This study identifies RALF signaling as a regulator of thermotolerant pollen tube growth in tomato, showing that RALF peptides repress germination at normal temperatures but are antagonized by heat stress.

The paper introduces TubeTracker, a semi-automated tool for analyzing pollen performance parameters, and validates its accuracy in tomato cultivars.

This study identifies how enhanced pollen tube growth under high temperature contributes to thermotolerant fruit production in tomato by analyzing transcriptomic responses and key molecular mechanisms.

The paper identifies a hypothalamic feedback circuit involving UBE3A and the NRXN1-CBLN1-GluD1 complex that regulates aggression, showing how autism-related genetic defects impair this circuit.

The paper examines Connexin36 expression in the cochlear nucleus of echolocating bats and mice, finding conserved gap junction distribution despite differences in temporal processing abilities.

The paper identifies two enhancers critical for TAAR gene expression in olfactory sensory neurons and shows they operate in cis to regulate gene choice.

The paper investigates calcium ion oscillations in synergid cells during pollen tube reception, identifying a critical role in blocking interspecific hybridization.
