    Notes: Abstract Five genotypes of chickpea (Cicer arietinum L.) PG1, PG5, PG12, N59 and C235 were evaluated for induction of somatic embryogenesis. Somatic embryogenesis was induced from immature cotyledons of genotypes PG12 and C235 and immature embryo axes of genotypes PG5, PG12 and C235. Genotypes N59 and PG1 showed no response. The maximum frequency of globular embryo formation occurred in cotyledonary segments on MS medium with 3.0 mg/l 2,4,5-trichlorophenoxyacetic acid (2,4,5-T). Further embryo development was achieved only in somatic embryos derived from cotyledonary segments of genotype PG12. Globular-stage embryos derived from immature embryo axes of PG5, C235, PG12, and cotyledonary segments of C235 dedifferentiated and formed callus. The cotyledonary stage embryos of genotype PG12 germinated on half-strength MS medium supplemented with 1 mg/l zeatin. The regenerated plants were transferred to soil and grown to maturity.

    Notes: Abstract  Embryo axes of four accessions of chickpea (Cicer arietinum L.) were treated with Agrobacterium tumefaciens strains C58C1/GV2260 carrying the plasmid p35SGUSINT and EHA101 harbouring the plasmid pIBGUS. In both vectors the GUS gene is interrupted by an intron. After inoculation shoot formation was promoted on MS medium containing 0.5 mg/l BAP under a selection pressure of 100 mg/l kanamycin or 10 mg/l phosphinothricin, depending on the construct used for transformation. Expression of the chimeric GUS gene was confirmed by histochemical localization of GUS activity in regenerated shoots. Resistant shoots were grafted onto 5-day-old dark-grown seedlings, and mature plants could be recovered. T-DNA integration was confirmed by Southern analysis by random selection of putative transformants. The analysis of 4 plantlets of the T1 progeny revealed that none of them was GUS-positive, whereas the presence of the nptII gene could be detected by polymerase chain reaction.
