Cultivating Callus from Anthers and Regenerating Haploid Plants in Lilium longiflorum

Horticulturae
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”

The metabolic incorporation of label from myoinositol-2-3H by the growing young anther of Lilium lorlgiflorum

Acta Societatis Botanicorum Poloniae, 2014
Fine structural autoradiography involving the incorporation of myo-inositol-2-3H (MI-2-3H) unto lily anther during development has been used to explore the metabolic processes of microspore development and the interation between the devlaping microspore ...

Redundant Glycerol‐3‐Phosphate Acyltransferases Regulate Thermo‐Sensitive Genic Male Sterility in Rice

Plant Biotechnology Journal, Volume 24, Issue 7, Page 4689-4703, July 2026.
ABSTRACT Thermo‐sensitive genic male sterility (TGMS) lines play a pivotal role in two‐line hybrid rice breeding. However, the availability of elite TGMS germplasm remains limited, and the molecular mechanisms underlying fertility transition of TGMS lines are still poorly understood.

Microspore embryogenesis in vitro: the role of stresses

Вавиловский журнал генетики и селекции, 2019
Gametic embryogenesis is one form of totipotency of plant cells, in which either male or female gametes are induced to form embryoids (sporophytes). Regeneration of haploid plants from embryoids and subsequent chromosome duplication result in doubled ...

Microspore Induced Doubled Haploids Production from Ethyl Methanesulfonate (EMS) Soaked Flower Buds Is an Efficient Strategy for Mutagenesis in Chinese Cabbage

Frontiers in Plant Science, 2016
Chinese cabbage buds were soaked with Ethyl methanesulfonate (EMS) to induce mutagenesis. The influence of different EMS concentrations and treatment durations on microspore development, embryo production rate and seedling rate were evaluated in five ...

Early evolutionary history of the seed

Biological Reviews, Volume 101, Issue 3, Page 1511-1553, June 2026.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Association of Floral Bud and Anther Size with Microspore Developmental Stage in Campari Tomato

, 2017
Successful anther/microspore culture largely depends on the use of microspores at appropriate developmental stages at the time of culture, which can be specific for each plant species and genotype.

Making Two out of One: Kinesin Motors Driving Plant Cell Division

Cytoskeleton, Volume 83, Issue 6, Page 384-393, June 2026.
ABSTRACT The Kinesin superfamily of microtubule dependent motors is present in all eukaryotes. Not all of the subfamilies are represented in all kingdoms, and the ones that are do not always show conserved functions. Tight control of the cytoskeleton is essential for proper progression and completion of mitosis and cytokinesis, and key functions are ...

Generative Cell Division, but Not Early Nuclear Reorganization, Requires Transcriptional Reactivation During Pollen Tube Growth

Plant Direct, Volume 10, Issue 6, June 2026.
ABSTRACT Bicellular pollen often enters a desiccated state wherein development is temporarily arrested, enabling long‐term survival while maintaining the capacity for rapid activation upon hydration. Although the generative cell in mature pollen of Lilium species is known to have completed DNA replication, its precise cell‐cycle status and the ...
