Somatic embryogenesis of Vitis vinifera L. (cv Sugraone) from stigma and style culture
Somatic embryo and plant regeneration were induced from stigma and style culture of grapevine (Vitis vinifera L. cv. Sugraone). To obtain somatic embryogenesis, explants were cultured on Nitsch and Nitsch basal medium (NN) supplemented with 88 mM sucrose and various combinations of the auxin β-naphthoxyacetic acid (NOA, 0-10 μM) and the cytokinin 6-benzylaminopurine (BA, 0-9 μM). Growth regulators (BA and NOA) in the culture medium were essential for induction of somatic embryogenesis since explants incubated on hormone-free medium never regenerated somatic embryos. Usually, the regenerated somatic embryos become visible as small white globular structures on the surface of the callus 3-4 mo…
Morpho-agronomic and genetic diversity among twelve sicilian agro-ecotypes of lentil (Lens culinaris)
Although Sicily is relatively small (about 25000 km2), it accounts for several agro-ecotypes of lentil (Lens culinaris Medik.), for many of which no data on morphological, agronomic, and organoleptic characteristics are available to date. Thus, experiments were performed to characterize 12 lentil agro-ecotypes from different areas of Sicily, including some small islands surrounding the main island, and to assess the extent of genetic diversity (by means of six inter-simple sequence repeat [ISSR] primers). A famous agro-ecotype from central Italy (Castelluccio di Norcia) and two commercial varieties from Canada (Eston and Laird) were also included in the study. The results showed a large deg…
The seed endophytic microbiota of Citrus limon L. Burm. F
Background Plant seeds possess a complex microbiota which may play a crucial rolein a plethora of mechanisms, such as preservation, germination, seedling development, plant growth and health. In particular, seed endophytic microbiota is gaining more and more consideration due to the fact that it may be vertically transmitted to ensure individual competitive advantages. The Citrusspecies, including C.limon,areone of the most economically important evergreen fruit crops in the world. Objectives i)Identification and characterization ofmicrobial isolates from Citrus limon L. Burm. F. seed endosphere. ii) Structure of Citrus limon L. Burm. F. seed endosphytic microbiota. Methods -Surface-sterili…
