Honey bees preferentially consume freshly-stored pollen. [PDF]

PLoS ONE, 2017
Honey bees (Apis mellifera) collect and store both honey and pollen in preserved forms. Pollen storage involves the addition of honey or nectar and oral secretions to pollen granules.

The Mitochondrial Protein RESISTANCE to APHIDS 9 Interacts with S40 to Resist Aphid Infestation by Modulating Reactive Oxygen Species Homeostasis in Maize (Zea mays)

Advanced Science, EarlyView.
This study identifies the mitochondrial protein RTA9, a member of the Domain of Unknown Function 641 family, together with its partner S40, as key regulators of aphid resistance in maize. RTA9 promotes S40 degradation and modulates reactive oxygen species accumulation.

Diltiazem Reduces Mortality and Breakdown of ATP in Red Blood Cell Induced by Isoproterenol in a Freely Moving Rat Model in Vivo

Metabolites, 2014
The benefit of calcium channel blockers for cardiovascular prevention against heart attack and stroke has not been firmly supported. We investigated the possible cardiovascular protective effect of diltiazem (DTZ) against injury induced by isoproterenol ...

Honey bee foraging distance depends on month and forage type [PDF]

, 2015
To investigate the distances at which honey bee foragers collect nectar and pollen, we analysed 5,484 decoded waggle dances made to natural forage sites to determine monthly foraging distance for each forage type.

An Automated Lab‐On‐A‐Chip Approach for Pollen Tube Growth Manipulation in a Controlled Chemical Environment

Advanced Science, EarlyView.
Here, a microfluidic‐based robotic lab‐on‐a‐chip (LoC) device is presented for automated, continuous‐flow investigation and manipulation of single pollen tube growth under precisely controlled chemical gradients. This closed‐loop system streamlines data collection and analysis while enhancing experimental precision compared to manual methods ...

The CtrCBL1/CtrCIPK6 Complex of Citrus Phosphorylates CtrBBX32 to Regulate CtrSTP1‐Mediated Sugar Accumulation and Cold Tolerance

Advanced Science, EarlyView.
The CtrCBL1‐CtrCIPK6 module of trifoliate orange (Citrus trifoliata L.) phosphorylates CtrBBX32, triggering its protein degradation under cold conditions, thereby relieving CtrBBX32‐mediated transcriptional repression of CtrZAT10 and CtrSTP1. The consequent upregulation of CtrZAT10 further activates CtrSTP1 expression, which enhances hexose transport ...

The transcription factors and pathways underpinning male reproductive development in Arabidopsis

Frontiers in Plant Science
As Arabidopsis flowers mature, specialized cells within the anthers undergo meiosis, leading to the production of haploid microspores that differentiate into mature pollen grains, each containing two sperm cells for double fertilization.
