Boron deficiency responses in maize (Zea mays L.) roots

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView., 2023
Abstract Background Boron (B) is an essential micronutrient for plants. Dicot plants respond to insufficient B supply by altering root architecture and root hair growth. How root systems of rather low‐B demanding monocot species such as maize (Zea mays L.) respond to B deficiency in terra has not been experimentally resolved, yet.

Addition of nocturnal pollinators modifies the structure of pollination networks

open access: yesScientific Reports
AbstractAlthough the ecological network approach has substantially contributed to the study of plant-pollinator interactions, current understanding of their functional structure is biased towards diurnal pollinators. Nocturnal pollinators have been systematically ignored despite the publication of several studies that have tried to alleviate this ...

Exploring Chemical Variability in the Essential Oil of Artemisia absinthium L. in Relation to Different Phenological Stages and Geographical Location

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT The plant essential oils (EOs) play a fundamental role in the adaptation to different habitats and environmental conditions. To verify the influence of these factors on the EO of Artemisia absinthium L., we conducted a pharmacognostic study on this species, collected during both the vegetative (V) and flowering (F) stages, in two different ...
