The Formation Mechanism and Resulting Properties of Brown Dwarfs [PDF]

Symposium - International Astronomical Union, 2003
We present results from the most complex hydrodynamical star formation calculation performed to date. It follows the collapse and fragmentation of a large-scale turbulent molecular cloud to form dozens of stars and brown dwarfs. It resolves all fragmentation down to the opacity limit, binary stars with separations as small as 1 AU, and circumstellar ...

Targeted Metabolic and Transcriptomic Analysis of Pinus yunnanensis var. pygmaea with Loss of Apical Dominance

Current Issues in Molecular Biology, 2022
Pinus yunnanensis var. pygmaea demonstrates obvious loss of apical dominance, inconspicuous main trunk, which can be used as an ideal material for dwarfing rootstocks. In order to find out the reasons for the lack of apical dominance of P.

An evaluation of genotyping by sequencing (GBS) to map the Breviaristatum-e (ari-e) locus in cultivated barley [PDF]

, 2014
We explored the use of genotyping by sequencing (GBS) on a recombinant inbred line population (GPMx) derived from a cross between the two-rowed barley cultivar 'Golden Promise' (ari-e.GP/Vrs1) and the six-rowed cultivar 'Morex' (Ari-e/vrs1) to map plant ...

Dwarfing and the Underlying Morphological Changes of Poa alpigena Plants in Response to Overgrazing Conditions

Plants, 2022
Poa alpigena is a dominant grass species in alpine meadows, which is sensitive to environmental conditions. In this study, we analyzed the characteristics of the anatomical structure of the stems and leaves of Poa alpigena in overgrazed and enclosed ...

A unique defense mechanism against anthrax demonstrated in dwarf swine [PDF]

Journal of Bacteriology, 1967
Abstract : A unique defense mechanism against Bacillus anthracis was demonstrated by the Pitman-Moore variety of dwarf swine. A large percentage of spores failed to germinate in vivo when massive doses were administered via either the respiratory or intraperitoneal route. Only spores with no apparent outgrowth of vegetative cells could be cultured from

Differential transcription pathways associated with rootstock-induced dwarfing in breadfruit (Artocarpus altilis) scions

BMC Plant Biology, 2021
Background Breadfruit (Artocarpus altilis) is a traditional staple tree crop throughout the tropics. Through interspecific grafting, a dwarf phenotype with over 50% reduction in plant height was identified when marang (Artocarpus odoratissimus ...

ON THE EFFICIENCY OF THE TIDAL STIRRING MECHANISM FOR THE ORIGIN OF DWARF SPHEROIDALS: DEPENDENCE ON THE ORBITAL AND STRUCTURAL PARAMETERS OF THE PROGENITOR DISKY DWARFS [PDF]

The Astrophysical Journal, 2010
The tidal stirring model posits the formation of dSph galaxies via the tidal interactions between rotationally-supported dwarfs and MW-sized host galaxies. Using a set of collisionless N-body simulations, we investigate the efficiency of the tidal stirring mechanism.

Analysis of a radiation-induced dwarf mutant of a warm-season turf grass reveals potential mechanisms involved in the dwarfing mutant [PDF]

Scientific Reports, 2020
AbstractZoysia matrella [L.] Merr. is a widely cultivated warm-season turf grass in subtropical and tropical areas. Dwarf varieties of Z. matrella are attractive to growers because they often reduce lawn mowing frequencies. In this study, we describe a dwarf mutant of Z. matrella induced from the 60Co-γ-irradiated calluses.

Genome-wide alternative polyadenylation dynamics underlying plant growth retardant-induced dwarfing of pomegranate

Frontiers in Plant Science, 2023
Dwarfed stature is a desired agronomic trait for pomegranate (Punica granatum L.), with its advantages such as lower cost and increased yield. A comprehensive understanding of regulatory mechanisms underlying the growth repression would provide a genetic

Transcriptome profiling provides insights into molecular mechanism in Peanut semi-dwarf mutant [PDF]

BMC Genomics, 2020
Abstract Background Plant height, mainly decided by main stem height, is the major agronomic trait and closely correlated to crop yield. A number of studies had been conducted on model plants and crops to understand the molecular and genetic basis of plant height.
