Gametophyte interaction and sexual reproduction: how plants make a zygote
Boavida, L.C.; Vieira, A.M.; Becker, J.D.; Feijó, J.A.The evolutionary success of higher plants relies on a very short gametophytic phase, which underlies the sexual reproduction cycle. Sexual plant reproduction takes place in special organs of the flower: pollen, the male gametophyte, is released from the anthers and then adheres, grows and interacts along various tissues of the female organs, collectively known as the pistil. Finally, it fertilizes the female ga...
Transcriptional profiling of arabidopsis tissues reveals the Unique Characteris...
Becker, J.D.; Boavida, L.C.; Carneiro, J.; Haury, M.; Feijó, J.A.Pollen tubes are a good model for the study of cell growth and morphogenesis because of their extreme elongation without cell division. Yet, knowledge about the genetic basis of pollen germination and tube growth is still lagging behind advances in pollen physiology and biochemistry. In an effort to reduce this gap, we have developed a new method to obtain highly purified, hydrated pollen grains of Arabidopsis ...
