In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle. [PDF]

Conserv Biol
Abstract Current plant conservation efforts are hindered by, for example, poor seed germination, low viability, and insufficient propagation and preservation technologies. To address these problems, we devised an approach to plant conservation that integrates conservation, preservation, and restoration (CPR), which uses advanced in vitro techniques. We

Evidence of fruit syndromes in the recently diverged wild tomato clade opens new possibilities for the study of fleshy fruit evolution

PLANTS, PEOPLE, PLANET, Volume 5, Issue 6, Page 948-962, November 2023., 2023
Fleshy fruits provide humans with many flavorful and nutritious crops. Understanding the diversity of these plants is fundamental to managing agriculture and food security in a changing world. This study surveyed fruit trait variation across species of tomato wild relatives and explored associations among color, size, shape, sugars, and acids.

Cytokinin activity – transport and homeostasis at the whole plant, cell, and subcellular levels

New Phytologist, Volume 239, Issue 5, Page 1603-1608, September 2023., 2023
Summary Cytokinins (CKs) are important plant hormones that regulate a variety of biological processes implicated in plant development and stress responses. Here, we summarize the most recent advances in discovering and characterizing the membrane transporters involved in long‐ and short‐distance translocation of CKs and their significance in CK signal ...

Multiple compensatory mutations contribute to the de‐domestication of Iberian weedy rice

PLANTS, PEOPLE, PLANET, Volume 4, Issue 5, Page 499-510, September 2022., 2022
Weedy plants are a major constraint on agricultural productivity. Weedy rice, a weedy type of rice, invades rice fields worldwide and is responsible for reductions in rice yields. Studies to date have detected multiple independent weedy rice origins in different parts of the world.

Integrating effects of neighbor interactions for pollination and abiotic resources on coffee yield in a multi‐strata agroforest

Biotropica, Volume 54, Issue 5, Page 1226-1237, September 2022., 2022
Animal‐pollinated plants interact with neighbors for both abiotic resources and pollination, but few studies have compared the relative magnitude of these effects, particularly in agroecosystems. This study evaluated the effects of neighboring plants at three vertical strata (herbs, coffee bushes, and canopy trees) on pollen deposition, fertilization ...
