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 ...

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

Plant Biotechnology Journal, EarlyView.
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 ...

Cytological development, calcium dynamic and metabolite profile of stress-induced tobacco (Nicotiana tabacum L.) microspore under calcium chloride treatment [PDF]

Brazilian Journal of Biology
Exogenous calcium is pivotal in activating microspore embryogenesis via calcium signaling. Altering the external calcium levels in the medium has been documented to impact the success rate of microspore embryogenesis initiation.

Doubled haploid ramets via embryogenesis of haploid tissue cultures [PDF]

, 2010
Tissue culture in the oil palm business is generally concerned with the multiplication (clonal production) of dura, pisifera and tenera palms. These are all normal diploids (2n=2x=36).

Assessing the adaptive potential of European beech populations to temperature and precipitation along a steep environmental gradient in the south‐eastern Carpathians

Plant Biology, EarlyView.
This study focuses on the identification of candidate SNPs involved in local adaptation to altitude by environmental association analysis conducted on different natural European beech (Fagus sylvatica) populations. Abstract It is necessary to assess the adaptive potential of European beech populations to climate change.

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 ...

Evolution of molecular communication in the permanent Azolla symbiosis

New Phytologist, Volume 249, Issue 4, Page 1666-1674, February 2026.
Summary Heritable symbioses exist across eukaryotes with different degrees of intimacy. In most cases, the symbionts are obligate and require inheritance for their survival. On the host side, symbiont retention can facilitate fitness benefits. Only rarely are these symbioses interwoven to the point that host survival relies on the symbiont.

Current insights into hormonal regulation of microspore embryogenesis

Frontiers in Plant Science, 2015
Plant growth regulator (PGR) crosstalk and interaction with the plant’s genotype and environmental factors play a crucial role in microspore embryogenesis (ME), controlling microspore-derived embryo differentiation and development as well as haploid ...
