Clonal reproduction by seed of a cultivated hybrid plant: a new perspective for small-scale rice growers

Comptes Rendus Biologies
Transferring an asexual mode of reproduction by seeds (apomixis) to cultivated plants would enable clonal reproduction of heterozygous genotypes such as F1 hybrids with hybrid vigor (heterosis), facilitating their access and multiplication by small-scale

The Boechera Genus as a Resource for Apomixis Research

Frontiers in Plant Science, 2019
The genera Boechera (A. Löve et D. Löve) and Arabidopsis, the latter containing the model plant Arabidopsis thaliana, belong to the same clade within the Brassicaceae family.

Repeatability, Genetic Variability and Importance of Forage Traits in Ecotypes of Brunswickgrass (Paspalum nicorae Parodi) via BLUP

Plant Breeding, EarlyView.
ABSTRACT This study estimated the repeatability of forage traits in 84 Paspalum nicorae ecotypes using six statistical methods and quantified the minimum number of harvests needed for effective selection. Multivariate analyses based on best linear unbiased prediction (BLUP) values were also performed to assess genetic variability, identify key traits ...

Apospory and Diplospory in Diploid Boechera (Brassicaceae) May Facilitate Speciation by Recombination-Driven Apomixis-to-Sex Reversals

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 ...

In Vivo Propagation of Root Explants of the Dandelion Species Taraxacum kok‐saghyz, Taraxacum officinale and Their Interspecific Hybrids

Plant Breeding, EarlyView.
ABSTRACT The dandelion species Taraxacum kok‐saghyz is a promising new crop for natural rubber production and is currently in the early stages of the breeding process. To support these efforts, the multiplication and conservation of defined genotypes are crucial.

A study of the heterochronic sense/antisense RNA representation in florets of sexual and apomictic Paspalum notatum

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.

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 ...

Nectaries and reproductive biology of croton sarcopetalus (euphorbiaceae) [PDF]

, 2001
Flower morphology, nectary structure, nectar chemical composition, breeding system, floral visitors and pollination were analysed in Croton sarcopetalus, a diclinous-monoecious shrub from Argentina.

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.
