Iwona Żur et al.
Miscanthus × giganteus is a popular energy crop, which due to its hybrid origin is only vegetatively reproduced. Asexual embryogenesis in anther and microspore culture leading to double haploids production could allow to regain the ability...

The genetic mechanisms causing seed development by gametophytic apomixis in plants are predominantly unknown. As apomixis is consistently associated with hybridity and polyploidy, these confounding factors may either (a) be the underlying m...
Arabinogalactan protein profiles and distribution patterns during microspore embryogenesis and pollen development in Brassica napus [0.03%]
甘蓝型油菜小孢子胚状体和花粉发育过程中的半乳糖蛋白质的模式分析

Ahmed-Abdalla El-Tantawy et al.
Arabinogalactan proteins (AGPs), present in cell walls, plasma membranes and extracellular secretions, are massively glycosylated hydroxyproline-rich proteins that play a key role in several plant developmental processes. After stress treat...
Isolation and characterization of multiple F-box genes linked to the S9- and S10-RNase in apple (Malus × domestica Borkh.) [0.03%]
苹果(F-box基因与S9-和S10-RNase连锁及特性分析
Kazuma Okada,Shigeki Moriya,Takashi Haji et al.
Kazuma Okada et al.
Using 11 consensus primer pairs designed from S-linked F-box genes of apple and Japanese pear, 10 new F-box genes (MdFBX21 to 30) were isolated from the apple cultivar 'Spartan' (S(9)S(10)). MdFBX21 to 23 and MdFBX24 to 30 were completely l...
Pollen tube entry into the synergid cell of Arabidopsis is observed at a site distinct from the filiform apparatus [0.03%]

In higher plants, the double-fertilization process begins with the successful delivery of two sperm cells to the female gametophyte. The sperms cells are carried by a pollen tube that upon arrival at the micropylar end of the female gametop...
Arabidopsis RPG1 is important for primexine deposition and functions redundantly with RPG2 for plant fertility at the late reproductive stage [0.03%]
RPG1在拟南芥角质层初生沉积及生殖晚期植株育性中与RPG2冗余作用的研究
Ming-Xi Sun,Xue-Yong Huang,Jun Yang et al.
Ming-Xi Sun et al.
Arabidopsis Ruptured Pollen Grain-1 (RPG1/Sweet8) is a member of the MtN3/saliva protein family that functions as a sugar transporter. The rpg1 mutant shows defective exine pattern formation. In this study, transmission electron microscopy ...
Volume-based pollen size analysis: an advanced method to assess somatic and gametophytic ploidy in flowering plants [0.03%]
基于体积的花粉尺寸分析：评估开花植物体细胞和配子体多倍性的高级方法
Nico De Storme,Linda Zamariola,Martin Mau et al.
Nico De Storme et al.
Pollen size is often used as a biological parameter to estimate the ploidy and viability of mature pollen grains. In general, pollen size quantification is performed one- or two-dimensionally using image-based diameter measurements. As thes...

Expression datasets relating to the Arabidopsis female gametophyte have enabled the creation of a tool set which allows simultaneous visual tracking of each specific cell type (egg, synergids, central cell, and antipodals). This cell-specif...
Genetic separation of autonomous endosperm formation (AutE) from the two other components of apomixis in Hieracium [0.03%]
火绒草属中自主胚乳形成（AutE）的遗传分离及其他两种无融合生殖组分的隔离

Daisuke Ogawa et al.
In apomictic Hieracium subgenus Pilosella species, embryo sacs develop in ovules without meiosis. Embryo and endosperm formation then occur without fertilization, producing seeds with a maternal genotype encased in a fruit (achene). Genetic...
