Efficient and versatile rapeseed transformation for new breeding technologies

The Plant Journal, Volume 123, Issue 1, July 2025.
SUMMARY Many gene functions are widely studied and understood in Arabidopsis; however, the lack of efficient transformation systems often limits the application and verification of this knowledge in crop plants. Brassica napus L., a member of the Brassicaceae family, is usually transformed by Agrobacterium‐mediated hypocotyl transformation, but not all

Advancements in hybrid rice production: improvements in male sterility and synthetic apomixis for sustainable agriculture

Plant Biotechnology Journal, Volume 23, Issue 6, Page 2330-2345, June 2025.
Summary Rice serves as a staple food for approximately half of the world's population, and enhanced yields from hybrid rice play a crucial role in ensuring food security and augmenting incomes. However, the annual purchase and high cost of hybrid seeds hinder widespread hybrid rice adoption.

CTB6 Confers Cold Tolerance at the Booting Stage by Maintaining Tapetum Development in Rice

Advanced Science, Volume 12, Issue 10, March 13, 2025.
In this study, we cloned a novel cold‐tolerance gene, CTB6, from the Yunnan plateau cultivar KMXBG. CTB6 is mainly expressed in the tapetum and young microspores of anthers. It regulates tapetum development by maintaining the stability of catalases and increases the lipid content in anthers to enhance the cold tolerance at the booting stage in rice ...

Defined Nuclear Changes Accompany the Reprogramming of the Microspore to Embryogenesis

Journal of Structural Biology, 2000
The switch of the gametophytic developmental program toward pollen embryogenesis to form a haploid plant represents an important alternative for plant breeding. In the present study, the switch of the gametophytic developmental program toward a sporophytic pathway, "embryogenesis," has been studied in three different plant species, Brassica, tobacco ...

GOLEM: A tool for visualizing the distribution of Gene regulatOry eLEMents within the plant promoters with a focus on male gametophyte

The Plant Journal, Volume 121, Issue 5, March 2025.
Significance Statement Precise localization and visualization of gene regulatory motifs in gene promoters, in relation to gene transcription in specific tissues, can be challenging, especially for researchers without advanced bioinformatics expertise. GOLEM (Gene regulatOry eLEMents) is a freely available tool that enables users to precisely locate any

Efficient isolated microspore culture protocol for callus induction and plantlet regeneration in japonica rice (Oryza sativa L.)

Plant Methods
Background Isolated microspore culture is a useful biotechnological technique applied in modern plant breeding programs as it can produce doubled haploid (DH) plants and accelerate the development of new varieties.

The effect of phytosulfokine alpha on haploid embryogenesis and gene expression of Brassica napus microspore cultures

Frontiers in Plant Science
Microspore embryogenesis (ME) is the most powerful tool for creating homozygous lines in plant breeding and molecular biology research. It is still based mainly on the reprogramming of microspores by temperature, osmotic and/or nutrient stress.

Efficient Production of Doubled Haploid Plants through Microspore Culture in Brassica napus

浙江大学学报. 农业与生命科学版, 2000
Since haploid embryoids were first obtained from microspore culture of Brassica napus there has been a rapid progress in the application of this technique in genetic studies and breeding utilization of rapeseed.

Exploring the diversity of galls on Artemisia indica induced by Rhopalomyia species through morphological and transcriptome analyses

Plant Direct, Volume 8, Issue 7, July 2024.
Abstract Plant galls generated by insects have highly organized structures, providing nutrients and shelter to the insects living within them. Most research on the physiological and molecular mechanisms of gall development has focused on single galls.
