Induction to tetraploidy in catarina scallop, Argopecten ventricosus (Sowerby II, 1842)
Ciencias Marinas, 2003 Induction to tetraploidy by inhibition of the first polar body and first cellular division in fertilized eggs from diploids produced an occasional small percentage of tetraploid D-larvae, but was not successful in multiple experiments with individual ...

Systemic bio‐inequity links poverty to biodiversity and induces a conservation paradox
People and Nature, EarlyView.Abstract Biodiversity is declining globally while inequity is growing, and poverty rates are not improving. Global sustainable development and conservation initiatives aim to address biodiversity loss and poverty simultaneously. Through text analysis of global biodiversity policies, we identified a consistent narrative that countries with high ...

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

TETRAPLOID WATERMELON PRODUCTION [PDF]
Egyptian Journal of Agricultural Research, 2012 Tetraploids are desired to produce seedless fruits. In order to produce an autotetraploid population in watermelon (Citrullus lanatus Thunb) by colchicine. four treatment methods were examined ( dry seeds, soaking of germinated seeds and the meristem tip of the seedlings at the emergence of two true type leaves beside the control treatment ) to ...

Past, present and future of local crop evolution
PLANTS, PEOPLE, PLANET, EarlyView.Promoting agrobiodiversity is a promising strategy for mitigating the negative effects of climate change on global food security. We highlight the central role evolutionary processes play in harnessing the potential of local crops by integrating genomics, archaeology, ethnobotany and traditional ecological knowledge (TEK).

Gene turnover in the common ancestor of all C4 grasses
PLANTS, PEOPLE, PLANET, EarlyView.Understanding how plants evolve more efficient photosynthesis is important in a warming world where improving crop productivity and resilience is a global priority. By generating the first reference genomes for an early‐diverging group of grasses called the Aristidoideae, we were able to reconstruct the genetic makeup of the last common ancestor of all
