Frontiers in Plant Science, 2019 Apomixis (asexual seed formation) in angiosperms occurs either sporophytically, through adventitious embryony, or gametophytically, where an unreduced female gametophyte (embryo sac) forms and produces an unreduced egg that develops into an embryo ...

BMC Genomics, 2021 Background Apomixis, an asexual mode of plant reproduction, is a genetically heritable trait evolutionarily related to sexuality, which enables the fixation of heterozygous genetic combinations through the development of maternal seeds.

Tetraploidisation is a common phenomenon in apomictic Citrus seedlings affected by genotype and environmental conditions [PDF]
, 2009 Citrus species are mainly diploid (2n=2x=18) and very few natural polyploid are encountered in the citrus gene pool. However, several reports of tetraploid seedlings occurrence from apomictic citrus have been done during the last century.

Harnessing the developmental potential of nucellar cells: Barriers and opportunities [PDF]
, 2004 Angiosperm nucellar cells can either use or avoid meiosis in vivo, depending on the developmental context. This unique ability contrasts with the conditions required in vitro, either for a reconstituted oocyte to avoid meiosis and produce clones by ...

Identification of ovule transcripts from the Apospory-Specific Genomic Region (ASGR)-carrier chromosome [PDF]
, 2011 Background Apomixis, asexual seed production in plants, holds great potential for agriculture as a means to fix hybrid vigor. Apospory is a form of apomixis where the embryo develops from an unreduced egg that is derived from a somatic nucellar cell, the

The Plant Genome, Volume 19, Issue 2, June 2026.Abstract Polyploidization has played a key role in plant genome evolution. Eragrostis curvula (Schrad.) Ness, a perennial forage grass species of the Poaceae family, is an excellent model for investigating genome duplication due to its natural variation in ploidy levels.

Coppice potential of 16 different species of Eucalyptus after an eight-year rotation [PDF]
, 2019 The adoption of coppice is a commonly used management in different regions of Brazil for plantations of Eucalyptus, which requires less investments. However, there are variations in the ability of each genotype to emit sprouts, and higher yields can be ...

The Plant Genome, Volume 19, Issue 2, June 2026.Abstract The genus Citrus is characterized by a reticulate evolutionary history with frequent hybridization, making it an intriguing subject for genome evolution investigation. Citrus changshan‐huyou Y. B. Chang (Huyou) is a unique landrace first discovered in Zhejiang Province, China, with premium fruit quality.

More than symbioses : orchid ecology ; with examples from the Sydney Region [PDF]
, 2013 The Orchidaceae are one of the largest and most diverse families of flowering plants. Orchids grow as terrestrial, lithophytic, epiphytic or climbing herbs but most orchids native to the Sydney Region can be placed in one of two categories.
