Development of a genetic marker linked to a new thermo-sensitive male sterile gene in rice (Oryza sativa L.)
Application of the thermo-sensitive genic male sterile (TGMS) system has a great potential to increase the efficiency of hybrid rice breeding and the gene from 0A15-1 is a new TGMS gene and tentatively designated tms6(t).

This is the first report about a disease resistant mutation obtained successfully in rice by tissue culture and in vitro screening with phytotoxin.
Selection of brown spot‐resistant rice plants from Helminthosporium oryzae toxin‐resistant calluses
Four toxin-resistant calluses were selected and plants regenerated from two of these resistant calluses showed resistance to the pathogen, heritable and stability of resistance was observed in the R1, R2 and R3 generations.
Somatic embryogenesis and plant regeneration in an interspecific hybrid of Oryza
Various developmental stage of embryoid, such as globular, heart-shape, scutellum-shape and mature embryoid were observed in an embryogenic callus.
High-frequency somatic embryogenesis from small suspension-cultured clusters of cells of an interspecific hybrid of Oryza
Suspension cultures in which cell clusters were small and had a high capacity for somatic embryogenesis were established from immature panicles of F1 plants from a cross between Oryza sativa and Oryze latifolia, useful for biochemical and molecular biological research of the somatic embryos in the Gramineae.
Direct development of plantlets from immature panicles of rice in vitro
It is suggested that spikelet budding occurs by the reversion of floral primordia to vegetative stage or by the formation of adventitious buds from epidermal cells.

Male sterile mutant from somatic cell culture of rice
This is the first paper to report male-steriles in regenerated plants and their offspring obtained from somatic cell culture, showing that the male- Sterile was controlled by two independent nuclear genes.
FISH analysis of the integration patterns in transgenic rice co-transformed by microprojectile bombardment
Using multi-color fluorescencein situ hybridization (FISH), we localized transferredbarnase-ps1 andpHctinG DNA sequences onto chromosomes of two transgenic rice plants, named Q12 and Q13, both of…
