Evaluating the Adapt‐N model for dynamic nitrogen recommendation in Brazilian maize (Zea mays L.) systems

open access: yesAgronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract Several nitrogen rate recommendation methods have been developed to help farmers fertilize close to the economic optimum N rate (EONR). The objectives of this study were to (i) evaluate a dynamic method (Adapt‐N) for N rate recommendations for maize (Zea mays L.) in Brazil relative to EONRs determined specifically for each trial and (ii ...

Homoisoflavonoids—From Natural Specificity and Biosynthesis to Precision Health‐Promoting Mechanisms

open access: yesFood Frontiers, Volume 7, Issue 3, May 2026.
Homoisoflavonoids are rare flavonoids with a unique bi‐aromatic oxygen‐heterocyclic structure. This review synthesizes their structure–activity relationships in anti‐inflammatory, hypoglycemic, and anticancer contexts. By highlighting their specific natural distribution and outlining biosynthetic pathways, it provides a conceptual framework and ...

Preliminary Functional Group Patterns of Arthropods in a Maize Field and Adjacent Cultivated Refuge Strip in South Africa

open access: yesAustral Entomology, Volume 65, Issue 2, May 2026.
ABSTRACT Agricultural intensification is a major driver of global arthropod declines. Habitat management strategies, such as cultivated refuge strips (CRS), can counteract these effects by enhancing biodiversity, promoting conservation biological control and improving agroecosystem resilience.

A First Quantification of Plant Endemism in the Manica Highlands (Zimbabwe–Mozambique) and the Significance of Open Habitats

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
We present here the first quantitative assessment of plant endemics from the Manica Highlands (Zimbabwe‐Mozambique), totalling 216 taxa, representing over 9% of the estimated total flora. A major finding is that 173 (80%) endemic taxa are principally or entirely confined to open montane habitats such as grassland, bare rock, crags and scrub or dwarf ...

Convergence and parallelism in the evolution of plant metabolism

open access: yesJournal of Integrative Plant Biology, Volume 68, Issue 4, Page 1013-1031, April 2026.
Similar traits in different organisms may originate from shared ancestry or evolve independently. The terminology used to define phenotypic similarity is often confusing. This review attempts to clarify the definitions and present examples from plant domestication and specialized metabolism to explain how complex traits evolve repeatedly in plants ...

Structural Quality of an Ultisol Under Long‐Term Different Tillage Systems and Cover Crops With Corn in Northeast Brazil

open access: yesSoil Use and Management, Volume 42, Issue 2, April‐June 2026.
ABSTRACT Dual‐purpose corn cropping is a widespread and economically important agricultural activity in Brazilian rural areas. The objective of this work was to study the structural quality of a dystrophic Red‐Yellow Ultisol under different tillage systems, previous crops and inoculant treatments, and its relationship with corn yield.

Mitogenomic phylogeny of Eurytoma Illiger (Hymenoptera: Eurytomidae): Genus delimitation, species‐group assessment and recurrent host‐use transitions

open access: yesSystematic Entomology, Volume 51, Issue 2, April‐June 2026.
Mitogenomes from 166 Eurytomidae confirm Eurytoma is polyphyletic; 10 species groups are recovered in Eurytoma s.s., and several lineages are reassigned to other genera or newly delimited clades. Conservative head and mesosoma traits, especially the postgenal depression and ventral shelf, track mitogenomic clades closely, supporting their diagnostic ...

Cytogenetics of Crotalaria. I. Mitotic complements in twenty species of Crotalaria L.

open access: yesCYTOLOGIA, 1979
Detailed karyotype studies have been undertaken in 20 species. Some of them have been investigated for the first time. Nineteen species have the mitotic complement of 16 chromosomes, while in C. incana it is 14. There is no clearcut size differences among the chromosomes.
