Arabidopsis thaliana  (L.) Heyn.

Mouse-Eared Cress

Arabidopsis thaliana plant

Family - Brassicaceae

Habit - Taprooted annual forb.

Stems - Ascending to erect, to 50 cm, branched or unbranched, single or multiple from the base, apically glabrous, basally pubescent with branched and unbranched hairs.

Arabidopsis thaliana stem Stem.

Leaves - Basal and alternate. Basal leaves in a rosette, spatulate, petiolate, entire or shallowly dentate, to 6 cm long, with branched hairs, rounded at the apex. Stem leaves to 3 cm, sessile, not clasping stem, simple, entire, ciliate-margined, surfaces with some branched hairs, elliptic, rounded at the apex, relatively few (2-6) per stem.

Arabidopsis thaliana basals Basal rosette.

Arabidopsis thaliana basals2 Basal leaves, abaxial.

Arabidopsis thaliana leaf2 Stem leaf, abaxial.

Inflorescence - Terminal and axillary racemes, compact in flower, elongated in fruit to 15 cm. Pedicels to 1 cm long in fruit, glabrous, glaucous.

Flowers - Sepals 4, 1.0-2.0 mm long, ascending, oblong, hairy. Petals 4, white, glabrous, spatulate, to 4 mm long, rounded at the apex. Stamens 6, erect. Filaments white, glabrous, 2.5 mm long. Anthers yellow, 0.3 mm long. Ovary cylindric, green, glabrous, superior, 2 mm long in fruit. Style to 0.5 mm.

Arabidopsis thaliana calyces Calyces

Arabidopsis thaliana flowers Corollas.

Fruits - Siliques spreading to ascending, nearly straight, to 1.8 cm long, to 20 times as long as wide, terete, glabrous, many-seeded, beaked, each valve with a midnerve. Seeds in 1 row in each locule, 0.3-0.5 mm long, oblong in outline, the surface with a fine, netlike or honeycomblike pattern of ridges and pits to nearly smooth, orange.

Arabidopsis thaliana fruits2 Immature fruits.

Flowering - April - May.

Habitat - Open sandy ground, rocky open ground, fallow fields, pastures, roadsides, railroads.

Origin - Native to Europe.

Other info. - This small and inconspicuous species can be found mostly in the southern half of Missouri. It is also found in scattered locations throughout the U.S., predominantly in the Northeast and along the west coast. The plant is fairly wispy and indistinct but can be identified by its thin siliques, small white flowers, basal rosette with branched hairs, and hairy (near the base) stems. A. thaliana is used widely in experiments on plants due to its small size, short life cycle, and relatively simple genome.

Photographs taken in Brown Summit, NC., 3-13-03, and 4-6-03, and in Auburn, AL., 2-19-05 (DETenaglia); also near Labadie, Franklin County, MO, 4-8-2016 (SRTurner).

4. Arabidopsis thaliana (Linnaeus) Heynhold in F. Holl and G. Heynhold, Fl. Sachsen. 1: 538. 1842.

Thale cress

Arabis thaliana Linnaeus, Sp. Pl. 2: 665. 1753; Sisymbrium thalianum (Linnaeus) J. Gay & Monnard

Annuals ; glabrous or pubescent, trichomes usually simple, sometimes mixed with stalked, forked ones. Stems simple or few from base, erect, unbranched or branched distally, (0.2-)0.5-3(-5) dm, pubescent basally, trichomes predominantly simple, glabrous apically. Basal leaves shortly petiolate; blades obovate, spatulate, ovate, or elliptic, 0.8-3.5(-4.5) cm × (1-)2-10(-15) mm, margins entire, repand, or dentate, apex obtuse, adaxial surface with predominantly simple and stalked, 1-forked trichomes. Cauline leaves subsessile; blade lanceolate, linear, oblong, or elliptic, (0.4-)0.6-1.8(-2.5) cm × 1-6(-10) mm, margins usually entire, rarely toothed. Fruiting pedicels divaricate, 3-10(-15) mm. Flowers: sepals 1-2(-2.5) mm, lateral pair not saccate basally, (glabrous or sparsely pubescent distally, trichomes simple); petals white, spatulate, 2-3.5(-4) × 0.5-1.5 mm, (base attenuate to claw); filaments 1.5-2 mm. Fruits cylindric or linear, smooth, terete, (0.8-) 1-1.5(-1.8) cm × 0.5-0.8 mm; valves each with distinct midvein; ovules 40-70 per ovary; style to 0.5 mm. Seeds light brown, (plump), ellipsoid 0.3-0.5 mm; cotyledons incumbent. 2 n = 10.

Flowering Feb-May. Sandy areas along roadsides, stream banks, railroad tracks and embankments, open pastures, grassy flats, fields, prairies, floodplains, woods, lawns, limestone ledges and crevices, bluffs, shale and serpentine barrens, gravel, sandstone; 0-1000 m; introduced; B.C., Ont., Que.; Ala., Ark., Calif., Conn., Del., D.C., Ga., Idaho, Ill., Ind., Iowa, Ky., La., Maine, Md., Mass., Mich., Miss., Mo., Mont., N.H., N.J., N.Y., NC., Ohio, Okla., Oreg., Pa., R.I., S.C., Tenn., Tex., Utah, Vt., Va., Wash., W.Va., Wis.; Europe; sw, c Asia; introduced also nearly worldwide.

Arabidopsis thaliana is the most widely used model organism in plant biology. Its small genome size, fully sequenced in the year 2000, chromosome number, fast growth cycle (from seed germination to set in four to six weeks), small size (hundreds can be grown in a pot and thousands in a growth chamber), autogamous breeding system (induced mutations are expressed in two generations), and ability to grow on various synthetic media, all make the species an ideal system in experimental biology.
