One of the two gametes from the pollen tube is fertilized with the egg cell to form a zygote that later develops onto the embryo, while another one is either aborted (in Pinus) or may fertilize with other archegonia but never unite with polar nuclei to form endosperm. The mature seed con...
To assess this hypothesis, we analyze PAPS1's impact on pollen-tube growth and directional development. Efficient ovule localization by pollen tubes traversing female tissue is associated with increased PAPS1 expression at the transcriptional level, a phenomenon not observed at the protein level, ...
More tubers Poor flowering Poor pollen production Very common in modern potatoes, 60% or more are T type. Found in 59.4% of European potatoes (Sanetomo 2015) and 72.1% of Japanese potatoes (Hosaka 2012). Rare in Argentina and common in Chile. Not present in the other Andean countries oth...
Packaging materials protect food from degradation by providing various mechanisms, such as avoiding entry to the product, odor transmission prevention, and the conservation of an internal packaging environment [22]. Different containers, including tin cans, clay jars, and glass jars, are used for ...
