Relações entre crescimento vegetativo e acúmulo de nitrogênio em duas cultivares de arroz com arquiteturas contrastantes The relationship between vegetative growth and nitrogen accumulation in two rice cultivars with contrasting architecture

Acta Botânica Brasílica, 2008
Foram estudados, mediante análise do crescimento, o acúmulo de biomassa e nitrogênio (N) e sua eficiência de utilização, durante o estádio de crescimento vegetativo, em duas cultivares de arroz (Oryza sativa L.) com arquiteturas contrastantes: IAC-4440 ...

Engineering compact Physalis peruviana (goldenberry) to promote its potential as a global crop

PLANTS, PEOPLE, PLANET, EarlyView.
Goldenberry (Physalis peruviana) produces sweet, nutritionally rich berries, yet like many minor crops, is cultivated in limited geographical regions and has not been a focus of breeding programs for trait enhancement. Leveraging knowledge of plant architecture‐related traits from related species, we used CRISPR/Cas9‐mediated gene editing to generate a

Variations of Histone Modification Patterns: Contributions of Inter-plant Variability and Technical Factors

Frontiers in Plant Science, 2017
Inter-individual variability of conspecific plants is governed by differences in their genetically determined growth and development traits, environmental conditions, and adaptive responses under epigenetic control involving histone post-translational ...

Speciation with gene flow

PLANTS, PEOPLE, PLANET, EarlyView.
Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.

Mutations in the PERIANTHIA gene of Arabidopsis specifically alter floral organ number and initiation pattern [PDF]

, 1996
An open question in developmental biology is how groups of dividing cells can generate specific numbers of segments or organs. We describe the phenotypic effects of mutations in PERIANTHIA, a gene specifically required for floral organ patterning in ...

Transport engineering as a strategy to realize rapeseed's potential as a protein‐rich food

Pest Management Science, EarlyView.
The heavily pesticide‐dependent rapeseed is an under‐utilized protein source for food owing to anti‐nutritional glucosinolates. Transport engineering technology may reduce glucosinolates in seeds while increasing defense in vegetative parts. Abstract Rapeseed is the world's second‐largest oilseed crop, and the low‐value press cake that remains after ...

Nontargeted biomonitoring of halogenated organic compounds in two ecotypes of bottlenose dolphins (Tursiops truncatus) from the Southern California Bight. [PDF]

, 2015
Targeted environmental monitoring reveals contamination by known chemicals, but may exclude potentially pervasive but unknown compounds. Marine mammals are sentinels of persistent and bioaccumulative contaminants due to their longevity and high trophic ...

Shewanella baltica Ecotypes Have Wide Transcriptional Variation under the Same Growth Conditions

mSphere, 2016
In bacterial populations, subtle expressional differences may promote ecological specialization through the formation of distinct ecotypes. In a barrier-free habitat, this process most likely precedes population divergence and may predict speciation ...

Fendioxypyracil, a new and systemic PPO‐inhibiting herbicide for X‐spectrum weed control

Pest Management Science, EarlyView.
This graphical abstract presents the discovery and synthesis of PPO herbicide structures with a central pyridine core, showing molecular conformations, dose–response inhibition curves for PPO1 and PPO2, and comparative weed and grass control efficacy of fendioxypyracil versus other herbicides in greenhouse and field trials.
