Ecology and Evolution, Volume 14, Issue 5, May 2024.This study employed molecular markers and morphological studies of two populations of Monostroma nitidum collected from YJ and ZJ. The results revealed no obvious differences in tufA and 18S rDNA sequences between the two populations, although there were extremely significant differences in morphological characteristics. M.

On the presence of fertile gametophytes of Padina pavonica (Dictyotales, Phaeophyceae) from the Iberian coasts [PDF]
, 2007 The gametophytes of Padina pavonica (L.) Thivy have received little attention in literature. Both female and predominantly male monoecious gametophytes of P. pavonica are recorded for the first time in the Iberian Peninsula. A detailed description of the

Global transcriptome analysis of two ameiotic1 alleles in maize anthers: defining steps in meiotic entry and progression through prophase I [PDF]
, 2011 Background Developmental cues to start meiosis occur late in plants. Ameiotic1 (Am1) encodes a plant-specific nuclear protein (AM1) required for meiotic entry and progression through early prophase I. Pollen mother cells (PMCs) remain mitotic in most am1

Frontiers in Plant Science, 2016 Molecular dissection of apomixis - an asexual reproductive mode - is anticipated to solve the enigma of loss of meiotic sex, and to help fixing elite agronomic traits.

New Phytologist, Volume 242, Issue 3, Page 1348-1362, May 2024.Summary Asexual organisms often differ in their geographic distributions from their sexual relatives. This phenomenon, termed geographic parthenogenesis, has long been known, but the underlying factors behind its diverse patterns have been under dispute. Particularly problematic is an association between asexuality and polyploidy in most taxa. Here, we

Molecular control of autonomous embryo and endosperm development [PDF]
, 2018 Precocious seed development is usually prevented by a series of mechanisms that ensure seed production results from double fertilization. These events are circumvented in natural apomictic plant species that reproduce clonally through seed.

Genes modulating the increase in sexuality in the facultative diplosporous grass eragrostis curvula under water stress conditions [PDF]
, 2020 Eragrostis curvula presents mainly facultative genotypes that reproduce by diplosporous apomixis, retaining a percentage of sexual pistils that increase under drought and other stressful situations, indicating that some regulators activated by stress ...

Characterization of tissue specific expressed proteins and metabolites in Cenchrus polystachion (L.) Schult and their role in apomixis [PDF]
, 2020 Agricultural production can be aggrandized by adaptation of trending technologies or processes which focus on increase in seed production. Asexual reproduction in plants or Apomixis is such a process, but its absence in major crop plants has paved an ...

Pharmacologically Induced Meiosis Apomeiosis Interconversions in \u3ci\u3eBoechera\u3c/i\u3e, \u3ci\u3eArabidopsis\u3c/i\u3e and \u3ci\u3eVigna\u3c/i\u3e [PDF]
, 2018 Apomixis is a clonal propagation method that produces offspring identical to the mother plant. With this feature, superior traits could be maintained over generations. However, our knowledge about apomixis is limited.

Identification and genetic analysis of the APOSPORY locus in Hypericum perforatum L. [PDF]
, 2010 Der Induktion der Apomixis (Samenbildung ohne Befruchtung) in Kulturpflanzen stellt einen lang gehegten Ziel der Züchtungsforschung dar, da es die Fixierung der Heterozygotie ermöglichen würde.
