Autopolyploidization‐Induced Chromatin Remodeling Regulates Leaf Size Variation in Brassica rapa

open access: yesAdvanced Science, EarlyView.
This study demonstrates that monoploid, diploid, and autotetraploid Brassica rapa lines derived from the same genome exhibit distinct leaf morphology. Ploidy changes remodel chromatin accessibility and histone modifications to regulate gene expression, while key transcription factors BrGRF13 and BrARF11 control leaf size and polarity, driving ...

Present Status of the Repeat-Breeder Cow Problem

open access: yesJournal of Dairy Science, 1961
Summary A repeat-breeder is defined as a clinically normal cow which, other factors being optimal, shows a reduced probability of conception. Both fertilization failure and embryonic loss are major causes of repeat-breeding. Much of the embryonic loss occurs between Days 16 and 25 after breeding.

Mitochondrial genetics of alloplasmic male-sterile Brassica napus lines [PDF]

open access: yes, 2005
Reliable and economical production of hybrid (F1) varieties requires efficient means to control pollination. The predominant system for pollination control of most field crops today is cytoplasmic male sterility (CMS).
