Haploid Mutation Mapping Identifies a Homoeologous Non‐Reciprocal Translocation Linked to Reduced Fibre and Enhanced Protein in Brassica napus

open access: yesPlant Biotechnology Journal, Volume 24, Issue 5, Page 3219-3243, May 2026.
ABSTRACT A key challenge for the genetic improvement of canola (Brassica napus), one of the world's most important oilseeds, is the limited natural variation for commercially important traits. The creation of new variation is hindered by the lack of functional knowledge about genes controlling these traits.

OsMT2b Regulates Pollen Development and ROS Homeostasis in a Photoperiod‐Dependent Manner

open access: yesPlant Biotechnology Journal, Volume 24, Issue 5, Page 3051-3064, May 2026.
ABSTRACT Reactive oxygen species (ROS) are signalling molecules that promote programmed cell death in animal and plant systems. However, their role in rice (Oryza sativa L.) anther development is unclear. In this study, we show that lower transcript levels of the metallothionein gene OsMT2b in japonica rice plants obtained by RNA interference (RNAi ...

Cultivating Callus from Anthers and Regenerating Haploid Plants in Lilium longiflorum

open access: yesHorticulturae
In vitro anther culture is a technique used to produce haploid plants when regenerating varieties with specific traits. To generate haploid plants with preferred characteristics, an anther culture technique was established for Lilium longiflorum “Show Up”

A new microspore embryogenesis system under low temperature which mimics zygotic embryogenesis initials, expresses auxin and efficiently regenerates doubled-haploid plants in Brassica napus

open access: yesBMC Plant Biology, 2012
Background Microspore embryogenesis represents a unique system of single cell reprogramming in plants wherein a highly specialized cell, the microspore, by specific stress treatment, switches its fate towards an embryogenesis pathway.

Bioactivity Profiling of Coronarin A and Villosin Isolated From Hedychium coronarium J. Koenig: Acaricidal, Nematicidal, and Antifungal Potential

open access: yesChemistry &Biodiversity, Volume 23, Issue 4, April 2026.
The graphical abstract illustrates the flowchart for the isolation and evaluation of bioactive compounds from Hedychium coronarium. Crude extracts were obtained via cold percolation from the aerial parts (flowers, leaves, and stems) using dichloromethane (DCM) and from the rhizomes using chloroform.

High Frequency Production of Doubled Haploid Rapeseed Plants by Direct Colchicine Treatment of Isolated Microspores

open access: yes浙江大学学报. 农业与生命科学版, 2000
Techniques for microspore culture of Brassica napus have been improved rapidly, and embryogen-esis has been achieved in a wide range of genotypes. Plants regenerated from microspore-derived embryoids can be haploid, diploid or polyploid.
