The structure and allelic diversity of the self‐incompatibility locus (S‐locus) in diploid potatoes inferred from genome sequences and transcriptome data from styles and pollen

The Plant Genome, Volume 18, Issue 4, December 2025.
Abstract Gametophytic self‐incompatibility (GSI) is a reproductive strategy to prevent inbreeding and promote outcrossing. Studies to understand molecular and evolutionary aspects of the self‐compatibility (SC)/self‐incompatibility (SI) system in the Solanaceae have been conducted using several genera including Petunia Juss., Nicotiana L., and Solanum ...

Two tandem R2R3 MYB transcription factor genes cooperatively regulate anthocyanin accumulation in potato tuber flesh

Plant Biotechnology Journal, Volume 23, Issue 5, Page 1521-1534, May 2025.
Summary Anthocyanin biosynthesis and accumulation determines the colour of tuber flesh in potato (Solanum tuberosum) and influences nutritional quality. However, the regulatory mechanism behind anthocyanin biosynthesis in potato tuber flesh remains unclear.

Modified carbon dot‐mediated transient transformation for genomic and epigenomic studies in wheat

Plant Biotechnology Journal, Volume 23, Issue 4, Page 1139-1152, April 2025.
Summary Genotype restriction poses a significant bottleneck to stable transformation in the vast majority of plant species, thereby severely impeding advancement in plant bioengineering, particularly for crops. Nanoparticles (NPs) can serve as effective carriers for the transient delivery of nucleic acids, facilitating gene overexpression or silencing ...

Biocontrol of Rhizoctonia solani in native potato (Solanum phureja) plants using native Pseudomonas fluorescens

Acta Biológica Colombiana, 2007
Rhizoctonia solani is a soil borne phytopathogen associated with reduced plant vigor and tuber production in potato crops. There is a huge interest to search alternatives of biological control management of this disease, because the potato crops in ...

Jan and mini‐Jan, a model system for potato functional genomics

Plant Biotechnology Journal, Volume 23, Issue 4, Page 1243-1256, April 2025.
Summary Potato (Solanum tuberosum) is the third‐most important food crop in the world. Although the potato genome has been fully sequenced, functional genomics research of potato lags behind that of other major food crops, largely due to the lack of a model experimental potato line.
