Recognition of flowers by pollinators

Current Opinion in Plant Biology, 2006
The flowers of angiosperm plants present us with a staggering diversity of signal designs, but how did this diversity evolve? Answering this question requires us to understand how pollinators analyze these signals with their visual and olfactory sense organs, and how the sensory systems work together with post-receptor neural wiring to produce a ...

deepTFBS: Improving within‐ and Cross‐Species Prediction of Transcription Factor Binding Using Deep Multi‐Task and Transfer Learning

Advanced Science, EarlyView.
DeepTFBS leverages deep learning to predict transcription factor binding sites across species, integrating multi‐task and transfer learning approaches to improve performance in data‐scarce scenarios. This study demonstrates enhanced accuracy in intra‐ and cross‐species prediction, revealing conserved regulatory patterns and functional variants.

Integrating pollinators’ movements into pollination models

Frontiers in Ecology and Evolution
Accurate prediction of pollination processes is a key challenge for sustainable food production and the conservation of natural ecosystems. For many plants, pollen dispersal is mediated by the foraging movements of nectarivore animals. While most current models of pollination ecology assume random pollen movements, studies in animal behaviour show how ...

Phytophthora Disrupts Plant Immunity by Manipulating Nitric Oxide Homeostasis Through GSNOR Inhibition

Advanced Science, EarlyView.
Phytophthora capsici effector PcRD18 targets tomato GSNOR to disrupt NO homeostasis, promoting S‐nitrosylation of immune proteins like RBOHD. This suppresses ROS bursts and promotes pathogen infection. Mutation of the PcRD18‐binding sites of GSNOR avoids pathogen manipulation and offers a strategy to enhance crop resistance. Abstract Nitric oxide (NO),

Bioinspired Claw‐Engaged Adhesive Microparticles Armed with γGC Alleviate Ulcerative Colitis via Targeted Suppression of Macrophage Ferroptosis

Advanced Science, EarlyView.
γGC deficiency in ulcerative colitis drives macrophage ferroptosis‐mediated inflammation. Claw‐engaged microparticles armed with γGC (γGC‐MPs) enhance lesion targeting, promoting localized γGC release and tissue uptake. On the cover, Monkey King (Macrophages) was bound by the Immortal‐Binding Rope and subsequently sealed beneath the Five‐Fingered ...

Antagonistic Ghd7‐OsNAC42 Complexes Modulate Carbon and Nitrogen Metabolism to Achieves Superior Quality and High Yield in Rice

Advanced Science, EarlyView.
The complex centered on Ghd7 binds to numerous carbon and nitrogen metabolism genes on the genome through the corresponding motifs and transactivates the transcriptional expression of these carbon and nitrogen metabolism genes. With the assistance of OsNAC42 and other unknown Ghd7‐interacting proteins, this complex can regulate different metabolic ...

Foraging Behavior of Honeybees (Apis Mellifera L.) and Ground Bumblebees (Bombus Terrestris L.) and its Influence on Seed Yield and Oil Quality of Oil Tree Peony Cultivar ‘Fengdan’ (Paeonia Ostii T. Hong et J. X. Zhang)

Journal of Apicultural Science, 2020
Oil peony (Paeonia spp.) is a new type of woody oil crop in China with a large cultivation area. Inadequate pollination is one of the main reasons for low seed yield.

Peptide Hormone‐Mediated Regulation of Plant Development and Environmental Adaptability

Advanced Science, EarlyView.
In this review, recent advances in understanding the roles of plant peptide hormones in regulating growth, reproduction, and environmental adaptability are systematically summarized. It further elucidates the challenges in studying these peptides, such as their low abundance, functional redundancy, and complex signaling mechanisms, and highlights their

Pollination deficit in open-field tomato crops (Solanum lycopersicum L., Solanaceae) in Rio de Janeiro state, Southeast Brazil

Journal of Pollination Ecology, 2013
More than 70% of world’s crops benefit from biotic pollination, and bees are their main pollinators. Despite the fact that some of these insects have been broadly studied, understanding the interactions between plant crops and their pollinators with a ...
