Cross‐Scale Hierarchical Targeted Delivery System Based on Small‐Scale Magnetic Robots

Advanced Robotics Research, EarlyView.
This article reviews a cross‐scale hierarchical targeted delivery system that integrates magnetic continuum robots and magnetic microrobots. By combining rapid long‐range navigation with precise microscale targeting, the system overcomes key limitations of single‐scale approaches.

Arabidopsis COG Complex Subunits COG3 and COG8 Modulate Golgi Morphology, Vesicle Trafficking Homeostasis and Are Essential for Pollen Tube Growth. [PDF]

PLoS Genetics, 2016
Spatially and temporally regulated membrane trafficking events incorporate membrane and cell wall materials into the pollen tube apex and are believed to underlie the rapid pollen tube growth.

Gibberellin Regulates Pollen Viability and Pollen Tube Growth in Rice [PDF]

The Plant Cell, 2007
AbstractGibberellins (GAs) play many biological roles in higher plants. We collected and performed genetic analysis on rice (Oryza sativa) GA-related mutants, including GA-deficient and GA-insensitive mutants. Genetic analysis of the mutants revealed that rice GA-deficient mutations are not transmitted as Mendelian traits to the next generation ...

A Pollen‐Enhanced Bionic Mechanoreceptor Induced by Asymmetric Ionic Convection in Hydrogel for Sensory‐Augmented Prostheses

Advanced Science, EarlyView.
This work proposed a pollen‐enhanced bionic mechanoreceptor based on ionic convection. Leveraging the ion anchoring effect of the pollen particle, the output performance could be ∼12 times higher than the original state. By employing deep learning models as AI brains, the feasibility of a sensory‐augmented prosthesis consisting of a pollen‐enhanced ...

Roles for NO and ROS signalling in pollen germination and pollen-tube elongation in Cupressus arizonica

Biologia Plantarum, 2015
Roles for nitric oxide (NO) and reactive oxygen species (ROS) during pollen-tube growth have been well established in angiosperms, but there remains lack of information regarding their potential signalling roles in pollen tubes in gymnosperms.

Adaptive Responses of Tropical Crops: A Multi‐Scale Omics Integrated Perspective

Advanced Science, EarlyView.
Tropical crops integrate genomic, morphological, physiological, and ecological adaptations to thrive under extreme and variable environments. This review highlights how natural selection, domestication, and breeding shape stress resilience, resource‐use strategies, and productivity in sugarcane, banana, cassava, rubber and oil palm, offering new routes

Pollen tube incompatibility reaction on the stigma in selfpollinated Sinapis alba L.

Acta Societatis Botanicorum Poloniae, 2014
After selfpollination of Sinapis alba L. pollen tubes growth is inhibited on the stigma. The pollen grains germinate 3-4 hours after pollination. The pollen give rise to one or more pollen tubes. They grow along the papillae.

Combining phenotypic, physiological, and multi‐omics studies to provide new insights on the role of 2,4‐epibrassinolide in regulation of seed shattering in Elymus sibiricus L.

Grassland Research, EarlyView.
Abstract Background Seed shattering limits the production of Elymus sibiricus L., and application of exogenous brassinosteroid significantly alleviates plant organ abscission. Methods To explore the potential regulatory network of brassinosteroid on seed shattering, the abscission zone of E. sibiricus cv. Lanyu No.

Boron toxicity causes multiple effects on Malus domestica pollen tube growth

Frontiers in Plant Science, 2016
Boron is an essential micronutrient for plants. However, boron is also toxic to cells at high concentrations, although the mechanism of this stress is not known.
