Establishment of molecular markers for early selection of embryogenic cultures with
high embryogenic potential in Brazilian pine (Araucaria angustifolia (BERT) O. KTZE).
Brazilian pine (Araucaria angustifolia (Bert) O. Ktze) is the only native conifer species
with economic importance in Brazil. Recently, due to intensive exploitation Brazilian
pine was included in the official list of endangered Brazilian plants. Biotechnology
tools, like somatic embryogenesis (SE), may become a potentially useful tool for mass
clonal propagation and ex situ conservation of commercial and endangered plant
species, especially conifers. SE involves the coordinated execution of four steps:
embryogenic culture (EC) induction, proliferation, maturation, and plant regeneration.
As observed for other conifers, the presence of well-developed early somatic embryos
(SE) in EC of Brazilian pine can be considered the pre-requisite for embryo maturation
in a medium supplemented with abscisic acid (ABA) and osmotic agents. However, in
some genotypes even the presence of bipolar SE does not guarantee embryo
maturation. Since SE morphology cannot be used as the only factor for EC selection,
the development of molecular markers for early detection of embryogenic cultures
responsive to maturation promoters (ABA and osmotic agents) is highly desirable. By
using proteomic and transcriptomic approaches, the present project aims the gene
expression pattern characterization of somatic and zygotic embryos in order to identify
molecular markers that could assist the selection of EC that could be used for ex situ
