Gametophytic Self-Incompatibility Systems [PDF]
is one of the mechanisms that have evolved to encourage outbreeding in flowering plants and is defined as “the inability of a fertile hermaphrodite seed plant to produce zygotes after self-pollination” (de Nettancourt, 1977). The effectiveness of SI in promoting outbreeding is believed to be one of the most important factors that ensured the evolu ...

microRNA‐mediated control of cell fate specification and patterning in Marchantia polymorpha
The gemma developmental program in Marchantia polymorpha is coordinated by MpMIR166‐mediated repression of MpC3HDZ and auxin homeostasis. Summary MicroRNAs (miRNAs) are small non‐coding RNA molecules essential for growth and development in eukaryotes. In plants, the master gene DICER‐LIKE 1 (DCL1) catalyzes the biogenesis of miRNAs by processing double‐

Transcript correlation analysis allowed the identification of several key nodes in the complex regulatory network of plant iron metabolism. Abstract Arabidopsis thaliana was the first plant genome to be fully sequenced, almost a quarter of a century ago, thanks to The Arabidopsis Genome Initiative, with contributions from scientists worldwide.

Abstract Introduction Biological soil crusts (biocrusts) are key components of soil ecosystems and promising tools for ecological restoration. Mosses, as important biocrust constituents, contribute to ecosystem functioning but often fail to establish after inoculation due to harsh environmental constraints.

Abstract Society generally presents sex inaccurately as a binary variable based on one or few trait(s), causing myriad issues, including the pursuit of reductionist biology experiments, the creation of laws that limit the rights of women, people with queer genders, and intersex folks, and greater student endorsement of gender stereotypes in ...

Life after meiosis: patterning the angiosperm male gametophyte
Pollen grains represent the highly reduced haploid male gametophyte generation in angiosperms. They play an essential role in plant fertility by generating and delivering twin sperm cells to the embryo sac to undergo double fertilization.

Control of Male Gametophyte Development [PDF]
In a previous review of male gametophyte development ([McCormick, 1993][1]), it was noted that the two areas posed by [Mascarenhas (1975)][2] as fruitful areas for future research were the following.
