Oil Palm Germplasm Resources and Their Conservation: Advances and Challenges for In Vitro Conservation [PDF]

Plants
In vitro germplasm conservation provides an alternative method for preserving plant species that are vulnerable to natural hazards or for which in situ conservation is costly and challenging to manage. This review examines the significance and challenges associated with various in vitro conservation methods.

In Vitro Micropropagation of Native Ulluco (Ullucus tuberosus Caldas) from the Amazonas Region of Peru [PDF]

Plants
Ulluco (Ullucus tuberosus Caldas) is an Andean tuber crop of high nutritional and genetic importance. However, its vegetative propagation promotes the accumulation of pathogens and limits the availability of uniform, high-quality planting material.

Identification of novel and conserved miRNAs in leaves of in vitro grown Citrus reticulata Lugan plantlets by Solexa sequencing

Frontiers in Plant Science, 2016
MicroRNAs (miRNAs) play essential roles in plant development, but the roles in the in vitro plant development are unknown. Leaves of ponkan plantlets derived from mature embryos at in vitro culture conditions were used to sequence small RNA fraction via ...

The Diverse Assemblage of Fungal Endophytes from Orchids in Madagascar Linked to Abiotic Factors and Seasonality

Diversity, 2021
The inselbergs of the Central Highlands of Madagascar are one of many ‘micro-hotspots’ of biodiversity on the island, particularly for Orchidaceae. In this region are several genera that have a large number of endemic species that are in serious decline ...

Conservation of Citrus Germplasm in Vitro [PDF]

Journal of the American Society for Horticultural Science, 1991
A study was conducted to evaluate the potential of in vitro techniques for genetic conservation of citrus. A tissue culture system was developed using explants of juvenile `Pineapple' sweet orange. It consisted of: a) establishment of primary cultures from nodal stem segments followed by the recovery of plants in vitro; and b ...

A conservation law for virus infection kinetics in vitro [PDF]

Journal of Theoretical Biology, 2015
Conservation laws are among the most important properties of a physical system, but are not commonplace in biology. We derived a conservation law from the basic model for viral infections which consists in a small set of ordinary differential equations.
