The role of tetraploids in the sexual-asexual cycle in dandelions (Taraxacum)

Apomictic plants often produce pollen that can function in crosses with related sexuals. Moreover, facultative apomicts can produce some sexual offspring. In dandelions, Taraxacum, a sexual-asexual cycle between diploid sexuals and triploid apomicts, has

The need for manual curation of the cotton proteome leads to a solution primed for undergraduate involvement

PLANTS, PEOPLE, PLANET, EarlyView.
Cotton is a global crop cultivated worldwide, yet a significant portion of the cotton genome remains functionally unannotated. Attempts have been made to automate this annotation but have been unable to completely bridge the gap. Human curation is still needed for accurate interpretations and predictions to be made.

Exploring Polyploidization in Nigella sativa L.: An Applicable Strategy Towards Crop Improvement

Horticulturae
A plant breeding program needs helpful markers, especially morphological ones, which can allow breeders to dispense with other markers, including cytological traits and flow cytometry. These markers can assist plant breeders in distinguishing diploid and

From knowledge to action: the importance of characterizing herbicide resistance mechanisms for implementing management strategies

Pest Management Science, EarlyView.
This review bridges the gap between understanding resistance mechanisms and applying them in weed management, highlighting how mechanistic insights reveal vulnerabilities that can guide more effective control strategies. Abstract Herbicide resistance remains one of the most intensively studied areas in weed science because of its direct consequences ...

Agronomic evaluation of AABB wheat tetraploids extracted from wheat neo-allohexaploids

, 2018
In order to understand if the mechanisms leading to stabilization of hexaploid wheats occurred in early generations after hybridization or accumulated slowly over the evolutionary course, we extracted tetraploids from newly synthesized allohexaploid ...

Induction, Identification, and Characterization of Tetraploids in Japanese Privet (Ligustrum japonicum)

, 2016
A number of privet species (Ligustrum spp.) that are important to the nursery and landscape industry have escaped cultivation and become invasive or weedy in the United States and other countries.

A Tetraploid Gerbera1

HortScience, 1972
Abstract A tetraploid of Gerbera jamesonii Bolus ex Hook, obtained from colchicine treatment of seed is characterized by increased vegetative and flower size. The tetraploid plant is fertile and produces tetraploid seedlings following self-pollination.

Inhibin βB Mediates Oligotrophic Adaptation via Regulating Muscle Satellite Cell Proliferation and Differentiation in Schizopygopsis younghusbandi

Integrative Zoology, EarlyView.
① Nutrient deficiency upregulates inhibin βB, activating SMAD signaling to promote p21. Increased p21 inhibits mcm2/mcm4/mcm5 and cyclin E2, inducing G1‐phase arrest, slowing growth, and reducing energy consumption. ② Inhibin βB also upregulates pdgf‐c, which induces α‐SMA, leading to muscle satellite cell fibrosis.

Increased phenotypic plasticity to climate may have boosted the invasion success of polyploid Centaurea stoebe.

PLoS ONE, 2012
Phenotypic plasticity may allow organisms to cope with altered environmental conditions as e.g. after the introduction into a new range. In particular polyploid organisms, containing more than two sets of chromosomes, may show high levels of plasticity ...

The Late Agricultural Development of Central Arabian Oases—Archaeobotanical and Archaeozoological Studies of the al‐Kharj Oasis

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT While oasis settlements emerged during the Bronze Age in Eastern and Northern Arabia, the settlement process in Central Arabia was different. Excavations at al‐Yamāma—main ancient settlement of the al‐Kharj oasis (Riyadh Province, KSA)—suggest that the latter did not emerge before the second half of the first millennium BCE.
