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 neurophysiological dogma in the animal kingdom, this review by Barbosa-Caro and Wudick illuminates…

Review: The era of panomics-driven gene discovery in plants

Panomics, an approach integrating multiple ‘omics’ datasets such as genomics, transcriptomics, metabolomics, and phenomics, has seen rapid advancement in recent years due to technological improvements, particularly in genomics. This review focuses on the recent developments in panomics-driven gene…

 De novo domestication: What about the weedy relatives?

Because much of the genetic diversity of our crops plants was lost during domestication, many breeding efforts endeavor to cross in resilience genes from wild relatives. An alternative approach is to rapidly domesticate those wild relatives themselves, for example by editing genes that affect flowering…

How stems breathe: Oxygen production in woody stems under different light conditions

In woody plants, we know much less about how photosynthesis functions in stems than in leaves. This study by Natale et al. focused on how chloroplasts in Fraxinus ornus stems of different ages work. The authors looked at oxygen production rates in whole stems, bark, and wood using various methods like…

CAM evolution is associated with gene family expansion in an explosive bromeliad radiation

Studies on Crassulacean Acid Metabolism (CAM) plant genomes are scarse and CAM evolution is known to be an ecological driver of diversification. The subgenus Tillandsia (Bromeliaceae) is one of the fastest diversifying clades in the plant kingdom and is known for its adaptive CAM trait. It has recently…

Triacylglycerol remodeling to synthesize unusual fatty acids in plants

Plant oils, composed of fatty acids, provide humans and animals with food, essential nutrients, chemicals, and biofuels. Plants accumulate over 450 “unusual” fatty acids, which could hold significant value if they achieve optimal production. Hydroxylated fatty acids (HFA) are unusual fatty acids…

A novel BZR/BES transcription factor controls the development of haploid reproductive organs in Marchantia polymorpha

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.…

Transcriptional changes during barley grain development

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…

Antibody array-based proteome approach reveals proteins involved in grape seed development

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…
