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 ...

Aborted microspores acts as a master regulator of pollen wall formation in Arabidopsis [PDF]
, 2014 Mature pollen is covered by durable cell walls, principally composed of sporopollenin, an evolutionary conserved, highly resilient, but not fully characterized, biopolymer of aliphatic and aromatic components.

Czech Journal of Genetics and Plant Breeding, 2012 This review describes sources of structures of non-microspore origin observed in anther and microspore cultures. Various characteristics of these structures may cause a wrong diagnosis of these structures as embryos or cell/tissue clusters of microspore ...

Dissecting meiotic recombination based on tetrad analysis by single-microspore sequencing in maize
Nature Communications, 2015 Meiotic recombination drives eukaryotic sexual reproduction and the generation of genome diversity. Tetrad analysis, which examines the four chromatids resulting from a single meiosis, is an ideal method to study the mechanisms of homologous ...

Pollen development in Mill. (Annonaceae). Implications for the evolution of aggregated pollen [PDF]
, 2009 In most flowering plants, pollen is dispersed as monads. However, aggregated pollen shedding in groups of four or more pollen grains has arisen independently several times during angiosperm evolution.

The Distribution of Calcium during the Anther Development of Celosia argentea L. [PDF]
, 2015 植物花药发育过程中发生了许多独特的生物学事件，如小孢子母细胞减数分裂、小孢子母细胞的胼胝质壁形成和四分体胼胝质壁降解、孢粉素花粉壁的形成、小孢子的不对称分裂等，一直都是植物发育生物学领域关注的热点问题。Ca2+是植物生长发育过程中的重要元素,它不仅具有重要的生理功能,也是一种胞内信号分子,在细胞分化过程中具有很多重要功能。Ca2+参与植物有性生殖过程中的许多环节,在被子植物有性生殖过程中Ca2+的功能也越来越多地被揭示。本研究应用焦锑酸盐沉淀法定位钙离子，用透射电镜技术对青葙 ...

Marker-free transgenic plants through genetically programmed auto-excision [PDF]
, 2007 We present here a vector system to obtain homozygous marker-free transgenic plants without the need of extra handling and within the same time frame as compared to transformation methods in which the marker is not removed.
