TL;DR: It is reported that the combined loss of AHA6, AHA8, and AHA9 in Arabidopsis thaliana delays pollen germination and causes pollen tube growth defects, leading to drastically reduced fertility.

TL;DR: In Arabidopsis, it is shown that two zinc transporting P1B-ATPases actively export zinc from the mother plant to the filial tissues, and blockage of zinc transport was observed at both high and low external zinc supplies.
Purifying selection acts on coding and non-coding sequences of paralogous genes in Arabidopsis thaliana
TL;DR: Loss of conserved non-coding sequences in one gene of a paralogous gene pair correlates with reduced expression levels that are more tissue specific, which suggests that similar forces of purifying selection act on coding and non-Coding sequences.
A cis-Regulatory Sequence Acts as a Repressor in the Arabidopsis thaliana Sporophyte but as an Activator in Pollen.
