Plastid genome of Chenopodium petiolare from Trujillo, Peru.

Objectives: The Peruvian Andean region is an important center for plant domestication. However, to date, there have been few genetic studies on native grain, which limits our understanding of their genetic diversity and the development of new genetic studies for their breeding. Herein, we revealed the plastid genome of Chenopodium petiolare to expand our knowledge of its molecular markers, evolutionary studies, and conservation genetics.

Plastid genome of var. (poro-poro) from Huánuco, Peru.

var. , known locally as poro-poro, is an important native fruit used in traditional Peruvian medicine with relevant agro-industrial and pharmaceutical potential for its antioxidant capacity for human health. However, to date, only a few genetic data are available, which limits exploring its genetic diversity and developing new genetic studies for its improvement.

Simplifying plant gene silencing and genome editing logistics by a one-Agrobacterium system for simultaneous delivery of multipartite virus vectors.

Viral vectors provide a quick and effective way to express exogenous sequences in eukaryotic cells and to engineer eukaryotic genomes through the delivery of CRISPR/Cas components. Here, we present JoinTRV, an improved vector system based on tobacco rattle virus (TRV) that simplifies gene silencing and genome editing logistics. Our system consists of two mini T-DNA vectors from which TRV RNA1 (pLX-TRV1) and an engineered version of TRV RNA2 (pLX-TRV2) are expressed.
