AB  - Eruca sativa is known in traditional medicine for its therapeutic effects, while young plants
are used as a salad or green food. Recently, the consumption of rocket has increased considerably,
so it has become very important for breeders. Plant tissue culture provides a platform to overcome
the problems in improving this species. In the present study, an efficient protocol for in vitro shoot
regeneration and propagation of recalcitrant rocket variety Domaća rukola was studied. Murashige
and Skoog (MS, 1962) medium containing 0.1 mg/L BA and frequent subculture over a period
of three weeks proved to be optimal for shoot multiplication with a multiplication index of over 3
and only 8.72% of hyperhydrated shoots without necrosis. Different concentrations of 2,4-D, BA, or
TDZ in combination with NAA, with or without the presence of AgNO3, were tested for de novo
shoot organogenesis (DNSO) from seedling explants. The hypocotyl explants cultured on MS with a
combination of TDZ1.0+NAA0.1+AgNO3 5.0 mg/L regenerated viable shoots with the highest rate
(25.38%) and an average number of 2.18 shoots per regenerating explant. Somatic embryogenesis
from immature zygotic embryos proved to be the best way to regenerate a recalcitrant rocket cultivar.
The highest embryogenic efficiency was achieved in explants cultured on MS medium containing
1.0 mg/L 2,4-D with a frequency of 76.64% and 5.13 mean number of regenerated somatic embryos
per explant, which were further converted into normal plants. Additionally, in vitro-produced rocket
shoots could serve as a possible promising source for the production of flavonoid kaempferol with
proven antioxidant properties.

AB  - Eruca sativa (rocket, Brassicaceae), is known in traditional medicine for its therapeutic, while young plants are used as salad, vegetable, or green foods. Genetic improvement of the rocket has been limited due to the appearance of biennial plants and the requirement for isolation barriers. Plant tissue culture offers a platform to overcome existing barriers to improving this species. The present study aimed to achieve a feasible protocol for shoot regeneration and propagation of rocket cv. Domaća rukola and to evaluate the use of AgNO3 to improve regeneration efficiency. Proliferation of shoots from seedling epicotyl, shoot organogenesis from root, hypocotyl and cotyledon seedling explants, and somatic embryogenesis from immature zygotic embryos were studied. Murashige and Skoog (MS) basal medium in combination with a low KIN concentration of 0.1 mg l-1 with frequent subculture over a period of 3 weeks was found to be optimal for shoot multiplication with a multiplication index of almost 3 and only 9.3% of vitrified shoots without necrosis. Different concentrations of 2,4-D, BA or TDZ in combination with NAA and with or without AgNO3 were tested for shoot regeneration from seedling explants. As a result, the hypocotyl explants cultured on MS with a combination of TDZ 1.0+NAA 0.1+AgNO3 5.0 mg l-1 provided healthy shoots with a satisfactory regeneration rate of 25.4% and 2.2 mean number of shoots per regenerating explant. Immature zygotic embryos cultured on MS medium containing 1.0 mg l-1 2.4-D showed the highest regeneration frequency (78.76%) as well as the number of regenerated somatic embryos per explant (5.13) with low incidence of callusing and necrosis. KIN at 0.5 mg l-1 enabled the best conversion of somatic embryos into healthy plants (22.5%). The results provide an opportunity to use established regeneration protocols in rocket breeding improvement programs.
