Plant defense against herbivory or host-plant resistance (HPR) describes a range of adaptations evolved by plants which improve their survival and reproduction by reducing the impact of herbivores. Plants can sense being touched, and they can use several strategies to defend against damage caused by herbivores. Many plants produce secondary metabolites, known as allelochemicals, that influence ...

Some plants use thorns to protect themselves from being eaten by larger animals. Thorns can poke and bother an animal enough to get it to move on to another plant. Some examples of thorns include the thorns on the stem of a rose bush and the spines on a cactus. Certain types of cactus spines can be especially dangerous as they have barbs that ...

· Oxalotrophic Stenotrophomonas isolated from tomato rhizosphere are able to protect plants against oxalate-producing pathogens by a combination of actions including induction of plant defence signalling callose deposition and the strengthening of plant cell walls and probably the degradation of oxalic acid. Oxalic acid plays a pivotal role in the virulence of the necrotrophic fungi …
· Plants defense mechanism. Plants diseases or phytopathogens affects plants right from the planting stage up to the harvesting and storage of the produce. Consequently, the plants have evolved several different mechanisms by which they defend themselves. These defense mechanisms in plants are termed as "BASAL RESISTANCE".
One of the most efficient mechanisms protecting plants and other photosynthesizing organisms under overexcitation conditions is the xanthophyll cycle. At the molecular level some carotenoids of this cycle act as quenchers of 1Chl*, thus preventing the formation of ROS (Fig. 2(B)).16,17 Six types of xanthophyll cycle have been described.
· Plants'' major defense mechanisms to adjust to heavy metal stress and to protect plant cells from oxidative stress are scavenging free radicals by ROS. ROS stimulates enzyme activities, either antioxidant enzymes or nonenzyme activities [77–80].
compounds, defend plants against a variety of herbivores and pathogenic microorganisms as well as various kinds of abiotic stresses. This review presents an overview about some of the mechanisms by which plants protect themselves against herbivory, pathogenic microbes and various abiotic stresses as well as specific plant
· Study on mechanisms that protect plant fertility from heat stress Plant fertility is dramatically affected by spikes in temperature, directly resulting in yield reduction and economic loss. Understanding the molecular mechanisms that underpin plant fertility under environmental constraints is critical to safeguarding food production.

· Mimosa pudica, also known as the sensitive plant, is a creeping herb of the pea family, Fabaceae, that is often grown out of curiosity — the compound leaves fold inward and droop when they are touched or shaken, a way of defending themselves from harm.This makes them appear dead and thus unappetizing. They re-open a few minutes later. The types of movement the plant undergoes are …
· 1. Water plants thoroughly in cold weather. Water traps heat in the soil. Watering your plants keeps the soil warm and helps them withstand the cold. Keep your plant on its watering schedule to protect it from cold weather. Water plants …
Plant defense. Plants can''t run away from danger like most animals can, so they have developed their own weapons and armor in order to protect themselves. A plant''s main predators are the animals that feed on them. These range from tiny insects that chew their way through leaves to large mammals that eat whole plants.
· Anthocyanins protect plants against various biotic and abiotic stresses (Chalker-Scott, 1999; Ahmed et al., 2014), partially due to their powerful antioxidant properties. In addition, anthocyanin-rich food products have become increasingly popular due to their attractive colors and suggested benefits for human health ( Pojer et al., 2013 ).

· Thousands of plants—including common foods like apples, spinach, and lima beans—are poisonous to other species besides humans.. That''s because these plants produce hydrogen cyanide compounds, which attach to either sugar or fat molecules via a process called cyanogenesis. They remain stored in the plant until they are needed, i.e. when insects try to eat them.
