Human influence on the distribution of cacao: insights from remote sensing and biogeography.
Cacao ( , Malvaceae) is an important tree crop in Africa and in the Americas. Current genomic evidence suggests that its original range in Tropical Americas was smaller than its current distribution and that human-mediated dispersal occurred before European colonization. This includes regions like Mesoamerica and Eastern Amazonia where cacao... -

Adaptation and the Geographic Spread of Crop Species.
Crops are plant species that were domesticated starting about 11,000 years ago from several centers of origin, most prominently the Fertile Crescent, East Asia, and Mesoamerica. From their domestication centers, these crops spread across the globe and had to adapt to differing environments as a result of this dispersal. We...Gutaker, Rafal M. ; Purugganan, Michael D.

Domestication of the Amazonian fruit tree cupuaçu may have stretched over the past 8000 years.
Amazonia, one of the largest and most biodiverse ecosystems on Earth, is a significant yet less-known arena for ancient plant domestication. Here, we traced the origins of ( ), an Amazonian tree crop closely related to cacao ( ), cherished for its flavorful seed-pulp, by employing an extensive genomic analysis... -

The causal mutation leading to sweetness in modern white lupin cultivars.
Lupins are high-protein crops that are rapidly gaining interest as hardy alternatives to soybean; however, they accumulate antinutritional alkaloids of the quinolizidine type (QAs). Lupin domestication was enabled by the discovery of genetic loci conferring low QA levels (sweetness), but the precise identity of the underlying genes remains uncertain. We... -

Genome Sequencing of up to 6,000-Year-Old Citrullus Seeds Reveals Use of a Bitter-Fleshed Species Prior to Watermelon Domestication.
Iconographic evidence from Egypt suggests that watermelon pulp was consumed there as a dessert by 4,360 BP. Earlier archaeobotanical evidence comes from seeds from Neolithic settlements in Libya, but whether these were watermelons with sweet pulp or other forms is unknown. We generated genome sequences from 6,000- and 3,300-year-old seeds... -

A chromosome-level genome of a Kordofan melon illuminates the origin of domesticated watermelons.
Wild progenitors of crops are important resources for breeding and for understanding domestication, but identifying them is difficult. Using an integrative approach, we discovered that a Sudanese form of melon with nonbitter whitish pulp, known as the Kordofan melon, is the closest relative of domesticated watermelons and a possible progenitor.... -

Phenotypic characterisation and linkage mapping of domestication syndrome traits in yellow lupin (Lupinus luteus L.).
The transformation of wild plants into domesticated crops usually modifies a common set of characters referred to as ‘domestication syndrome’ traits such as the loss of pod shattering/seed dehiscence, loss of seed dormancy, reduced anti-nutritional compounds and changes in growth habit, phenology, flower and seed colour. Understanding the genetic control...Iqbal, Muhammad Munir ; Erskine, William ; Berger, Jens D. ; Nelson, Matthew N.
