A cDNA clone that encodes a feedback-insensitive anthranilate synthase (AS), ASA2, isolated from a 5-methyl-tryptophan (Trp) (5MT)-resistant tobacco cell line under the control of the constitutive cauliflower mosaic virus 35S promoter, was introduced into the forage legume Astragalus sinicus by

The feedback-insensitive anthranilate synthase ( ASA2) cDNA--isolated from a 5-methyltryptophan (5MT)-resistant tobacco cell line--driven by the CaMV 35S promoter or 606 bp of the native ASA2 promoter, was introduced into the forage legume plant Astragalus sinicus or soybean ( Glycine max), using

Nicotiana tabacum L. (tobacco) plants were transformed to overexpress a selenocysteine methyltransferase gene from the selenium hyperaccumulator Astragalus bisulcatus (Hook.) A. Gray (two-grooved milkvetch), and an ATP-sulfurylase gene from Brassica oleracea L. var. italica (broccoli). Solvent

Leghemoglobins (Lbs) play an important role in legumes-rhizobia symbiosis. Lbs bind O2 and protect nitrogenase activity from damage by O2 in nodules, therefore, they are regarded as a marker of active nitrogen fixation in nodules. Additionally, Lbs are involved in the nitric oxide (NO) signaling

An important traditional Chinese medicine herb, Astragalus membranaceus var. Mongholicus, whose dried root is known as Radix astragali ("Huangqi" in Chinese), has high flavonoid content as an essential active constituent. Phenylalanine ammonia-lyase (PAL, EC 4.3.1.5) catalyzes the first and also a

Medicinal herbs (21 species) were screened for the antioxidant activity and nicotine degradation activity (NDA) in vitro. Eleven of them with higher antioxidant activity and NDA were selected for preparation of the medicinal herb tea (MHT) and the effects of MHT on smoking cessation and reducing
