Cím:	Santalum molecular biology: molecular markers for genetic diversity, phylogenetics and taxonomy, and genetic transformation / Jaime A. Teixeira da Silva, Mafatlal M. Kher, Deepak Soner, M. Nataraj, Judit Dobránszki, Melissa A. Millar

Megjegyzések:	Species of the Santalum genus are well known for their fragrant hardwood, which has great value in medicinal, pharmaceutical and cosmetic industries. Sandalwood oil is derived from the heartwood of Santalum sp. and contains alpha-, beta- and epi-beta-santalols, which are responsible for its pleasant fragrance. Oil content can vary from species to species. Pressure on natural populations due to habitat loss, legal and illegal harvesting and disease is increasing. This paper highlights the development of molecular markers for the refinement of phylogenetic studies, identification of various Santalum and adulterant species, assessment of genetic diversity, genetic differentiation, clonality and management units within species, and for marker-assisted breeding. The identification of quantitative trait loci for sandal spike disease and for other traits such as specific rare secondary metabolites in the essential oil and related to its fragrance, would also benefit from molecular advances. RNA sequence analyses have already identified changes in gene expression and metabolic pathways in developing Santalum album L. haustoria.

Megjegyzések:	Shoot tip necrosis is a physiological condition and disorder that can arise in plantlets or shoots in vitro that results in death of the shoot tip. This condition, which can spread basipetally and affect the emergence of axillary shoots from buds lower down the stem, is due to the cessation of apical dominance. STN can occur at both shoot multiplication and rooting stages. One of the most common factors that cause STN is nutrient deficiency or imbalance. Moreover, the presence or absence of plant growth regulators (auxins or cytokinins) at specific developmental stages may impact STN. The cytokinin to auxin ratio within an in vitro plant can be modified by varying the concentration of cytokinins used in the culture medium. The supply of nutrients to in vitro shoots or plantlets might also affect their hormonal balance, thus modifying the occurrence of STN. High relative humidity within culture vessels and hyperhydricity are associated with STN. An adequate supply of calcium as the divalent cation (Ca2+) can hinder STN by inhibiting the accumulation of phenolic compounds and thus programmed cell death. Moreover, the level of Ca2+ affects auxin transport and ethylene production, and higher ethylene production, which can occur as a result of high relative humidity in or poor ventilation of the in vitro culture vessel, induces STN. High relative humidity can decrease the mobility of Ca2+ within a plant, resulting in Ca2+ deficiency and STN. STN of in vitro shoots or plantlets can be halted or reversed by altering the basal medium, mainly the concentration of Ca2+, adjusting the levels of auxins or cytokinins, or modifying culture conditions. This review examines the literature related to STN, seeks to discover the associated factors and relations between them, proposes practical solutions, and attempts to better understand the mechanism(s) underlying this condition in vitro.
