Haematococcus lacustris: the makings of a giant-sized chloroplast genome
Recent work on the green alga Haematococcus lacustris uncovered the largest plastid genome on record: a whopping 1.35 Mb (with >90% non-coding DNA)

Root hair abundance impacts cadmium accumulation in Arabidopsis thaliana shoots
Root hairs increase the contact area of roots with soil and thereby enhance the capacity for solute uptake. The strict hair/non-hair pattern of Arabidopsis

Stomatal clusters of Begonia reveal eudicot-specific developmental patterns
In the pantropical eudicot genus Begonia (Begoniaceae), non-contiguous clusters of helicocytic stomata develop from an inwardly spiralling series of amplifying divisions and secondary meristemoids that

Abscisic acid inhibits hypocotyl elongation acting on gibberellins, DELLA proteins and auxin
Hypocotyl elongation of Arabidopsis seedlings is influenced by light and numerous growth factors. Light inhibits hypocotyl elongation (photomorphogenesis), whereas elongation is promoted in the dark (skotomorphogenesis)

Subsidiary cell formation in Poaceae stomatal complexes
Polarisation and asymmetrical division generating the Poaceous subsidiary cells constitutes a very attractive model for the study of local intercellular stimulation. Auxin operates as an inductive

Regulatory networks controlling the development of the root system and the formation of lateral roots
The production of a new lateral root from parental root primary tissues has been investigated extensively, and the most important regulatory mechanisms are now well known.

Morphological responses of plant roots to mechanical stress
As they push their way through the soil, roots are continuously exposed to mechanical pressure. This often results in their morphological modification. Most obvious are changes

Can carnivorous plants control an invasive hornet?
Betteridge’s law of headlines states: “Any headline that ends in a question mark can be answered by the word no.” But some scientists in France have tested Sarracenia to find the answer is more like ‘not yet’.

Actin cytoskeleton, plant growth and development in Arabidopsis root hair mutant der1-3
The DER1 (deformed root hairs1) locus encodes a major vegetative actin (ACTIN2) in Arabidopsis thaliana. Mutations in DER1 lead to impaired root hair development. However, the

Effects of growth under different light spectra on subsequent high light tolerance in rose plants
Light is the original source of energy for plant photosynthesis and growth, but it also acts as a signal for morphogenesis and many other physiological processes.

Lateral root initiation and formation in Cucurbita pepo: is auxin a key player?
In most plant species, initiation of lateral roots occurs above the elongation zone. However, in Cucurbitaceae it takes place in the parental root meristem. Ilina et
