“…18,19 In this sense, NLRs could be conceived as guard proteins similar to plant NB-LRRs. 20 21 and the counter-intuitive term 'hypersensitiveness' was coined in 1915, 22 to describe a pathogen-triggered cell death reaction that correlated with disease resistance in wheat infected with Puccinia graminis. Morphologically, HR is a specific and unique type of cell death.…”

Cell death has a central role in innate immune responses in both plants and animals. Besides sharing striking convergences and similarities in the overall evolutionary organization of their innate immune systems, both plants and animals can respond to infection and pathogen recognition with programmed cell death. The fact that plant and animal pathogens have evolved strategies to subvert specific cell death modalities emphasizes the essential role of cell death during immune responses. The hypersensitive response (HR) cell death in plants displays morphological features, molecular architectures and mechanisms reminiscent of different inflammatory cell death types in animals (pyroptosis and necroptosis). In this review, we describe the molecular pathways leading to cell death during innate immune responses. Additionally, we present recently discovered caspase and caspase-like networks regulating cell death that have revealed fascinating analogies between cell death control across both kingdoms.

“…Hypersensitive responses were first described in the context of plant defence against microbial disease (Ward, 1902;Stakman, 1915;Klement and Goodman, 1967). A hypersensitive response is made visible by a rapid, locally restricted necrosis of cells at the infection site.…”

Plant responses towards insect egg depositions range from changes in plant tissue to alterations of the plant's volatile bouquet. Such responses may result either in defence against herbivores or even in their protection. Defensive tissue changes in plants caused by egg depositions are known as formation of neoplasms and as hypersensitive response. Tissue changes that positively affect herbivores are induced by egg depositions of several gall forming insects. These manipulate plants to produce nutritive and protective tissues for the progeny.Indirect plant defence responses towards egg deposition do not affect the eggs or hatching larvae directly, but employ the third trophic level. Changes in the plants' volatile emission induced by insect egg deposition are known to attract egg

“…conditions were right the fungus suppos edly grew out of certain cells containing this "mycoplasm" and spread throughout the leaf in that area. Ward (1882) had already shown that the coffee rust fungus, Hemileia vastatrix Berk & Br., infected coffee by entrance of germ tubes through stoma ta. He showed that these germ tubes originated from germinated urediospores on the surface of the leaf.…”

“…Apparently the fungus is able to obtain nourishment from the host in some way other than through haustoria. Ward (1905) hypothesized that the mycelium in a resistant variety dies from starvation. However, the fact that the fungus can obtain nutrients and grow in resistant tissues without forming successful haustoria, suggests that death of the mycelium may be due to some toxic substance.…”

On the Relations between Host and Parasite in the Bromes and their Brown Rust, Puccinia dispersa (Erikss.)

Abstract: Ward.-On Relations between Host and Parasite 2. THE RUSTS OF THE BROMES. In their book on the Rusts of the Cereals, published in 1896 \ Eriksson and Henning gave detailed descriptions of six species of Puccinia. Of these four also occur on various species of Bromus.
