Control of Plant Growth and Defense by Photoreceptors: From Mechanisms to Opportunities in Agriculture
(Oxford University Press, 2021-01)
Plants detect and respond to the proximity of competitors using light signals perceived by photoreceptor proteins. A low ratio of red to far-red radiation (R:FR ratio) is a key signal of competition that is sensed by the ...
Epichloë Fungal Endophytes and Plant Defenses: Not Just Alkaloids
(Elsevier Science London, 2017-11)
Although the role of fungal alkaloids in protecting grasses associated with Epichloë fungal endophytes has been extensively documented, the effects of the symbiont on the host plant's immune responses have received little ...
Effects of nitric oxide on sunflower seedlings: a balance between defense and development
(Taylor & Francis, 2015-04)
Nitric oxide (NO) is a major plant signaling molecule that plays key roles during plant-pathogen interactions and plant development. Previous work showed the participation of NO in the development and lignin composition ...
Bordetella pertussis modulates human macrophage defense gene expression
(Oxford University Press, 2016-08)
Bordetella pertussis, the etiological agent of whooping cough, still causes outbreaks. We recently found evidence that B. pertussis can survive and even replicate inside human macrophages, indicating that this host cell ...
Calcium chloride treatment modifies cell wall metabolism and activates defense responses in strawberry fruit (Fragaria × ananassa, Duch)
(John Wiley & Sons Ltd, 2019-06)
BACKGROUND: Fruit dips in calcium ions solutions have been shown as an effective treatment to extend strawberries (Fragaria × ananassa, Duch) quality during storage. In the present work, strawberry fruit were treated with ...
Salicylic acid Is involved in the Nb-Mediated defense responses to potato virus X solanum tuberosum
(American Phytopathological Society, 2010-04)
To evaluate the role of salicylic acid (SA) in Nb -mediated hypersensitive resistance to Potato virus X (PVX) avirulent strain ROTH1 in Solanum tuberosum, we have constructed SA-deficient transgenic potato plant lines by ...
Regionalism and security: the case of Mercosur and the absence of defense issuesRegionalismo y seguridad: El caso del mercosur y la ausencia de los temas de defensa
(Universidade Federal do Rio Grande do Sul, 2019-06)
A pesar de haber sido creado bajo una impronta económico-comercial, el Mercosur fue incorporando otras áreas de cooperación durante sus primeros años. Salud, Trabajo o Medio Ambiente fueron algunas de ellas. Sin embargo, ...
Potassium phosphite primes defense responses in potato against Phytophthora infestans
(Elsevier Gmbh, 2012-06-22)
Although phosphite is widely used to protect plants from pathogenic oomycetes on a wide range of horticultural crops, the molecular mechanisms behind phosphite induced resistance are poorly understood. The aim of this ...
Long-day photoperiod enhances jasmonic acid-related plant defense
(American Society of Plant Biologist, 2018-09)
Agricultural crops are exposed to a range of daylengths, which act as important environmental cues for the control of developmental processes such as flowering. To explore the additional effects of daylength on plant ...
Potato Snakin-1: an antimicrobial player of the trade-off between host defense and development
(Springer, 2020-07)
Snakin-1 (SN1) from potato is a cysteine-rich antimicrobial peptide with high evolutionary conservation. It has 63 amino acid residues, 12 of which are cysteines capable of forming six disulfide bonds. SN1 localizes in the ...
