Within-plant allocation of a chemical defense in Secale cereale. Is concentration the appropriate currency of allocation?
(Birkhauser Verlag Basel, 1999)
The among-leaves allocation of DIBOA, a hydroxamic acid associated with plant resistance, in the shoot of rye (Secale cereale) was evaluated over the vegetative development of the plant. The appropriateness of using the ...
Induction of defensive response in Eucalyptus globulus plants and its persistence in vegetative propagation
(2013)
The expression of defensive compounds derived from secondary metabolism in plants of Eucalyptus globulus Labill, and the persistence of these in vegetative propagation was evaluated by gas chromatography with flame ionization ...
Hydroxamic acids derived from 2-hydroxy-2h-1,4-benzoxazin-3(4h)-one: Key defense chemicals of cereals
(2009)
Many cereals accumulate hydroxamic acids derived from 2-hydroxy-2H-1,4- benzoxazin-3(4H)-one. These benzoxazinoid hydroxamic acids are involved in defense of maize against various lepidopteran pests, most notably the ...
Inter-regional variation on leaf surface defenses in native and non-native Centaurea solstitialis plants
(Elsevier, 2015)
Plant chemical defenses can be qualitative (toxins) to face generalist herbivores and quantitative (digestibility reducers) to specialists. Trichomes can produce chemicals, but also acts as a quantitative defense and in ...
Effect of host defense chemicals on clonal distribution and performance of different genotypes of the cereal aphid Sitobion avenae
(2004)
Five microsatellite loci were used to study the genetic variability and population structure of Sitobion avenae (Hemiptera: Aphididae) on some of its host plants. Individuals were collected in Chile from different cultivated ...
Dimboa glucoside, a wheat chemical defense, affects host acceptance and suitability of Sitobion avenae to the cereal aphid parasitoid Aphidius rhopalosiphi
(Springer New York LLC, 1998)
The influence of hydroxamic acids (Hx), plant secondary metabolites associated with aphid resistance in wheat, on the host acceptance and suitability of the aphid Sitobion avenae to the cereal aphid parasitoid Aphidias ...
Chemical basis of nestmate recognition in a defense context in a one-piece nesting termite
(2016)
Nestmate recognition is a necessary capacity for the occurrence of discrimination between nestmate and non-nestmate individuals. In one-piece nesting termites, which nest and forage in a single piece of wood, nestmate ...
Activation of early defense signals in seedlings of nicotiana benthamiana treated with chitin nanoparticles
(MDPI, 2020)
Chitin is an excellent material for the synthesis of nanoparticles because it is an elicitor and can form nanostructured materials. The application of chitin nanoparticles (CNPs) in plants can activate early defense responses ...
Environmental effects on the accumulation of hydroxamic acids in wheat seedlings: The importance of plant growth rate
(Springer New York LLC, 1997)
The effects of temperature and photoperiod on accumulation of hydroxamic acids (Hx) in wheat (Triticum aestivum L.) seedlings were evaluated under laboratory conditions. Hx concentrations were significantly higher at higher ...
Unusual Oxidative Dealkylation Strategy toward Functionalized Phenalenones as Singlet Oxygen Photosensitizers and Photophysical Studies
(Amer Chemical, 2020)
A series of functionalized 6-alkoxy phenalenones was prepared through an unprecedented oxidative dealkylation of readily available phenalene precursors. The starting phenalenes were efficiently synthesized via an aminocatalyzed ...
