Bands of cellulose in xylem cells of Arabidopsis thaliana
Xylem cells are like drinking straws for plants. Located deep within a plant’s stem, xylem draws water up from the earth and transports it to the rest of the plant. But just like how drinking straws can be bent and clogged, so too can xylem cells. Plants circumvent this problem by scaffolding xylem with thick deposits of cellulose, a tough fibrous material. This genetically engineered plant shows bands of cellulose in xylem cells, underscoring how the crisscross pattern of cellulose supports xylem integrity and prevents its collapse.

Phylogram of the core Goodeniaceae generated from raw contigs of 150bp Illumina paired-end repeats (with the help of the Pires lab) read-mapped to the Helianthus plastome (with the internal repeat removed) by my friend and collaborator Emily Sessa.

Distribution of Goodeniaceae in Australia. Colors correspond to four major biomes/regions: Blue is the Northern Monsoonal tropics, Green is the Southeastern Temperate, Yellow is the Central Eremaeaen, and Red is the Southwestern Australian Floristic Region. Data points represent digitised collection locations of specimens held in Australian herbaria, downloaded from Australia’s Virtual Herbarium (The Council of Heads of Australasian Herbaria 1999–)

Match It Monday!
Plant cells? Algae? Coral? Were you right?
Surprisingly, these are leaf cells from a genetically engineered tobacco plant made to produce fluorescent proteins. Each squiggle shape is an individual plant cell with glowing proteins localizing to the cell periphery. Tobacco was the first genetically modified plant ever to be produced back in 1982, where DNA was altered so the plant became resistant to antibiotics. This was the first stepping stone for the production of all genetically modified crops today, a topic of intense debate in biology, economics, ethics, and government.
