Pollen aperture patterning in Arabidopsis is controlled by members of the ELMOD protein family, whose expression levels in developing pollen lineage are tightly regulated.

KATANIN1 in stigma papilla cells prevents disordered pollen tube growth and straightens pollen tube direction, allowing the pollen tube to find its correct path to the underlying female tissues.

Recent findings about the possible intercellular signalling role of glutamate, GABA, and melatonin might help to establish hypotheses concerning the evolutionary factors that caused intercellular organisms to use specific molecules in intercellular signalling.

Flowers did bloom in the Early Jurassic.

Building on previous work (Kessler et al., 2015), it is shown that long-tongued hawkmoths assess individual flowers by smelling floral odors with olfactory neurons on their proboscises, and that this close-range perception is crucial for successful pollination and foraging.

Molecular signals from chloroplasts can synergistically interact with the plant hormone, abscisic acid (ABA), to regulate non-canonical signaling pathways mediating fundamental cellular processes including stomatal closure, seed dormancy and germination.

Cation chloride cotransporter CCC1 has a central function in plant cells and is the missing ion efflux component of the transport circuit necessary to regulate pH in the lumen of the trans-Golgi-network/early endosome, the major cargo hub in plant cells.

Inbreeding compromises floral traits and reduces pollinator visitation rates disproportionally in female relative to male individuals in a dioecious plant and may thus interfere with the equilibrium of a complex co-evolutionary plant-insect relationship.

Cytological and biochemical analyses reveal Arabidopsis formin 2 is involved in regulating PD permeability by anchoring actin filaments to PD and stabilizing them through actin filament barbed end capping activity.

The Arabidopsis N6-methyladenosine (m⁶A) binding proteins ECT2 and ECT3 act redundantly in the cytoplasm to regulate m⁶A-containing mRNAs whose abundances are reduced in ect2/ect3/ect4 knockout plants although the locations of their polyadenylation sites remain unaffected, contrary to currently held beliefs.
