Sentences with phrase «plants against pathogens»

«Through our research we discovered that defense against extracellular pathogens (ETD) involves different plant genes from those involved in the defense against intracellular pathogens.

Dr Stotz continued: «This concept of plant ETI does not really explain the second line of defense in the interaction of plant hosts protecting themselves against extracellular fungal pathogens — i.e. those foliar fungal pathogens that get into the leaf of the plant to exploit the space between its cells, known as the apoplast, to retrieve nutrients from the plant.

Our research enhances the traditional understanding of the plant defense system and describes a new concept describing how plants protect themselves against the pathogens that grow in the space outside plant cells (the apoplast)-- a new concept called effector - triggered defense or ETD.»

A new understanding as to how plants defend themselves against some pathogens that cause crop diseases is proposed by researchers from the University of Hertfordshire to help scientists breed new, more successful disease - resistant agricultural crops.

By exploiting new molecular and genetic insights, the research, done in collaboration with Pierre de Wit from Wageningen Agricultural University in the Netherlands, provides a better understanding of the defense system of crop plants against the damaging pathogens that grow in the spaces between plant cells.

The concept of ETI was developed to describe defense against pathogens that enter into plant cells (e.g. wheat rusts and mildews, potato late blight pathogens) and fits their defense mechanisms well.

The paper «Effector - triggered defense against apoplastic fungal pathogens» is published online at Trends in Plant Science.

Plant defenses against pathogens follow a salicylic acid mediated pathway.

Xinnian Dong of Duke University in North Carolina and colleagues studied how Arabidopsis thaliana, a small flowering plant, defends itself against a fungus - like pathogen, Hyaloperonospora arabidopsidis.

Plant immune systems, like those of humans and animals, face a difficult balancing act: they must mount responses against ever - evolving pathogens, but they must not overdo it.

These plants also showed strong immune responses in the form of an increased concentration of salicylic acid, a plant hormone which regulates defense against pathogens.

Innate immunity is the first line of defense against pathogens in all plants and animals.

«While it seems like it would be good that the plant grows faster, other functions that the fungal or animal partners provide — such as protection against pathogens or drought and assistance in gathering micronutrients like iron — could be compromised.

The reason could be that plant defenses against pathogens gradually weaken after a fire, Moritz and Odion speculate — for instance, from stiffer competition among plants as they grow, decreased chemical defenses as they age, or depletion of soil nutrients.The findings suggest that California's fight against forest fires over many decades may have precipitated or accelerated the outbreak, and that perhaps controlled burning could be used to halt it, the authors say.

These proteins are involved in plant stress responses in general, particularly in defense against pathogen attack.

RNAi is effective against viruses and fungal pathogens and can also protect plants against insect pests, reducing the need for chemical pesticides.

They initiate different processes at certain times of the day: from the opening of the flowers and the defence against pathogens in plants to the sleep - wake rhythm in humans.

This waterproof film, a very ancient adaptation to terrestrial life, prevents excessive water loss and protects plants against insects and various pathogens.

The scientists could demonstrate the potential of the protein arrays in the context of plant hormone signaling pathways, which, for example, mediate responses to drought stress or against pathogens.

A team of international researchers has uncovered a mechanism by which plants are able to better defend themselves against disease - causing pathogens.

Toll / interleukin -1 receptor (TIR) domain - containing proteins play important roles in defense against pathogens in both animals and plants, connecting the immunity signaling pathways via a chain of specific protein - protein interactions.

We have used three variations of a strategy known as pathogen - derived resistance (PDR), whereby fragments of DNA from the pathogen are inserted into the plant genome providing it with resistance against the pathogen.

P. fluorescens strains also exhibit different mechanisms, either direct or indirect, that promote plant growth and / or biological control against fungi and other pathogens (5).

Tom gained his PhD from SLU in Uppsala under Christina Dixelius working with plant defence against pathogens.

Among research that has faced industry disapproval, says Benbrook, are studies on evolving weed resistance, on plant pathogens, and on susceptibility of non-pest insects to the Bacillus thuringiensis (Bt)- derived toxins that protect the GM plants against insect pests.

While some of these organisms are harmful to roots by causing damage or even plant death, others are beneficial and enhance nutrient acquisition and protect roots against pathogens.

As a first line of defense against bacterial pathogens, plant cells recognize and respond to tiny bacterial molecules, such as pieces of flagellin that slough off the whip - like flagella that help the bacteria move.

Regardless many of the defensive mechanisms that plants have against insects and pathogens require that the plant recognize that it is being attacked.
