    "Hoshiminori", which is a new rice cultivar with early maturing and good eating quality, was bred by the Institute of Crop Science, NARO (NICS) in 2015. This cultivar was selected from a population derived from the cross between "Kanto 209(Satojiman)" and "Etsunan 171" conducted in 2002. The main characteristics as follows; The heading and maturing dates of "Hoshiminori" are slightly earlier than those of "Asanohikari". The maturity is classified into "moderately early" in the Kanto region. The culm and panicle lengths are longer than "Asanohikari", however, the number of panicles per area is less than that of "Asanohikari". The yield of brown rice is 19% higher than "Asanohikari" in the late-transplanting yield trial tests of NICS. Its eating quality of cooked rice is equivalent to that of "Koshihikari" and is classified into "excellent". "Hoshiminori" harbors the Stvb-i gene, therefore, shows resistance to the rice stripe virus. "Hoshiminori" is expected to be suitable for late-transplanting in rice-wheat/barley double cropping areas such as the northern Kanto area.

    <title>Abstract</title>
    Loss of seed shattering has been regarded as a key step during crop domestication. Mutagenesis contributes to the development of novel crop cultivars with a desired seed-shattering habit in a relatively short period of time, but also to uncovering the genetic architecture of seed shattering. ‘Minamiyutaka’, a non-shattering <italic>indica</italic> rice cultivar, was developed from the easy-shattering cultivar ‘Moretsu’ by mutation breeding via gamma-ray irradiation. In present study, we observed significant differences in shattering habit, breaking tensile strength, and abscission zone structure between ‘Moretsu’ and ‘Minamiyutaka’. Whole-genome mutation analysis of ‘Minamiyutaka’ newly identified a 13-bp deletion causing defective splicing in exon 3 of the <italic>OsSh1</italic> gene which has previously been referred to as a candidate for controlling seed shattering. Using CRISPR/Cas9 gene editing, we demonstrated that loss-of-function mutation in <italic>OsSh1</italic> causes non-shattering in rice. Furthermore, gene expression analysis suggests that <italic>OsSh1</italic> may function downstream of <italic>qSH1</italic>, a known key gene involved in abscission zone differentiation<italic>.</italic> Nucleotide diversity analysis of <italic>OsSh1</italic> in wild rice accessions and cultivars revealed that <italic>OsSh1</italic> has been under strong selection during rice domestication, and a missense mutation might have contributed to the reduction of seed shattering from the wild progenitors to cultivated rice.

    We have succeeded in selecting four higher yield mutants from five gamma-ray irradiated high-yielding Japanese rice varieties using a novel approach. A total of 464 M2 plants which had heavier total panicle weights per plant were first selected from 9801 irradiated M2 plants. Their higher yields were confirmed by yield trials conducted for three years with a six to ten-pairwise replicated plot design. FukuhibikiH6 and FukuhibikiH8 were selected from an irradiated high-yielding variety Fukuhibiki and showed 1.2% to 22.5% higher yield than their original significantly. YamadawaraH3 was selected from an irradiated high-yielding variety Yamadawara and its yield advantages were 2.7% to 3.9%. However, there was no difference in the genotypes of the 96 SNP (single nucleotide polymorphism) markers between the higher yield mutants and their respective original varieties. The differences in the measured phenotypical traits between each mutant and its original variety were not constant and the actual differences were marginal. Therefore, the higher yields of the selected mutants were likely to have been caused by physiological traits rather than phenotypical traits. The selection method used in this study is an application of the directed evolution method which has long been commonly used in the substantial improvements of microorganisms and their proteins.

    <title>Abstract</title>Ion beams are physical mutagens used for plant and microbe breeding that cause mutations via a distinct mechanism from those of chemical mutagens or gamma rays. We utilized whole-exome sequencing of rice DNA in order to understand the properties of ion beam-induced mutations in a genome-wide manner. DNA libraries were constructed from selected carbon-ion-beam-induced rice mutants by capturing with a custom probes covering 66.3 M bases of nearly all exons and miRNAs predicted in the genome. A total of 56 mutations, including 24 single nucleotide variations, 23 deletions, and 5 insertions, were detected in five mutant rice lines (two dwarf and three early-heading-date mutants). The mutations were distributed among all 12 chromosomes, and the average mutation frequency in the M1 generation was estimated to be 2.7 × 10-7 per base. Many single base insertions and deletions were associated with homopolymeric repeats, whereas larger deletions up to seven base pairs were observed at polynucleotide repeats in the DNA sequences of the mutation sites. Of the 56 mutations, six were classified as high-impact mutations that caused a frame shift or loss of exons. A gene that was functionally related to the phenotype of the mutant was disrupted by a high-impact mutation in four of the five lines tested, suggesting that whole-exome sequencing of ion-beam-irradiated mutants could facilitate the detection of candidate genes responsible for the mutant phenotypes.

    The genetic variation of rice cultivars provides a resource for further varietal improvement through breeding. Some rice varieties are sensitive to benzobicyclon (BBC), a β-triketone herbicide that inhibits 4-hydroxyphenylpyruvate dioxygenase (HPPD). Here we identify a rice gene, HIS1 (HPPD INHIBITOR SENSITIVE 1), that confers resistance to BBC and other β-triketone herbicides. We show that HIS1 encodes an Fe(II)/2-oxoglutarate-dependent oxygenase that detoxifies β-triketone herbicides by catalyzing their hydroxylation. Genealogy analysis revealed that BBC-sensitive rice variants inherited a dysfunctional his1 allele from an indica rice variety. Forced expression of HIS1 in Arabidopsis conferred resistance not only to BBC but also to four additional β-triketone herbicides. HIS1 may prove useful for breeding herbicide-resistant crops.
