Chromosome segregation in plant meiosis [PDF]
, 2014 Faithful chromosome segregation in meiosis is essential for ploidy stability over sexual life cycles. In plants, defective chromosome segregation caused by gene mutations or other factors leads to the formation of unbalanced or unreduced gametes creating

Plant Direct, Volume 8, Issue 1, January 2024.Abstract Recently, the siRNAs pathways, and especially reproductive phasiRNAs, have attracted attention in eudicots since their biological roles are still unknown and their biogenesis took different evolutionary pathways compared to monocots. In this work, we used Coffea arabica L., a recent allotetraploid formed from the hybridization of Coffea ...

Genome‐Wide Characterization and Analysis of the SPL Gene Family in Eucalyptus grandis
International Journal of Genomics, Volume 2024, Issue 1, 2024.SQUAMOSA promoter‐binding protein‐like (SPL) gene family, a group of plant‐specific transcription factors, played crucial roles in regulating plant growth, development, signal transduction, and stress response. This study focuses on the SPL gene family in the fast‐growing Eucalyptus grandis, employing bioinformatics approaches to identify and analyze ...
