From wild to tamed: Reimagining novel crops through omics and local plant diversity

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
The global food system faces growing pressure from climate change, biodiversity loss, and rising nutritional demands. Agriculture has increased yields but reduced crop diversity, flavor, and nutritional quality, leaving societies vulnerable and dependent on a narrow set of staple species.

Pollen Developmental Arrest: Maintaining Pollen Fertility in a World With a Changing Climate

open access: yesFrontiers in Plant Science, 2019
During evolution of land plants, the haploid gametophytic stage has been strongly reduced in size and the diploid sporophytic phase has become the dominant growth form.

Synthetic polymer nanocarrier enhances dsRNA stability but not RNAi efficacy in Brassicogethes aeneus

open access: yesPest Management Science, EarlyView.
Experimental setup for dsRNA feeding in Brassicogethes aeneus to evaluate the effect of a synthetic polymer nanocarrier on RNAi efficiency. The experiment assessed whether the nanocarrier enhances RNAi after oral dsRNA delivery. (a) Stability of dsRNA–nanocarrier complexes was tested in simulated gut conditions. (b) Gene expression of αCOP and dre4 was

Fitness costs associated with Vip3Aa resistance on various hosts in Helicoverpa zea

open access: yesPest Management Science, EarlyView.
Significant fitness costs associated with Vip3Aa resistance in H. zea were observed across three non‐Bt hosts. Abundant non‐Bt refuges could help limit the spread of Vip3Aa resistance in H. zea in the field. Abstract BACKGROUND Transgenic crops containing Bacillus thuringiensis (Bt) proteins are crucial for managing major agricultural pests such as the

Chitosan‐protected dsRNA increases efficacy against Helicoverpa armigera without compromising biosafety for pollinators

open access: yesPest Management Science, EarlyView.
Chitosan/tripolyphosphate/double‐stranded RNA (dsRNA) nanoparticles enhance RNA interference efficacy of orally delivered dsRNA against Helicoverpa armigera. Nanoparticles reduce the LC50 and do not cause deleterious effects or toxicity on beneficial insects.

Stigma Receptivity And Pollen Viability of Melaleuca alternifolia

open access: yesIndonesian Journal of Forestry Research, 2009
Stigma  receptivity based on seed set and pollen  tubes growth  following controlled pollination of flowers  of different  ages was examined  in Melaleuca alternifolia . The stigma secretion during 10 days after anthesis and pollen viability under three different temperatures and five storage times were also observed .

Evaluating astigmatid mites as supplemental food for Macrolophus pygmaeus: contrasting responses between commercial and wild populations

open access: yesPest Management Science, EarlyView.
Astigmatid mites provide low‐cost supplemental food for Macrolophus pygmaeus, supporting survival and development, with population‐specific responses and Acarus siro and Carpoglyphus lactis as the most promising alternatives. Abstract BACKGROUND Early establishment of Macrolophus pygmaeus in crops depends on the availability of supplemental food ...

Bt agave: why it is time to explore a new biotechnological frontier

open access: yesPest Management Science, EarlyView.
Drylands cover 41% of Earth, requiring sustainable crops. Agave, drought‐ and heat‐adapted, offers high‐value products with low water needs. Pests limit yield, yet Bacillus thuringiensis (Bt) Cry proteins, successful in other plants, remain unexploited in Agave.

Pollen morphology and viability relates to seed productionin hybrid roses

open access: yes, 2013
To avoid the risk of very low seed production, the estimation of the pollen fertility is the reliable tool. In the present study nine hybrid rose genotypes were evaluated for their pollen viability and fertility status in vitro.

Disease control in oilseed rape: Current insights and perspectives for next‐generation integrated pest management

open access: yesPest Management Science, EarlyView.
Winter oilseed rape in Europe suffers frequent pathogen losses. This review outlines key integrated pest management (IPM) strategies, rotation, residue and tillage management, optimized sowing, resistance, and targeted fungicides supported by forecasting.
