Effects of Atmospheric CO2 Levels on the Susceptibility of Maize to Diverse Pathogens

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Rising atmospheric CO2 has significant implications for crop productivity and food security. Based on studies in C3 plants, elevated CO2 (eCO2) can shape plant‐pathogen interactions, although the outcomes are often variable. The question of how eCO2 influences immunity and disease development in C4 plants, such as the globally important cereal

Identification of ‘Prata anã’ banana leaf to diagnose the level of phosphorus sufficiency

open access: yesRevista Brasileira de Fruticultura, 2018
The aim of this study was to identify the leaf and its part with greater sensitivity to detect P variation in the ‘Prata anã’ banana plant. The experiment was carried out in Montes Claros, Minas Gerais, in a clayey Oxisol.

Early‐stage diagnosis of nutrient deficiency by chlorophyll fluorescence in maize

open access: yesPlant Biology, EarlyView.
Symptomatic differences between nitrogen and magnesium deficiency in maize seedlings can be detected using chlorophyll fluorescence to measure spatiotemporal changes in leaf chlorophyll and epidermal UV‐absorbing compounds for early diagnosis and differentiation of nutrients.

Phenotyping Common Bean (Phaseolus vulgaris L.) Tolerance to Fomesafen and Imazamox Using Visible RGB Imaging Integrated With Multivariate Analysis

open access: yesLegume Science, Volume 8, Issue 3, September 2026.
ABSTRACT The common bean is vital for food security, but its productivity is often limited by competition with weeds, requiring the use of herbicides. The response of genotypes to herbicides such as fomesafen and imazamox is variable, and the traditional evaluation of phytotoxicity through visual methods is subjective.

Lack of Hydraulic Acclimation in Response to Multiple Droughts and Recovery

open access: yesPlant, Cell &Environment, Volume 49, Issue 9, Page 6931-6943, September 2026.
ABSTRACT Human‐caused climate change is expected to bring more frequent and extended droughts with shorter wet periods of relief in between for many regions of the world. Critical knowledge gaps remain around the extent to which tree species can acclimate physiologically to repeated droughts.

Interaction Between Nitrogen Forms, Phosphorus Forms, and Mineral Phases Drives Phosphorus Limitation and Uptake by Ryegrass in a Model System

open access: yesJournal of Plant Nutrition and Soil Science, Volume 189, Issue 4, Page 593-604, August 2026.
Nitrogen addition shifts plant nutrition from nitrogen to phosphorus (P) limitation. Nitrate‐based nitrogen enhances P acquisition more effectively than ammonium through increased phosphatase activity, independently of pH changes. Organic P forms induce stronger P limitation than inorganic P.

Testing and validation of methods for the diagnosis and recomendation integrated system for Signal grass

open access: yesScientia Agricola, 2005
The Diagnosis and Recommendation Integrated System (DRIS) allows the interpretation of results of leaf analysis through relationships among nutrients, instead of the absolute and isolated concentration of each one, as it is used by the criterion of ...

Taxonomic reappraisal of the mangrove genus Avicennia (Acanthaceae) in India

open access: yesNordic Journal of Botany, Volume 2026, Issue 8, August 2026.
A taxonomic reappraisal of the mangrove genus Avicennia in India was undertaken through extensive field surveys and critical examination of herbarium specimens. Three taxa, Avicennia alba, Avicennia marina subsp. marina, and Avicennia officinalis, are described in detail. A synonymic list was compiled using the World Checklist of Vascular Plants (WCVP)

Distribution and Occurrence of Cercospora Leaf Spot of Mungbean (Vigna radiata) and Associated Agronomic Factors in Ethiopia

open access: yesPlant-Environment Interactions, Volume 7, Issue 4, August 2026.
ABSTRACT Mungbean (Vigna radiata L. Wilczek) is a major cash‐generating pulse crop in Ethiopia's lowlands, serving as a key source of plant‐based protein and contributing to soil fertility. However, its production is severely constrained by Cercospora Leaf Spot (CLS), a destructive fungal disease.
