Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.

Adaptations that Reduce Water Loss01:57

Adaptations that Reduce Water Loss

25.0K
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

Responses to Salt Stress

Salt stress—which can be triggered by high salt concentrations in a plant’s environment—can significantly affect plant growth and crop production by influencing photosynthesis and the absorption of water and nutrients.

The Calvin Benson Cycle01:46

The Calvin Benson Cycle

4.4K
Ribulose 1,5- bisphosphate carboxylase/oxygenase (RuBisCo) is a critical enzyme that catalyzes carbon dioxide assimilation during photosynthesis. However, it is an inefficient enzyme, having an extremely slow catalytic rate. A typical enzyme can process about a thousand molecules per second; however, RuBisCo fixes only around three-carbon dioxides per second. Photosynthetic cells compensate for this slow rate by synthesizing very high amounts of RuBisCo, making it the most abundant single...

Key Elements for Plant Nutrition02:35

Key Elements for Plant Nutrition

18.6K
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

C4 Pathway and CAM01:27

C4 Pathway and CAM

45.1K
Most plants use the C3 pathway for carbon fixation. However, some plants, such as sugar cane, corn, and cacti that grow in hot conditions, use alternative pathways to fix carbon and conserve energy loss due to photorespiration. Photorespiration is the process that occurs when the oxygen concentration is high. Under such conditions, the rubisco enzyme in the Calvin cycle binds O2 instead of CO2, which halts photosynthesis and consumes energy.

The C4 pathway is used by plants such as...

Summary
This summary is machine-generated.

A microbial biostimulant combined with calcium significantly enhanced winter oilseed rape

Area of Science:

  • Agricultural Science
  • Plant Physiology
  • Biotechnology

Background:

  • Drought stress poses a significant threat to winter oilseed rape (Brassica napus L.) production.
  • Understanding plant responses and developing mitigation strategies is crucial for crop resilience.

Purpose of the Study:

  • To investigate the impact of simulated drought on Brassica napus.
  • To evaluate the efficacy of a microbial biostimulant (ProbioHumus) and calcium (Ca) in mitigating drought stress.
  • To elucidate the underlying biochemical mechanisms of drought tolerance.

Main Methods:

  • Winter oilseed rape cv. 'Visby' was subjected to simulated drought under controlled conditions.
  • Treatments included ProbioHumus application and soil calcium addition, individually and in combination.

  • Physiological and biochemical parameters were assessed during drought and recovery phases.

    • Main Results:

    • ProbioHumus + Ca significantly reduced wilting, increasing leaf relative water content (RWC) by 87%.
    • This combination markedly enhanced drought tolerance, evidenced by a 4-fold increase in proline content and improved photosynthetic pigment levels (10-28%).
    • ProbioHumus + Ca also reduced oxidative stress markers (H2O2 by 53%, MDA by 45%) and promoted stomatal opening.

    Conclusions:

    • The combined application of ProbioHumus and calcium is the most effective strategy for improving winter oilseed rape survival and recovery post-drought.
    • These ecological approaches show promise for enhancing crop resilience under field conditions.
    • The study identifies key biochemical pathways involved in plant drought tolerance.
