Background Podocarpus lambertii (Podocarpaceae) is a native conifer from the Brazilian Atlantic Forest Biome, which considered one of 25 biodiversity hotspots in world. The advancement next-generation sequencing technologies has enabled rapid acquisition whole chloroplast (cp) genome sequences at low cost. Several studies have proven potential cp genomes as tools to understand enigmatic and basal phylogenetic relationships different taxonomic levels, well further probe structural functional...

Background Performing chloroplast DNA (cpDNA) isolation is considered a major challenge among different plant groups, especially conifers. Isolating chloroplasts in conifers by such conventional methods as sucrose gradient and high salt has not been successful. So far, plastid genome sequencing protocols for conifer species have based mainly on long-range PCR, which known to be time-consuming difficult implement. Methodology/Principal Findings We developed protocol cpDNA using three...

Climate change will inevitably lead to environmental variations, thus plant drought tolerance be a determinant factor in the success of plantations and natural forestry recovery. Some metabolites, such as soluble carbohydrates amino acids, have been described being key both embryogenesis efficiency abiotic stress response, contributing phenotypic plasticity adaptive capacity plants. For this reason, our main objectives were evaluate if temperature during embryonal mass initiation radiata...

Aleppo pine (Pinus halepensis Mill.), a native species of the Mediterranean region, has been suggested as that when introduced in degraded areas could facilitate long-term colonization and expansion late-successional species. Due to climate changes, plants need withstand extreme environmental conditions through adaptation changings developmental pathways. Among other paths, undergo changes pathways controlled by phytohormones. At same time, somatic embryogenesis widely used model understand...
