Engineering root development with high precision
New Phytologist, EarlyView.Conceptual framework for precise engineering of root development. Summary Root development is controlled by dynamic interactions between gene regulation, hormonal signalling, developmental history and environmental inputs, creating multiple layers of control that can be harnessed for engineering.

Belowground growth is the primary driver of radial oxygen loss from Typha angustifolia to sediment
New Phytologist, EarlyView.Oxygen pool accompanying the growth of a new Typha angustifolia rhizome through anoxic sediment. Summary Wetland plants must supply oxygen to their rhizomes and roots to maintain aerobic respiration despite soil anoxia. Excess oxygen can diffuse into the environment, strongly affecting rhizosphere biogeochemistry.

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 ...

miR172‐AP2 Controls Age‐Dependent Regeneration Competence in Populus
Plant Biotechnology Journal, EarlyView.ABSTRACT Plants maintain remarkable regenerative potential, yet this capacity declines with developmental age, limiting clonal propagation and biotechnological applications. Here, we show that the miR172‐AP2 module serves as a central determinant of regeneration competence in Populus.

Single‐Nucleus Transcriptome Analysis Provides New Insights Into B Chromosome Elimination in Sorghum
Plant Biotechnology Journal, EarlyView.ABSTRACT B chromosomes are supernumerary entities found in many plant species, with some exhibiting tissue‐specific elimination. In Sorghum purpureosericeum, extensive B chromosome elimination occurs during embryogenesis affecting most of the embryonic organs, leaving the B chromosome maintained mainly in limited regions of meristems.
