Maximization of Markers Linked in Coupling for Tetraploid Potatoes via Monoparental Haploids

Frontiers in Plant Science, 2018
Haploid potato populations derived from a single tetraploid donor constitute an efficient strategy to analyze markers segregating from a single donor genotype.

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 ...

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.

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 ...

GERMIN3 regulates tuber initiation and axillary bud activation by facilitating plasmodesmatal gating

The Plant Journal, Volume 122, Issue 2, April 2025.
Significance Statement We present evidence that GERMIN3 lies downstream of the tuberigen activation complex (and possibly the florigen activation complex) to regulate plasmodesmatal (PD) gating to facilitate the flux of sucrose to meristems leading to meristem activity and downstream developmental processes.

Distinct effects of PTST2b and MRC on starch granule morphogenesis in potato tubers

Plant Biotechnology Journal, Volume 23, Issue 2, Page 412-429, February 2025.
Summary The molecular mechanisms underpinning the formation of the large, ellipsoidal starch granules of potato tuber are poorly understood. Here, we demonstrate the distinct effects of PROTEIN TARGETING TO STARCH2b (PTST2b) and MYOSIN RESEMBLING CHLOROPLAST PROTEIN (MRC) on tuber starch granule morphology.

StCDF1: A ‘jack of all trades’ clock output with a central role in regulating potato nitrate reduction activity

New Phytologist, Volume 245, Issue 1, Page 282-298, January 2025.
Summary Transcription factors of the CYCLING DOF FACTOR (CDF) family activate in potato the SP6A FT tuberization signal in leaves. In modern cultivars, truncated StCDF1.2 alleles override strict SD control by stabilizing the StCDF1 protein, which leads to StCOL1 suppression and impaired activation of the antagonic SP5G paralog. By using DAP‐seq and RNA‐
