therapy, with various kinds of EGFR...

Development in Rice Genome Research Based on Accurate Genome Sequence

Matsumoto, Takashi, Wu, Jianzhong, Antonio, Baltazar A., Sasaki, Takuji

Rice is one of the most important crops in the world. Although genetic improvement is a key technology for the acceleration of rice breeding, a lack of genome information had restricted efforts in...

Barley grain with adhering hulls is controlled by an ERF family transcription factor gene regulating a lipid biosynthesis pathway

Taketa, Shin, Amano, Satoko, Tsujino, Yasuhiro, Sato, Tomohiko, Saisho, Daisuke, Kakeda, Katsuyuki, ...

In contrast to other cereals, typical barley cultivars have caryopses with adhering hulls at maturity, known as covered (hulled) barley. However, a few barley cultivars are a free-threshing variant...

A Single Banana Streak Virus Integration Event in the Banana Genome as the Origin of Infectious Endogenous Pararetrovirus▿

Gayral, Philippe, Noa-Carrazana, Juan-Carlos, Lescot, Magali, Lheureux, Fabrice, Lockhart, Benham E. L., Matsumoto, Takashi, ...

Sequencing of plant nuclear genomes reveals the widespread presence of integrated viral sequences known as endogenous pararetroviruses (EPRVs). Banana is one of the three plant species known to...

Two Adjacent Nucleotide-Binding Site–Leucine-Rich Repeat Class Genes Are Required to Confer Pikm-Specific Rice Blast Resistance

Ashikawa, Ikuo, Hayashi, Nagao, Yamane, Hiroko, Kanamori, Hiroyuki, Wu, Jianzhong, Matsumoto, Takashi, ...

The rice blast resistance gene Pikm was cloned by a map-based cloning strategy. High-resolution genetic mapping and sequencing of the gene region in the Pikm-containing cultivar Tsuyuake narrowed...

Analysis of Intraspecies Diversity in Wheat and Barley Genomes Identifies Breakpoints of Ancient Haplotypes and Provides Insight into the Structure of Diploid and Hexaploid Triticeae Gene Pools1[OA]

Wicker, Thomas, Krattinger, Simon G., Lagudah, Evans S., Komatsuda, Takao, Pourkheirandish, Mohammad, Matsumoto, Takashi, ...

A large number of wheat (Triticum aestivum) and barley (Hordeum vulgare) varieties have evolved in agricultural ecosystems since domestication. Because of the large, repetitive genomes of these...

Development of Genome-wide Simple Sequence Repeat Markers Using Whole-genome Shotgun Sequences of Sorghum (Sorghum bicolor (L.) Moench)

Yonemaru, Jun-ichi, Ando, Tsuyu, Mizubayashi, Tatsumi, Kasuga, Shigemitsu, Matsumoto, Takashi, Yano, Masahiro

Simple sequence repeat (SSR) markers with a high degree of polymorphism contribute to the molecular dissection of agriculturally important traits in sorghum (Sorghum bicolor (L.) Moench). We designed...

Evolutionary History of GS3, a Gene Conferring Grain Length in Rice

Takano-Kai, Noriko, Jiang, Hui, Kubo, Takahiko, Sweeney, Megan, Matsumoto, Takashi, Kanamori, Hiroyuki, ...

Unlike maize and wheat, where artificial selection is associated with an almost uniform increase in seed or grain size, domesticated rice exhibits dramatic phenotypic diversity for grain size and...
