The paper investigates calcium dynamics in Arabidopsis ovules during pollen tube reception, showing N-linked glycosylation is required for synergid cell calcium oscillations but not pollen tube reception itself.

This paper develops a live-imaging system to observe the basal region of early Arabidopsis leaf primordia for over 50 hours.

This study shows extracellular calcium affects pollen tube growth and guidance in Arabidopsis by modulating intracellular calcium levels and directional growth.

This study identifies a molecular intermediate state in Cycas revoluta fertilization, showing cycad sperm retain motility features while pollen tubes lack angiosperm-like tip growth mechanisms.

This study shows that brassinosteroids (BRs) function as reproductive hormones in Arabidopsis, regulating gene expression in both male and female reproductive tissues during fertilization.

This study investigates vesicle-mediated pollen tube growth in Torenia fournieri using BFA and AS-ODNs, showing their effects on cell wall morphology and gene expression.

This study shows that brassinosteroids and flavonols enhance pollen tube germination and growth under temperature stress by maintaining ROS homeostasis.

This study identifies HD-ZIP IV genes as essential for radial axis formation in Arabidopsis by regulating apical cell polarization and division orientation.

The paper investigates mitochondrial protein import in Cyanidioschyzon merolae by designing synthetic targeting peptides and showing that basic residues and specific amino acid composition are sufficient for import, with a simplified authentication mechanism involving TOM22.

This paper develops a microfluidic device to detect miR399 in plant extracts for early diagnosis of phosphorus deficiency stress.

The paper shows that oligomerizing AMOR enhances its biological activity and mimics native AMOR's effect on pollen tube capacitation in Torenia fournieri.

This study identifies DROL1 as an Arabidopsis U5 snRNP subunit required for splicing AT-AC-type introns, showing its role in plant growth and development through RNA-Seq analysis of mutants.

The paper introduces CZON-cutter, a CRISPR-Cas9 system for genome editing and organelle visualization in Cyanidioschyzon merolae, enabling validation of essential gene functions.

The paper shows that presynaptic MAST kinase in C. elegans controls bidirectional postsynaptic responses to encode thermal stimulus valence through opposing signals.
