Cytomixis in plants: causes, mechanisms and consequences
A migração de organelas, produtos gênicos e material genético entre meiócitos por meio de conexões citoplasmáticas ou canais citomíticos é definida como citomixia. Esse fenômeno tem sido relatado em Leguminosae, Brassicaceae, Poaceae, Apocynaceae, Liliaceae, Rutaceae, entre outras famílias, sendo mais comumente observado entre células mãe dos grãos de ...

Meiotic behaviour and morpho-phenological variation in cut stock (Matthiola incana L.) flower
Morpho-phenological and meiotic studies were performed in twelve cultivars of Matthiola incana. All of the cultivars were diploid (2n = 2x = 14) with basic chromosome number x = 7.
