Characterization of meiotic chromosome behavior in the autopolyploid Saccharum spontaneum reveals preferential chromosome pairing without distinct DNA sequence variation
《The Crop Journal》2023年第5期1550-1558,共9页Xin Zhang Zhuang Meng Jinlei Han Haris Khurshid Ayman Esh Robert Hasterok Kai Wang

Autopolyploidy and allopolyploidy may represent an evolutionary advantage and are more common in plants than assumed. However, less attention has been paid to autopolyploidy than to allopolyploidy,and its evolutionary...

Genome structure and apomixis in Phoenicaulis(Brassicaceae;Boechereae)
《Journal of Systematics and Evolution》2021年第1期83-92,共10页Terezie Mandakova Kaylynn Ashby Bo J.Price Michael D.Windham John G.Carman Martin A.Lysak 
This article is dedicated to Dr.Ihsan A.Al-Shehbaz(Missouri Botanic Garden)on the occasion of his 80th birthday.This work was supported by Czech Ministry of Education,Youth and Sports within the program INTER-EXCELLENCE(project No.LTAUSA17002),by the CEITEC 2020 project(grant No.LQ1601 to MAL),the Utah Agricultural Experiment Station project awards,Utah State University,Logan to JC,and the U.S.National Science Foundation(award DEB-0816560 to MDW).
Apomixis in crucifer(Brassicaceae)species is rare,reported in just four genera(Boechera,Draba,Erysimum,and Parry a),and one intergeneric hybrid(Raphanobrassica).It is well studied only in Boechera,where it is widespre...

Phylogenetic and cytogenetic studies reveal hybrid speclatlon in Saxifraga subsect. Triplinervium （Saxifragaceae）
