Messenger

When ProAct is sprayed onto the plant it binds to the natural harpin receptors. These early warning receptors react as if ProAct was a pathogen attacking the plant. This stimulants the plant to react in its defence and to speed up growth.

Description

How does mighty messenger work?

Mighty Messenger, or Messenger for short, is a new Harpin alpha beta (αβ) protein formulation. It’s a second-generation protein that works just like the protein that bacterial plant pathogens release.

1. RECEPTION
When Messenger is sprayed onto the plant, it binds to the natural harpin receptors. These early-warning receptors react as if Messenger is a bacterial pathogen attacking the plant.

2. TRANSDUCTION
Within minutes, this stimulates the plant to activate its defence systems. Messenger amplifies the natural growth processes, resulting in increased nutrient uptake, photosynthesis, vigour and reproductive responses. The stress-defence response increases plant tolerance to stress caused by the environment, physiological shifts in plant growth and biological agents such as disease pathogens. Environmental stresses are drought, heat, hail, frost and flooding.

3. RESPONSE
These reactions activate both innate growth and stress-defence pathways within the plant, resulting in healthier, stronger crops that are characterised by better tolerance to stress conditions, better growth and increased production.

 

The effects of using mighty messenger

Calcium levels outside the plant cell are typically 1000 times higher than inside the cell. Messenger can induce a calcium flux within minutes after application, allowing higher levels of calcium to flow
into the cell.

NORMALLY A PLANT ONLY INDUCES THIS RESPONSE WHEN UNDER ATTACK. MESSENGER IS UNIQUE IN ITS ABILITY TO ACTIVATE CALCIUM MOVEMENT.

The calcium content of the plant cell is separated into ‘free’ and ‘bound’ calcium. The concentration of cytosolic free calcium is maintained at low levels because of the signalling nature of calcium. Calcium is a macro-element nutrient; it can also be referred to as a plant hormone. Calcium works similarly to adrenaline in humans- it is held in low concentrations and only elevated when under attack.

 

Three main types of calcium in plant cells

A plant under attack increases the calcium levels in its cells by opening its calcium channels and using the calcium as a signalling compound
to trigger a response throughout the plant cells. For farmers who want to increase calcium loads in fruit, Messenger is a great product
when used in combination with calcium.

Messenger opens the calcium channels and rapidly increases the uptake and translocation.
