Ancient hybridization underlies tuberization and radiation of the potato lineage Genomic and functional analyses reveal that the potato lineage originated from a homoploid interspecific hybridization event between the Tomato and Etuberosum lineages 8–9 million years ago. The alternate inheritance of highly divergent parental alleles drove the origin of tubers and explosive species diversification and niche expansion into the high Andes.

Plants "bleed" too, but through gases!
When wounded, ethylene leaks out and oxygen seeps in. This gas shift acts as an alarm, triggering self-repair to seal the breach. Excited to share our new collaborative work uncovering this clever plant mechanism! Excellent summary here, indulge!

Overview of different cell wall thickenings. (a) Representation of the different lignified cell wall thickenings per cell type. Lignin is shown in magenta, and the cell types of interest are shown in blue. Exodermis: The four patterns of barrier deposition include nonpolar, in which the entire exodermal cell is surrounded by the barrier; Y-shaped, in which the barrier is deposited in a Y-shaped pattern on the anticlinal wall closer to the inner root; polar cap, in which the barrier is polarized to the periclinal cell wall facing the epidermis, forming a cap; and anticlinal, in which the barrier is deposited in the anticlinal walls. Endodermis: The lignified Casparian strip is deposited in the center of endodermal anticlinal walls. Cortical cells: Phi thickenings are found in the radial, transverse walls and can form a net-like set of thickenings. A detailed inset is represented to highlight this net-like structure from a top view perspective of a cell. The sclerenchyma cells (depicted here as is typical of a multiseriate cortical sclerenchyma) have thick lignin that uniformly coats all cell walls. Epidermis: In the velamen, a complex set of secondary cell-wall thickenings is generally oriented in the same direction in each cell. A detailed cell is represented to highlight this oriented cell wall pattern from a top-view perspective.

From the Annual Review of Plant Biology: Root cell wall thickenings vary across species, aiding water transport, strength & stress response. Understanding their genetics may boost resilience. (Alex Cantó-Pastor, Concepcion Manzano and Siobhán M. Brady)
