“…We describe two basic helix-loop-helix transcription factors that control root hair development in the sporophyte (2n) of the angiosperm Arabidopsis thaliana and rhizoid development in the gametophytes (n) of the bryophyte Physcomitrella patens. …”

Evolution and genetics of root hair stripes in the root epidermis. by Dolan, L, Costa, S

“…The genetic basis for the evolution of epidermal pattern in angiosperms may now be examined.…”

The microRNA FEW RHIZOIDS1 controls rhizoid patterning in the liverwort Marchantia polymorpha by Thamm, A

“…ROOT HAIR DEFECTIVE 6-LIKE (RSL) class I basic Helix-Loop-Helix transcription factors (TFs) positively regulate rhizoid development in bryophytes and root hair development in angiosperms, thus being conserved positive regulators of tip-growing cells with a rooting function in land plants. …”

Investigating glyphosate tolerance mechanisms in the liverwort Marchantia polymorpha by Caygill, SG

“…By expressing MurA in the angiosperm <em>Arabidopsis thaliana</em> and generating <em>murA</em> loss-of-function mutants in <em>M. polymorpha</em>, I determine that MurA confers glyphosate tolerance independently from its function in peptidoglycan biosynthesis. …”

The genetic control of rhizoid development in the liverwort Marchantia polymorpha by Jones, V

“…The homologues of Mp<em>RSL1</em> in the angiosperm <em>Arabidopsis</em> and the moss <em>Physcomitrella</em> control the differentiation of their root hairs and rhizoids, respectively, which suggests that a gene regulatory network that included RSL genes controlled the development of filamentous rooting cells in the last common ancestor of all land plants. …”

Root hairs: development, growth and evolution at the plant-soil interface by Datta, S, Kim, C, Pernas, M, Pires, N, Proust, H, Tam, T, Vijayakumar, P, Dolan, L

“…Finally, we discuss the functional and genetic similarities between the root hairs of angiosperms and the rhizoids of bryophytes and ferns. © 2011 Springer Science+Business Media B.V.…”

Functional PTB phosphate transporters are present in streptophyte algae and early diverging land plants. by Bonnot, C, Proust, H, Pinson, B, Colbalchini, F, Lesly-Veillard, A, Breuninger, H, Champion, C, Hetherington, A, Kelly, S, Dolan, L

“…However, Pi uptake in streptophyte algae and marine angiosperms requires Na(+) influx, suggesting that Na(+) /Pi symporters also function in some streptophytes. …”

LRL genes are ancient regulators of tip-growing rooting cell development in land plants by Tam, HY

“…This suggests that the gene network controlling tip-growing rooting cell development has changed since mosses and angiosperms last shared a common ancestor.…”

miRNA biogenesis and developmental phase transition in the liverwort M. polymorpha by Streubel, S

“…This suggests that HST-regulated phase change operated in the common ancestor of liverworts and angiosperms, one of the first land plants.</p>…”

The development of cell pattern in the root epidermis. by Dolan, L, Roberts, K

“…The root epidermis of most angiosperms is composed of a patterned array of hair and non-hair cells. …”

Early evolution of bHLH proteins in plants. by Pires, N, Dolan, L

“…We have recently shown that the diversity of bHLH proteins in angiosperms is ancient. Most of the bHLH subfamilies present in seed plants such as Arabidopsis thaliana and Oryza sativa are also present in early diverging groups of land plants, including mosses and lycophytes. …”

KATANIN-mediated microtubule severing is required for MTOC organisation and function in Marchantia polymorpha by Attrill, ST, Dolan, L

“…In Arabidopsis thaliana, KTN is required for the organisation of microtubules in the cell cortex, preprophase band, mitotic spindle and phragmoplast. However, as angiosperms lack MTOCs, the role of KTN in MTOC formation has yet to be studied in plants. …”

Root hair development involves asymmetric cell division in Brachypodium distachyon and symmetric division in Oryza sativa. by Kim, C, Dolan, L

“…• The root epidermis of most angiosperms comprises hair (H) cells and nonhair (N) cells. …”

RSL class I genes controlled the development of epidermal structures in the common ancestor of land plants by Proust, H, Honkanen, S, Jones, V, Morieri, G, Prescott, H, Kelly, S, Ishizaki, K, Kohchi, T, Dolan, L

“…Because class I RSL proteins also control the development of rhizoids in mosses and root hairs in angiosperms [13, 14], these data demonstrate that the function of RSL class I genes was to control the development of structures derived from single epidermal cells in the common ancestor of the land plants. …”

RSL genes are sufficient for rhizoid system development in early diverging land plants. by Jang, G, Yi, K, Pires, N, Menand, B, Dolan, L

“…This suggests that auxin might have controlled the development of the first land plant soil anchoring systems that evolved 465 million years ago by regulating the expression of RSL genes and that this regulatory network has changed since mosses and angiosperms last shared a common ancestor.…”

ROOT HAIR DEFECTIVE SIX-LIKE class I genes promote root hair development in the grass Brachypodium distachyon by Kim, C, Dolan, L

“…Taken together these data indicate that that the functions of RSL class I proteins have been conserved among most angiosperms-monocots and eudicots-despite the dramatically different patterns of root hair cell development.…”

Evolution of bHLH transcription factors that control epidermal cell development in plants by Catarino, B

“…Furthermore, I demonstrated that the function of IIIf bHLH TFs in controlling the development of the epidermal cell layer is conserved between liverworts and angiosperms. This suggests that IIIf bHLH TFs are ancient and conserved regulators of epidermal cell development since the early colonization of the land by plants. …”
