PEK14: A Kinesin‐4 Necessary for Male‐Derived Fertility in Arabidopsis thaliana

Cytoskeleton, EarlyView.
ABSTRACT Of the 61 kinesins annotated in Arabidopsis thaliana, many are still without assigned function. Here, we have screened an insertional mutant library of Arabidopsis pollen‐expressed kinesins for fertility defects. Insertional mutants for three kinesins showed a significant reduction in seed set.

Generalist‐pollinated Arabis alpina exhibits floral scent variation at multiple scales

Nordic Journal of Botany, EarlyView.
Plants that depend on animals for reproduction often use complex floral traits to attract pollinators. Floral scent is recognized as part of the pollinator attraction module and can be shaped by plant‐pollinator interactions. In recent decades, research has started to reveal the dynamic properties of floral scent, identifying patterns of spatial and ...

Epigenetic control on transcription of vernalization genes and whole-genome gene expression profile induced by vernalization in common wheat

Plant Diversity
Vernalization is necessary for winter wheat to flower. However, it is unclear whether vernalization is also required for spring wheat, which is frequently sown in fall, and what molecular mechanisms underlie the vernalization response in wheat varieties.

Development and adoption of Kernza—A perennial grain crop for sustainable agriculture

PLANTS, PEOPLE, PLANET, EarlyView.
Annual cereal grains account for ~50% of human food calories, but cultivation of these crops has resulted in major environmental and social issues worldwide. For nearly three decades, researchers have been breeding intermediate wheatgrass—a perennial cool‐season grass—to serve as the world's first commercial‐scale perennial grain crop to improve ...

Major-effect alleles at relatively few loci underlie distinct vernalization and flowering variation in Arabidopsis accessions. [PDF]

PLoS ONE, 2011
We have explored the genetic basis of variation in vernalization requirement and response in Arabidopsis accessions, selected on the basis of their phenotypic distinctiveness.

Cameras do not always take a full picture: wolf activity patterns revealed by accelerometers versus road‐positioned camera traps

Remote Sensing in Ecology and Conservation, EarlyView.
Camera traps have become an increasingly popular non‐invasive alternative to animal‐attached devices for studying wildlife behaviour. This study compared wolf (Canis lupus) activity patterns derived from collar accelerometers and road‐positioned camera traps and revealed strong overall agreement but also important seasonal and diel mismatches between ...

Temperature and Photoperiod Change the Flowering Process in Prunella vulgaris by Inducing Changes in Morphology, Endogenous Hormones, Carbon/Nitrogen Metabolites, and Gene Expression

Journal of the American Society for Horticultural Science, 2022
The spicas of Prunella vulgaris are widely used in the medical, beverage, and ornamental fields. Temperature and photoperiod are the two main ecological factors that determine the transformation of many plants from vegetative growth to reproductive ...

Attainment of reproductive competence, phase transition, and quantification of juvenility in mutant genetic screens [PDF]

, 2014
Plant development between seedling emergence and flowering is characterized by a series of successive qualitative phases: (1) a post embryonic photoperiodinsensitive phase, during which plants are insensitive to photoperiod; (2) a photoperiod ...

Vernal ulcer.

Indian journal of ophthalmology, 1990
Vernal ulcer is a rare entity not reported in Indian ophthalmic literature. 76 patients in the age group ranging from 3-43 years diagnosed as having vernal conjunctivitis had been referred from general ophthalmology clinic to cornea service of the same institute during 1988-89. Among them 60 were males and 16 were females.
