Treatment of ‘Pikantni’ feed bean plants at the 10 cm shoot stage with the broad-spectrum growth stimulant Biolane and the semi-synthetic film-forming plant growth regulator N¹-Acetyl-5-Methoxykynuramine (AMK) with antioxidant activity induced significant morphogenetic changes. The agents substantially accelerated the growth of the above-ground biomass, particularly from the branching stage onwar…

Most woody plants grow flowers from new growth or shoots, but some species perform cauliflory – flowering from their main stems and mature branches. More commonly seen in tropical forests, cauliflory is rare in temperate species. Eastern Redbud (Cercis canadensis) is one of those rare examples. With beautiful pink flowers, this deciduous tree or shrub is native to North America. Its range include…

Abstract Background Arbuscular mycorrhizal fungi (AMF) form symbioses with crops, enhancing nutrient uptake and stress tolerance. However, their responses to agronomic practices such as cover cropping and microbial grain inoculation remain poorly understood under field conditions. For maize, one of the world’s most important crops, it is still unclear how these management strategies influence AMF…

Abstract Background Uranium (U) contamination poses a serious threat to ecosystems. Phytoremediation offers an eco-friendly solution but is often limited by metal toxicity in plants. Arbuscular mycorrhizal fungi (AMF) can enhance plant tolerance and improve phytoremediation efficiency, while their specific interaction with polyamine (PA) metabolism under U stress remains unclear. This study inves…

This study aims to develop and evaluate a deep learning-based mobile application for the automated classification of ornamental plants, addressing challenges associated with visual similarity among species and environmental variability during image acquisition. The proposed system utilizes a Convolutional Neural Network (CNN) based on the MobileNetV2 architecture, selected for its lightweight str…

Abstract Plants have developed adaptive strategies to combat dehydration, including forming associations with microbes, which help plants cope with drought by altering hormone levels, enhancing antioxidants, or improving water uptake. Selaginella species, the resurrection plants, can endure desiccation and revive with rehydration. Here, we investigated the bacteriome of leaves and roots of S. con…

Abstract The Grapevine fanleaf virus (GFLV) transmitted by the vector nematode Xiphinema index causes severe losses in viticulture. Truly resistant rootstocks that inhibit nematode development and virus transmission to grapevines are not available. Seedlings with genetic background of the accession Vitis shuttleworthii D’Arpa were evaluated using an established screening system to test for nemato…

Abstract The objective of this work was to test a new method for Al and Pb histolocalization using Chrome Azurol S (CAS) and Pyrogallol Red (PGR), respectively, using roots from Typha domingensis Pers. plants grown in iron mining tailings. For both CAS and PGR, we tested two solvents (distilled water pH 6.7 and 100 mM phosphate buffer pH 5.0), two concentrations (0.1% and 0.5%, m V − 1 ), and thr…
