S29 haplotype does not require the MLPK function for self-incompatibility in Brassica rapa. Self-incompatibility (SI) in Brassicaceae is regulated by the self-recognition mechanism, which is based on the S-haplotype-specific direct interact...

The main features of generative cell morphogenesis, formation of a cytoplasmic projection and elongation of the GC body, operate through independent genetic pathways. Male gametogenesis in developing angiosperm pollen involves distinctive c...
Looking for non-hermaphrodite cacti: multidisciplinary studies in Gymnocalycium bruchii endemic to central Argentina [0.03%]
寻找非两性的仙人掌：阿根廷特有物种Gymnocalycium bruchii的多学科研究

Natalia E Delbón et al.
Through a multidisciplinary study we found that Gymnocalycium bruchii, an endemic cactus from central Argentina, acts as a dioecious species, which is the first record in this genus. Cactaceae species are typically hermaphroditic; however, ...
Ontogeny of the pollinium in Hoya carnosa provides new insights into microsporogenesis [0.03%]
霍顿亚 carnosa 的 pollinium 胚胎学提供了对微孢子发生的新见解

Yan-Feng Kuang et al.
The presence of a pollinium is a distinct character in Apocynaceae which is important for phylogenetic analysis. The pollinium of Hoya has an outer sporopollenin wall and a pellucid margin which are adaptive features. However, their ontogen...

Callose, a β-1,3-glucan, lines the pollen tube cell wall except for the apical growing region, and it constitutes the main polysaccharide in pollen tube plugs. These regularly deposited plugs separate the active portion of the pollen tube ...
Heat stress promotes haploid formation during CENH3-mediated genome elimination in Arabidopsis [0.03%]
热应激促进拟南芥中CENH3介导的基因组消除期间单倍体形成

Chunlian Jin et al.
Impaired activity of centromeric histone CENH3 causes inaccurate chromosome segregation and in crosses between the Arabidopsis recombinant CENH3 mutant GFP-tailswap and CENH3G83E with wild-type pollen it results in chromosome loss with the ...
