Multi-omics analysis reveals activation of jasmonate synthesis and modulation of oxidative stress responses in boron deficient pea shoots (OA)
New study in pea shoots shows boron deficiency dynamically alters metabolism - increasing oxidative stress while reprogramming biosynthesis of lignins, flavonoids and jasmonates. Jasmonate accumulation notably plays role in modulating membrane/cell wall function during deficiency.
Improving the mapping of coastal invasive species using UAV imagery and deep learning ($)
https://www.tandfonline.com/doi/full/10.1080/01431161.2023.2251186
Invasive species of saltmarsh in Ireland is threatening local flora and fauna. New study shows that using Unoccupied Aerial Vehicles (UAVs) and deep learning to map the spread offers a cost-effective solution for site-specific management strategies. The study hints at the potential of tech to combat environmental issues ๐ฟ
How can residents protect and promote pollinators? The diffusion of residential pollinator-friendly gardening ($)
https://www.sciencedirect.com/science/article/abs/pii/S0301479723016651
Researchers explore residential green spaces as potential havens for pollinators impacted by urbanization and land use changes. Despite willingness to adopt more pollinator-friendly gardening practices, uptake remains low. Addressing complexity and raising visibility could boost these important practices. ๐
Leaf micromorphology affects the particulate matter retention in herbaceous plants: An in situ interspecies comparison ($)
https://onlinelibrary.wiley.com/doi/abs/10.1002/clen.202200289
This study reports that the ability of herbaceous plants to retain atmospheric pollutants can vary between species and depends on leaf characteristics. The plant Liriope spicata, for instance, showed the greatest capacity to hold particulate matter, due to qualities like larger stomata and more surface grooves. ๐ฟ
Assessing the use of natural colonization to create new forests within temperate agriculturally dominated landscapes (OA)
https://onlinelibrary.wiley.com/doi/10.1111/rec.14004
Scientists have explored the effectiveness of naturally spreading forests in agricultural landscapes to fight climate change and protect biodiversity. While this approach has potential, their study shows it's a slow and variable process, suggesting it needs to be paired with tree planting efforts for optimal impact. ๐ณ
Rodents may be important pollinators of banksias in subtropical Australia ($)
https://www.publish.csiro.au/AM/AM23019
Non-flying mammals might play a significant role in the pollination of Australian plants. Recent findings suggest that grassland melomys may contribute to the pollination of Banksia ericifolia due to their high nocturnal pollen loads ๐ญ
Knowledge of the role of non-flying mammals in the pollination of the Australian flora is still incomplete. We captured non-flying mammals visiting Banksia ericifolia in north-east New South Wales and sampled pollen from their heads. The grassland melomys (Melomys burtoni) was captured >4 times more often than the house mouse (Mus musculus) or the swamp rat (Rattus lutreolus). Nocturnal pollen loads (mean 295โยฑโ53 grains) measured on the melomys are among the highest for an Australian non-flying mammal. Pollen removal from flowers at night was widespread. These observations suggest the grassland melomys is likely to play an important role in the pollination of subtropical B. ericifolia.
Divergent response of leaf unfolding to climate warming in subtropical and temperate zones ($)
https://www.sciencedirect.com/science/article/abs/pii/S016819232300432X
Leaf unfolding in subtropical forests happens 20 days earlier than temperate ones due to climate warming. Moreover, warming impacts subtropical leaf unfolding more noticeably, posing a threat to these ecosystems under continued warming. ๐ฟ
Different Urbanization Levels Lead to Divergent Responses of Spring Phenology ($)
https://www.ingentaconnect.com/contentone/asprs/pers/2023/00000089/00000010/art00009
Urban vegetation impacts the carbon cycle and reacts differently to distinct levels of urbanization. The spring onset of plant growth (SOS) in urban areas widely occurs earlier than in rural areas. Threshold levels of urbanization intensity show varying responses with implications for future climate & environmental changes.๐
Spatiotemporal distribution of reactive oxygen species production, delivery, and use in Arabidopsis root hairs (OA)
https://academic.oup.com/plphys/advance-article/doi/10.1093/plphys/kiad484/7259853
Scientists used fluorescence imaging to observe plant responses to stress. They found selective probes can detect reactive oxygen species (ROS) in living cells, leading to a better understanding of how plants manage ROS during root hair formation.๐ฑ
Sporocarp nutrition of ectomycorrhizal fungi indicates an important role for endemic species in a high productivity temperate rainforest ($)
https://nph.onlinelibrary.wiley.com/doi/abs/10.1111/nph.19280
Study finds endemic fungi species, confined to specific regions, exhibit superior adaptive traits contributing to rainforest nutrition and productivity. Differences in their sporocarp nutrition noted; endemic species had increased concentration of N, potassium, and magnesium.๐
