How and why do species break a developmental trade‐off? Elucidating the association of trichomes and stomata across species

American Journal of Botany, Volume 111, Issue 5, May 2024.
Abstract Premise Previous studies have suggested a trade‐off between trichome density (Dt) and stomatal density (Ds) due to shared cell precursors. We clarified how, when, and why this developmental trade‐off may be overcome across species. Methods We derived equations to determine the developmental basis for Dt and Ds in trichome and stomatal indices (

Germination and Emergence of Digitaria insularis (L.) Fedde Susceptible and Resistant to Glyphosate

Journal of Experimental Agriculture International, 2019
To Know the behavior shown in seed germination and emergence of Digitaria insularis (L.) Fedde enables develop strategies to reduce the seed bank in cultivated areas. The aim of this research was to evaluate the germination and emergence of weed biotypes of D. insularis susceptible and resistant to glyphosate in two substrates. The experiment was

Pest categorisation of Pyrrhoderma noxium

EFSA Journal, Volume 22, Issue 3, March 2024.
Abstract Following the commodity risk assessment of bonsai plants (Pinus parviflora grafted on Pinus thunbergii) from China performed by EFSA, the EFSA Plant Health Panel performed a pest categorisation of Pyrrhoderma noxium, a clearly defined plant pathogenic basidiomycete fungus of the order Hymenochaetales and the family Hymenochaetaceae.

Interference periods of sourgrass (Digitaria insularis) on maize crop

Australian Journal of Crop Science
Sourgrass (Digitaria insularis (L.) Fedde) is frequently reported as one of the main weeds in grain production, along with several reports of herbicide resistance. The objectives of this study were (1) to understand the length of time that the maize crop, cv. P4285VYHR PIONEER could coexist with a weed community dominated by D. insularis plants without

Floristic diversity of patches generated by protected Ficus ‘trees outside forests’ in agricultural landscapes in Madagascar

African Journal of Ecology, Volume 62, Issue 2, February 2024.
Abstract Ficus trees play an important role as key species in both ecological and sociocultural networks in Madagascar. This study focused on species of isolated Ficus growing in agricultural areas adjoining a forest corridor linking the Ranomafana and Andringitra National Parks in east‐central Madagascar, with the aim of understanding the structural ...

Morphophysiological and nutritional responses in maize hybrids competing with Digitaria insularis

Revista Caatinga
ABSTRACT This study aimed to evaluate the competitive interaction between maize hybrids in the presence of Digitaria insularis through experiments in a series of substitutions. The experiments were conducted in a randomized block design with four replicates. Six maize hybrids were used, and the plant density of maize and D.

Efficacy of imazapic/imazapyr and other herbicides in mixtures for the control of Digitaria insularis prior to soybean sowing

Agronomía Colombiana, 2020
Herbicide mixtures, use of multiple sites of action, and other weed management practices are necessary to avoid cases of biotype resistance. The aim of this study was to evaluate the efficiency of imazapic/imazapyr and other herbicides in mixtures to ...

In vitro acaricide and anticholinesterase activities of digitaria insularis (Poaceae) against Rhipicephalus (Boophilus) microplus

Veterinary Parasitology, 2018
Medicinal plants have been proposed as an alternative for acaricide control, aiming to develop lower-cost and eco-friendly ectoparasiticide products. The aim of this study was to evaluate the in vitro activity of the extracts and fractions obtained from the leaves of Digitaria insularis on the reproductive efficacy of the bovine tick Rhipicephalus ...

EPSPS variability, gene expression, and enzymatic activity in glyphosate-resistant biotypes of Digitaria insularis

Genetics and Molecular Research, 2016
Weed resistance to herbicides is a natural phenomenon that exerts selection on individuals in a population. In Brazil, glyphosate resistance was recently detected in Digitaria insularis. The objective of this study was to elucidate mechanisms of weed resistance in this plant, including genetic variability, allelism, amino acid substitutions, gene ...
