Open‐land‐derived agroforestry and effects of abandonment of management of the main crop on ecosystem services and woody plant diversity

PLANTS, PEOPLE, PLANET, EarlyView.
Tropical forests are rapidly declining. One promising strategy to reverse the loss of tropical forest is the establishment of agroforestry on open land. We combined interviews with biodiversity surveys to learn general lessons from success and nonsuccess stories of the establishment of open‐land‐derived coffee agroforests in one of the world's ...

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).

Unexpected Dual Function of Plant YUCCA Enzymes Links Chlorophyll Catabolism to Auxin Homeostasis

Angewandte Chemie, Volume 138, Issue 9, 23 February 2026.
YUCCA enzymes are well known to catalyze the main step of auxin biosynthesis in plants. Here, a hitherto undescribed dual function was discovered, revealing that some YUCCAs also act in chlorophyll degradation. In vitro feedback regulation furthermore suggests a link between chlorophyll degradation and hormone homeostasis and a physiological role of ...

Climate requirements for cultivated Liberica coffee (Coffea liberica) and consequences for its use and development as a crop species

PLANTS, PEOPLE, PLANET, EarlyView.
The global coffee industry, supporting 25 million smallholder farmers, is vulnerable to climate change. Diversifying the coffee species portfolio beyond Arabica and robusta is a promising intervention. Liberica coffee could provide adaptive capacity, although its climate parameters for cultivation are poorly known.

Effect of Dormancy Treatment on Germination of Arabica Coffee ( Coffea arabica L.)

JURNAL AGROTEKNOLOGI, 2022
The germination process of arabica coffee bean takes a fairly longtime, due to semi-permeable skin against water. Dormancy treatment needs to improve germination rate of coffee beans before planting. The research was conducted at The Compost Centre of Agriculture Faculty, University of Sumatera Utara from July – September 2018 using a Randomized ...

Control failure risk, resistance and enzymatic activity of neurotoxic insecticides in Brazilian populations of Leucoptera coffeella (Lepidoptera: Lyonetiidae)

Pest Management Science, EarlyView.
Bioassays of 36 Leucoptera coffeella populations revealed resistance to neurotoxic insecticides, control failures of ≤62.9% and enzyme activity variation, with particularly high GST and low AChE levels. Abstract Background Leucoptera coffeella is a key pest of coffee crops in Brazil, causing significant damage by mining coffee leaves.
