Cyto-Embryological Analysis of Wild Kentucky Bluegrass Germplasm in Gansu Province, China
Agronomy, 2023 Reproduction studies, particularly embryology, represent basic information of any plant. However, the current embryological information is fragmentary for Kentucky bluegrass (Poa pratensis L.).

The MAPK homolog, Smk1, promotes assembly of the glucan layer of the spore wall in S. cerevisiae. [PDF]
YeastSpore walls in Saccharomyces cerevisiae are multilayered structures consisting of inner layers that resemble the vegetative cell wall, and spore‐specific outer layers that protect the products of meiosis from environmental insults. In this study, a mutant that blocks assembly of the outer layers of the spore wall (cda1,2∆) is used to demonstrate that a

Temporal and spatial expression of genes involved in DNA methylation during reproductive development of sexual and apomictic Eragrostis curvula [PDF]
, 2017 Recent reports in model plant species have highlighted a role for DNA methylation pathways in the regulation of the somatic-to-reproductive transition in the ovule, suggesting that apomixis (asexual reproduction through seeds) likely relies on RdDM ...
