Wild pea

A temperature-sensitive dominant allele Sym, has been identified in the wild pea cultivar Iran (Lie, 1984). Certain strains of R. leguminosarum would not nodulate at 20°C, but after a brief exposure of plants to 26°C nodulation occurred.

Laboratory and domestic animals may be poor models for avoidance of predator odors. For example, in one experiment, chickpeas were painted with the sulfur compounds w-propyldithiolane and w-propylthiolane from stoat anal gland secretion and 2,4,5-trimethylthiazoline (Fig. 3.1, p. 37) from fox feces. The chickpeas were planted and wild mice and house mice were tested to see if they would dig up and eat the peas. Wild mice remembered the predator odors better after odor exposure for 1 or 4 weeks and, consequently, may be better than laboratory mice at risk assessment (Coulston etal, 1993).

The experiments have been performed on a setup that used the ps-OPO-based CARS system described above and a femtosecond Tiisapphire laser in conjunction with a commercial laser scanning microscope (Carl Zeiss, model LSM-510). The peripheral nerve samples were gained from C57/B6 wild-type mice. After removing the skin from the lower extremities from freshly sacrificed mice, the saphenous nerve is exposed as it runs very conveniently for excision along the saphenous vein, without too much additional fatty tissue and a favorable tissue thickness of less than 20 m. A 500- m long piece is excised and freed from additional fatty tissue as well as the collagenous nerve sheath. The myelinated nerve tissue is fixed for 3-5 hr in 4% PEA or 10% formalin and mounted on 100-pm thick coverslips that are treated with 3-aminopropyltriethoxysilane or a chromium potassium sulfate solution.

Mutation has been essential to Mendelism at every step, not only as the source of heritable variations-round peas or wrinkled, vermillion eyes or the wild type, rough plaque or smooth-but as a tool for understanding. -Horace Freeland Judson, The Eighth Day of Creation... 

There is limited commercial production of the jequirity bean. The rosary pea is grown as an ornamental plant and has escaped into the wild in the warmer climate in the USA. 

Initially, the BR bios mthetic pathway was elucidated in Catharanthus roseus cell cultures by analysing the conversion products and intermediates (Fujioka et al, 1997). More recently, the biosynthesis of BRs has mainly been studied in Arabidopsis thaliam. Many of the genes encoding BR biosynthetic enzymes have been cloned using BR biosynthesis mutants of Arabidopsis thaliana, pea, tomato and rice. These mutants are BR deficient and revert to a wild-type phenotype following treatment with exogenous BRs.
