7.1 Reinforcement
... There are two types of chromosomes: autosomes and sex chromosomes. Genes on the sex chromosomes determine an organism’s sex. Autosomes are all of the other chromosomes, and they do not directly affect sex determination. Gene expression can differ depending on the type of chromosome on which a gene i ...

AGO1-IP approach to small RNA target discovery in Arabidopsis
... A drawback of the method is its intrinsic reliance on sufficient VSR expression levels in the tissues of interest. This may partly explain its poor performances in roots (Figure S5), where the 35S promoter is reputed to be only weakly active in several cell layers. Constitutive VSR expression might ...
