A new species of Drimia Jacq. ex Willd. (Asparagaceae) from Nellai wildlife sanctuary, Western Ghats, India

open access: yesNordic Journal of Botany, EarlyView.
The new species Drimia courtallensis from the Nellai Wildlife Sanctuary of Tamil Nadu, India is described and illustrated. It is similar to Drimia razii,in its necked bulb, hysteranthous nature, lax inflorescence and diurnal flowers on moderately short pedicels but it can be distinguished by its broader linear‐lanceolate leaves (230–420 × 6–15 mm ...

Friends or foes? Polyploidy and competition in a grassland geophyte

open access: yesOikos, EarlyView.
Previous studies have suggested polyploids may possess a competitive advantage over diploids, due to their larger size, increased vigour or ability to better respond to abiotic stress. However, few studies have tested the effect of polyploidy on competitive ability directly, and only relatively recently has this oversight begun to be addressed. Here we

Speciation with gene flow

open access: yesPLANTS, 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.

Wider geographic distribution and higher diversity of hexaploids than tetraploids in Carassius species complex reveal recurrent polyploidy effects on adaptive evolution

open access: yesScientific Reports, 2017
Polyploidy roles on adaptive evolution and ecological novelty have been extensively studied in plants but remained unclear in vertebrates owing to the rare polyploidy incidences.

Integrative analyses of targeted metabolome and transcriptome of Isatidis Radix autotetraploids highlighted key polyploidization-responsive regulators

open access: yesBMC Genomics, 2021
Background Isatidis Radix, the root of Isatis indigotica Fort. (Chinese woad) can produce a variety of efficacious compound with medicinal properties. The tetraploid I.

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

open access: yesPest 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 ...

Ecotoxicological Evaluation of the Antimicrobial Butylparaben in Edaphic Organisms Using Multiple Biomarkers

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Butylparaben (BuP) recurrently contaminates soils worldwide, mainly by incorporating sewage sludge into cultivated areas, using wastewater in irrigation, and leaching contaminated soils. However, there are few studies on the ecotoxicological effects of this paraben on edaphic organisms.

Creating insect neopolyploid lines to study animal polyploid evolution

open access: yesEvolutionary Applications
Whole‐genome duplication (polyploidy) poses many complications but is an important driver for eukaryotic evolution. To experimentally study how many challenges from the cellular (including gene expression) to the life history levels are overcome in ...

Brassica diversity through the lens of polyploidy: genomic evolution, introgression, and homoeologous exchange

open access: yesHorticultural Plant Journal
Polyploidy, or whole-genome duplication, is an important evolutionary process that has shaped the genomes and traits of many plants, including numerous important crops.
