Cypress Surrogate Mother Produces Haploid Progeny From Alien Pollen

Cypress surrogate mother produces haploid progeny from alien pollen.

Although most living organisms reproduce sexually, some have developed a uniparental reproduction where the embryo usually derives from the female parent. A unique case of paternal apomixis in plants has been recently reported in Cupressus dupreziana, an endangered Mediterranean conifer. This species produces unreduced pollen that develop into all-paternal embryos within the seed tissues. We an...

Cypress pollen allergy is responsible for two distinct phenotypes of allergic rhinitis different from other pollinosis.

Summary Different phenotypes of allergic rhinitis have been identified based on the seasonality of the allergen involved. Within pollinosis, importance has to be paid to the responsible pollen species. Guidelines for clinical management are mostly based on studies performed in patients with grass pollen allergy. Only few data is available on tree pollen allergy and more specifically on cypress ...
