Whole‐genome duplication promotes phenotypic and genetic adaptation to elevation

New Phytologist, EarlyView.
Fitness of diploids (2x) and tetraploids (4x) of Biscutella laevigata from low (circles) and high (triangles) elevation transplanted across elevation at 585, 1236 and 1967 m above sea level. Summary Whole‐genome duplication (WGD) is often considered as either an adaptive dead‐end or a facilitator of rapid adaptation under changing environments.

In vitrotetraploid induction and generation of tetraploids from mixoploids inDioscorea zingiberensis

Pharmacognosy Magazine, 2010
This article describes an efficient colchicine-mediated technique for the in vitro induction of tetraploids in Dioscorea zingiberensis and its confirmation by flow cytometry. Buds immersed in 0.2% colchicine solution for 36 hours prior to culture induced as high as 35.6% tetraploid plants. Colchicine-induced tetraploids remained stable after six months

Linking drought strategy to climate‐of‐origin in a widespread C4 grass: hydraulic traits, xylem anatomy and stomatal behaviour in Themeda triandra

New Phytologist, EarlyView.
Climate‐of‐origin of Themeda triandra populations used in this study. Summary Hydraulic, stomatal, and anatomical traits strongly influence plant performance under drought, but the extent to which these trait‐types are coordinated and relate to climate‐of‐origin remains vastly underexplored in herbaceous species relative to woody plants.

Effects of In Vitro Polyploidization on Agronomic Characteristics and Fruit Carotenoid Content; Implications for Banana Genetic Improvement

Frontiers in Plant Science, 2019
Bananas (Musa spp.), native to South East Asia, have spread worldwide and are integrated into the diets of millions of people in tropical regions. Carotenoid content varies dramatically between different banana genotypes, providing an opportunity for ...

Induction and Flow Cytometry Identification of Tetraploids from Seed-Derived Explants through Colchicine Treatments in Catharanthus roseus (L.) G. Don

Journal of Biomedicine and Biotechnology, 2011
The tetraploid plants of Catharanthus roseus (L.) G. Don was obtained by colchicine induction from seeds explants, and the ploidy of the plants was identified by flow cytometry.

High‐Contiguity Haplotype‐Resolved Genome Assembly of the Hexaploid Actinidia valvata Rootstock Sheds Light on Waterlogging Resistance Gene

Plant Biotechnology Journal, EarlyView.
ABSTRACT Polyploidisation, creating redundant or diverged copies of the genome, is a major driving force in plant evolution, diversification and environmental adaptation, including for the kiwifruit genus (Actinidia Lindl.). We present a high‐contiguity, haplotype‐resolved genome assembly of the hexaploid Actinidia valvata rootstock cultivar ...

Programmable Domestication: CRISPR, Pan‐Genomics and System Level Engineering for Next‐Generation Crops

Plant Biotechnology Journal, EarlyView.
Conceptual overview of programmable de novo domestication from genetic diversity discovery to crop deployment. The framework connects diverse germplasm and genomic resources with three trajectory pathways. Adaptive Rescue, Agronomic Refinement and Novel Chassis defined by biological distance, engineering complexity and breeding objectives.

Comparative Genome‐Wide Association Studies of Metabolites and Grain‐Related Traits in Common Wheat

Plant Biotechnology Journal, EarlyView.
ABSTRACT The metabolome is highly diverse and the closest layer to phenotype; therefore, it is commonly regarded as a bridge between the genome and phenome in plants. Here, we performed large‐scale metabolome analysis using liquid chromatography–tandem mass spectrometry (LC–MS/MS) and 33 grain‐related traits in a diverse panel of natural accessions and
