Proline – A Deeper Look at How Yield Plus Protects & Enhances Plants


Research has discovered that all plants which survive in stressful conditions (especially desert plants) are rich in an amino acid called proline. In fact, all plants automatically produce proline as a response to stress.

This includes internal stress situations like, during reproduction, flowering and fruit set. But it also includes external environmental conditions like heavy rain/flooding… lack of moisture and drought… frost… heat waves…hail… high winds… pest attacks and disease… poor soil and high salinity… and more.

Regardless of the situation, these high levels of proline enhance a plant’s normal functions in extreme conditions… comparable to the effect that Adrenalin has on human beings in stressful situations.

A Plant’s Natural Defenses & the Consequences of Stress

The problem is that plants don’t have an unlimited supply of proline. Depending on how extreme the stress, they won’t always have enough to protect themselves for the entire duration of the stress.

This is often the case, and in response plants raise their primitive defense mechanisms…  as seen by the shedding flowers, fruit and leaves or the slowing their metabolic processes to conserve energy. This has a big effect on the overall quality of the plant and is likely to cause reduced growth, reduced fruit size and yield.

And the question is this… how quickly… and for how long will they raise their defenses? Or will they even raise them at all?

L-cysteine – The Active Ingredient of Yield Plus

Yield Plus is based on L-cysteine, a naturally occurring amino acid found in plants. Yield Plus is applied at very low concentrations and is absorbed quickly by the plant.

As a result of L-cysteine, the proline level increases through the process known as proline synthesis. The increased proline enables plants to tolerate certain kinds of stress for much longer than they would normally be able to.

A Powerful Antioxidant

L-cysteine works as an antioxidant on proline. With oxidation in general, exposure to oxygen causes a reduction to an organic substance.

By introducing the amino acid L-cysteine to the plant, the oxidation of proline is blocked. This prevents proline from oxidizing… and allows proline synthesis to take place… where plant automatically generates more proline.

Enhanced Metabolism & Osmotic Functions

Enhanced osmotic functions are a characteristic of increased proline levels. This refers to better water flow at the cellular level to improve the plant’s overall metabolism.

This directly reduces osmotic stress… or sudden, dangerous changes in the water levels of the plant’s cells… like we see in drought conditions, lack of moisture and high salt content in the soil.

Raising Sugar Levels to Boost Vitality & Recovery

Not only does proline assist the plant with external and internal stress factors, but it also helps it recuperate quicker after a stress situation.

After the stress passes, the excess proline converts into another amino acid, called glutamate. This leads to raised levels of plant sugars… making the plant more vigorous and enhancing overall metabolism and other things like:

  • Nutrient absorption
  • Protein synthesis
  • Carbon cell development
  • And leads to a better taste.

This also holds true in normal conditions as proline proves to be a great benefit to plants even in the absence of stress.

A Natural Stress Control Tool

The increased proline produced by the plant when Yield Plus (L-cysteine) is applied gives the plant an even more powerful, and natural way to control stress.

The result is almost always a better quality plant that grows far greater than normal. In particular with fruits, vegetables and grains, this means a larger and often earlier harvest, with a higher sugar content and improved freshness or shelf-life.

Not a miracle cure

Yield Plus is not a fertilizer, stimulant or “wonder product,” nor is it a replacement for good agricultural practices, including disease control. In reality, it is an organic protein substance which is mixed with water and sprayed on plants to control stress.

Without Yield Plus, situations like a sudden cold spell, or heat wave, will cause a reaction where plants start to shut down and conserve their energy levels so that, once the stress is over, the plant will be prepared to resume its normal growth.

And without the ability to produce enough proline, there’s no guarantee they’ll even resume their or growth or survive the stress.

Good Care & Proper Nutrients Required

In general, plants need to build their own proteins based to support growth and development, including during periods of stress where they have even greater needs.

A plant’s normal proline levels are also dependent on adequate water, light and micro and macro nutrients. The growing conditions and the level of care provided are crucial as well. And there no exception to this, even when using Yield Plus.

And of course, the faster and enhanced growth with Yield Plus is not guaranteed… this depends greatly on good agronomic practices and providing enough nutrients to support this additional growth potential that Yield Plus makes possible.

However, plants treated correctly with Yield Plus will be able to withstand stressful conditions and continue with their normal metabolic functions as if the stress factor wasn’t there.

Therefore, it helps any plant grow to its true genetic potential, far better than it would be able to on its own.
