Gametogenesis is essential for sexual reproduction. In bryophytes, lycophytes, and ferns, gametogenesis takes place in gametangia: antheridia for sperm production and archegonia for egg production. How these specialized reproductive organs develop at the molecular level remains unclear. Furuya et al.…

Barley is a globally important cereal crop, so understanding barley grain development is of much interest. Here, Kovacik et al. investigated transcriptional changes in barley grains at five points across development, 4, 8, 16, 24 and 32 days after pollination. For each time point, grains were manually…

Grape (Vitis vinifera) is a globally cultivated fruit for fresh or processed consumption, and seedless grapes are highly preferred for consumer convenience. In seedless grapes, fertilization occurs but the embryo subsequently aborts, although the molecular basis for this abortion is not understood. Zhang…

Soil salinization causes massive yield losses in agriculture, and its impact on plants goes beyond what our eyes can see. Roots are immediately affected by the direct exposure to a salt-(NaCl) rich substrate. Here, Zou et al. investigate the salt-induced altered root gravitropic responses in Arabidopsis…

While it is recognized that plant communication, both within and between plants, can be achieved through emission and perception of volatile organic compounds (VOCs), it is unclear exactly how these signals are perceived and transmitted. Stirling et al. tease apart the components of within-plant VOC…

In recent years, single-cell RNA sequencing (scRNA-seq) and single-nuclei RNA sequencing (snRNA-seq) techniques have revolutionized plant biology by enabling the identification of novel cell types, modeling developmental trajectories, and analyzing transcriptional activity at the cellular level. However,…

New technologies, like personal computers or smart phones, often have limited adoption due to their high cost or requirement for advanced technological skills. Greater affordability and ease of use leads to greater adoption. Here, Yu, Sussman et al. describe the development of an affordable, portable…

Review. Revisiting plant electric signaling: Challenging an old phenomenon with new discoveries In the electrifying world of plant signaling, a paradigm shift is underway as researchers dig into the intricate mechanisms of action potentials (APs) and slow wave potentials (SWPs). Departing from conventional…
