Strategies to Identify Adaptive Genes in Hybridizing Trees like Oaks and Poplars

open access: yesNotulae Botanicae Horti Agrobotanici Cluj-Napoca, 2014
Ecologically divergent, hybridizing species such as oaks and poplars provide models to identify genomic regions under selection and adaptive alleles that are transferred between species in hybrid zones.

Rootstock Evaluation for Grafted Cucumbers Grown in High Tunnels: Yield and Plant Growth

open access: yesHortScience, 2020
Grafting technology is increasingly being accepted in the United States, particularly for tomato (Solanum lycopersicum) production under protected structures. There is a great potential to expand this technology to other high tunnel crops. Using grafting

INTERSPECIFIC HYBRIDIZATION OF IMPATIENS [PDF]

open access: yesHortScience, 1992
An interspecific hybridization program involving five species of Impatiens was initiated to delineate incompatibility barriers. With the exception of one cross, no viable hybrid seed was recovered.

Investigation of some yield and fibre quality characteristics of interspecific hybrid (Gossypium hirsutum L.×G. barbadense L.) cotton varieties [PDF]

open access: yes, 2007
Interspecific hybrid cottons (Gossypium hirsutum L.xG. barbadense L.) have great both yield and quality potential. This study was conducted to determine potential yields and quality characteristics of hybrid cotton varieties in southeastern Anatolia ...

Interspecific Hybridization Between Cyclic Parthenogens [PDF]

open access: yesEvolution, 1985
Taxonomic work has suggested that interspecific hybrids are common in freshwater rotifers and cladocerans. Hybrids within the cladoceran genera Bosmina and Daphnia are apparently common in the large lakes of western Europe (Lieder 1956, 1983a, 1983b; Einsle, 1966, 1978).

CRISPR/Cas inactivation of RECQ4 increases homeologous crossovers in an interspecific tomato hybrid [PDF]

open access: yes, 2020
Crossover formation during meiosis in plants is required for proper chromosome segregation and is essential for crop breeding as it allows an (optimal) combination of traits by mixing parental alleles on each chromosome.

Analysis of the possible cytogenetic mechanism for overcoming hybrid lethality in an interspecific cross between Nicotiana suaveolens and Nicotiana tabacum

open access: yesScientific Reports, 2021
Hybrid lethality is a type of reproductive isolation in which hybrids die before maturation, due to the interaction between the two causative genes derived from each of the hybrid parents.

Introduction : extent, processes and evolutionary impact of interspecific hybridization in animals [PDF]

open access: yes, 2008
Since the time of Charles Darwin, studies of interspecific hybridization have been a major focus for evolutionary biologists. Although this phenomenon has often been viewed as problematic in the fields of ecology, taxonomy and systematics, it has become ...

The effect of temperature on seed quality and quantity in crosses between European (Populus tremula) and hybrid aspens (P. tremula x P. tremuloides)

open access: yesSilva Fennica, 2012
Hybrid aspen (Populus tremula L. Populus tremuloides Michx.) plantations are expanding in Fennoscandia and the Baltic countries; however, the possible effects of plantations on the native European aspen (P.
