Strategies to reduce the apical necrosis in vitro multiplication and rooting of Pistachio

open access: yesRevista Colombiana de Biotecnología, 2016
The pistachio (Pistacia sp.) is one of the least exploited fruit among the main causes is the high cost of plant material by the difficulties of propagation of the species.

Varied motivations for secondary forest reclearing among landholders make forest persistence challenging

open access: yesPeople and Nature, EarlyView.
Abstract Remote sensing studies show that ephemeral forest regeneration is widespread in the tropics, limiting the climate and biodiversity benefits from net increases in forest cover. Socioeconomic, biophysical and landscape variables can help explain the spatial distribution of reforestation reversals.

Plant regeneration of sweet acacia (Vachellia farnesiana [L.] Wight & Arn.) via somatic embryogenesis

open access: yesDiscover Forests
Vachellia farnesiana (L.) Wight & Arn. is a leguminous tree of ecological and economic value, yet its propagation is limited by seed dormancy and inefficient vegetative methods.

Repositories of biocultural diversity: Toward best practices for empowering ethnobotany in digital herbaria

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Societal Impact Statement As herbaria digitize millions of plant specimens, ethnobotanical information associated with them is becoming increasingly accessible. These biocultural data include plant uses, names, and/or management practices of Indigenous Peoples and Local Communities (IPLCs).

Cultivo protegido: aspectos microclimáticos.

open access: yesRevista Brasileira de Horticultura Ornamental, 1995
O cultivo de flores e hortaliças em ambientes protegidos é uma atividade que se encontra em franca expansão no Brasil. A principal vantagem dessa técnica consiste na possibilidade de produção nos períodos de entressafra, permitindo maior regularização da oferta e melhor qualidade dos produtos.

Engineering compact Physalis peruviana (goldenberry) to promote its potential as a global crop

open access: yesPLANTS, 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

Past, present and future of local crop evolution

open access: yesPLANTS, 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).
