Pollen grains are male gametophytes produced within the pollen sacs of the anthers of the flower. Recent genetic studies have revealed several components involved in microspore development (Borg et al., 2009; Berger and Twell, 2011), and yet many ...

Embryological features, pollen and seed viability of Arnica montana (Asteraceae) – a threatened endemic species in Europe [PDF]
The embryological features, mode of reproduction and reproductive capacity (pollen and seed viability) on two naturalized populations of Arnica montana in Bulgaria were studied. The embryological study shows that A.

Nuclear bodies domain changes with microspore reprogramming to embryogenesis
We analysed the presence of nuclear bodies and particularly Cajal bodies during representative stages of gametophytic and haploid embryogenic development in isolated microspore and anther cultures of a model system (Brassica napus cv.

The Study of Ultrastructure、ATP、Calcium and RNA-Seq in fertile and sterile anthers of Lycium Barbarum L. [PDF]
高等植物的雄性不育是杂种优势利用的基础,避免了去雄的繁杂程序。植物雄性不育的种类很多,形成原因也很复杂,对雄性不育机理的探索一直是一个热门研究领域。枸杞雄性不育系是近年来新发现的一种不育类型,具有很大应用潜力,为了明确其雄性不育发生的机制并更好地开发利用这一宝贵种质资源,我们从结构、生理和分子生物学等几个方面展开了研究。 本研究以可育系宁杞1号和不育系宁杞5号为实验材料,用超微结构、ATPase和Ca2+的细胞化学定位,以及转录组和数字基因表达谱研究了枸杞花药发育的特征并比较了不育花药形态 ...
