Perspectives on deciphering mechanisms underlying plant heat stress response and thermotolerance [PDF]

, 2013
Global warming is a major threat for agriculture and food safety and in many cases the negative effects are already apparent. The current challenge of basic and applied plant science is to decipher the molecular mechanisms of heat stress response (HSR ...

Higher Temperature at Lower Elevation Sites Fails to Promote Acclimation or Adaptation to Heat Stress During Pollen Germination

Frontiers in Plant Science, 2018
High temperatures associated with climate change are expected to be detrimental for aspects of plant reproduction, such as pollen viability. We hypothesized that (1) higher peak temperatures predicted with climate change would have a minimal effect on ...

Germinability and pollen viability of four improved cultivars of palm oil under laboratory conditions [PDF]

, 2018
The success of assisted pollination in oil palm is essential for oil production, since it determines the amount of well-formed fruits; in this process, the pollen quality, expressed as viability and germinability, is of great importance.

Pollen physiology and fertilisation in Vicia Faba L [PDF]

, 1990
In many legume crop species, early-formed fruits or those located closest to the photosynthate are more likely to mature than other fruits. This is so in the Vicia faba crop.

Metabolomic and transcriptomic analyses reveal that sucrose synthase regulates maize pollen viability under heat and drought stress

Ecotoxicology and Environmental Safety, 2022
Maize pollen is highly sensitive to heat and drought, but few studies have investigated the combined effects of heat and drought on pollen viability. In this study, pollen's structural and physiological characteristics were determined after heat, drought,

Observations and modelling of birch pollen emission and dispersion from an isolated source [PDF]

, 2014
The occurrence of allergic diseases in western countries increased during the last decades due to greater awareness towards a hygienic lifestyle. The hygiene hypothesis relates the reduced expo- sure to microbial pollution to an underdevelopment of the

Autonomous Navigation of Pollen‐Inspired Magnetic Microrobots for Biomedical Applications

Advanced Robotics Research, EarlyView.
A sunflower pollen‐inspired magnetic microrobot enables controlled rolling navigation in vessel‐like environments. Its open geometry reduces hydrodynamic drag, while vision‐based closed‐loop control, shortest‐path planning, and reinforcement learning support target‐reaching and maze navigation with microrobot‐scale accuracy, highlighting a route toward
