A shade‐hyposensitive tomato line shows altered auxin homeostasis and higher fruit yield under high‐density field conditions

open access: yesNew Phytologist, Volume 247, Issue 6, Page 2839-2851, September 2025.
Summary Plants detect the presence of nearby vegetation as a reduced ratio of red to far‐red light (low R : FR). This proximity shade signal can be simulated in the lab by supplementing white light (W) with FR (W + FR). While shade avoidance strategies are considered undesirable in agricultural crops, FR supplementation enhances plant growth and fruit ...

Toward a phylogenomic classification of magnoliids

open access: yesAmerican Journal of Botany, Volume 112, Issue 1, January 2025.
Abstract Premise Magnoliids are a strongly supported clade of angiosperms. Previous phylogenetic studies based primarily on analyses of a limited number of mostly plastid markers have led to the current classification of magnoliids into four orders and 18 families. However, uncertainty remains regarding the placement of several families.

Evidence for human‐caused founder effect in populations of Solanum jamesii at archaeological sites: II. Genetic sequencing establishes ancient transport across the Southwest USA

open access: yesAmerican Journal of Botany, Volume 111, Issue 7, July 2024.
Abstract Premise The domestication of wild plant species can begin with gathering and transport of propagules by Indigenous peoples. The effect on genomic composition, especially in clonal, self‐incompatible perennials would be instantaneous and drastic with respect to new, anthropogenic populations subsequently established.

Estrutura do pericarpo de Banisteriopsis C.B.Rob. e Diplopterys A.Juss. (Malpighiaceae): Novos dados suportando a segregação genérica

open access: yes, 2022
Molecular studies have indicated that some species of Banisteriopsis would be more appropriately placed in Diplopterys. Both of these genera are neotropical members of the Malpighiaceae, a family that is widely diverse in South America, especially in the Brazilian savanna (cerrado).

Evolutionary pathways to lower biomass allocation to the seed coat in crops: insights from allometric scaling

open access: yesNew Phytologist, Volume 243, Issue 1, Page 466-476, July 2024.
Summary Crops generally have seeds larger than their wild progenitors´ and with reduced dormancy. In wild plants, seed mass and allocation to the seed coat (a proxy for physical dormancy) scale allometrically so that larger seeds tend to allocate less to the coats. Larger seeds and lightweight coats might thus have evolved as correlated traits in crops.
