McKently A, Moore G, Doostdar H, Niedz R
Plant Cell Rep . 2013 Nov; 14(11):699-703. PMID: 24186625
Transgenic peanut (Arachis hypogaea L.) plants have been produced using an Agrobacterium-mediated transformation system. Zygotic embryo axes from mature seed were cocultured with Agrobacterium tumefaciens strain EHA101 harboring a binary...

Mariasegaram M, Chase Jr C, Chaparro J, Olson T, Brenneman R, Niedz R
Anim Genet . 2007 Jan; 38(1):54-9. PMID: 17257189
The ability to maintain normal temperatures during heat stress is an important attribute for cattle in the subtropics and tropics. Previous studies have shown that Senepol cattle and their crosses...

Nairn C, Niedz R, Hearn C, Osswald W, Mayer R
Biochim Biophys Acta . 1997 Mar; 1351(1-2):22-6. PMID: 9116036
A citrus cDNA encoding a class II acidic chitinase was isolated from a nonembryogenic cell line of sweet orange using the tobacco cDNA clone PROB3. Northern blot analysis revealed that...

Mayer R, McCollum T, Niedz R, Hearn C, McDonald R, Berdis E, et al.
Planta . 1996 Jan; 200(3):289-95. PMID: 8931350
Seven endochitinases (EC 3.2.1.14) (relative molecular masses 23,000-28,000 and isoelectric points 10.3-10.4) were purified from nonembryogenic Citrus sinensis L. Osbeck cv. Valencia callus tissue. The basic chitinase/lysozyme from this tissue...

Osswald W, Shapiro J, Doostdar H, McDonald R, Niedz R, Nairn C, et al.
Plant Cell Physiol . 1994 Jul; 35(5):811-20. PMID: 7952962
Acidic chitinases (EC 3.2.1.14) were isolated and characterized from 4-week-old nonembryogenic Citrus sinensis L. Osbeck cv 'Valencia' callus tissue. The enzymes were purified using size exclusion, anion exchange, and chromatofocusing...

Osswald W, McDonald R, Niedz R, Shapiro J, Mayer R
Anal Biochem . 1992 Jul; 204(1):40-6. PMID: 1514694
A quantitative fluorometric assay for chitosanase activity in bacterial and plant tissues was developed. The assay can be conducted with either finely milled preparations of chitosan in suspension or dissolved...
