Abstract:
... Abiotic stress affects metabolic processes in plants and restricts plant growth and development. In this experiment, Caucasian clover (Trifolium ambiguum M. Bieb.) was used as a material, and the CDS of TaMYC2, which is involved in regulating the response to abiotic stress, was cloned. The CDS of TaMYC2 was 726 bp in length and encoded 241 amino acids. The protein encoded by TaMYC2 was determined ...

Kura clover (Trifolium ambiguum) is a perennial living mulch species that can be used in conjunction with zone tillage to reduce nitrogen pollution, maintain ground cover, and provide nitrogen to crops. In such systems, kura clover is maintained between crop rows by limiting tillage only to within-row areas. However, the effect of zone-tilled living mulches on soil quality and nutrient cycling in ...

Abstract:
... BACKGROUND: Trifolium ambiguum occurs as a 2x, 4x, 6x polyploid series in W Asia. The 6x form is the most agronomically desirable, having strong rhizomatous spread and drought tolerance. These traits would be potentially very valuable if they could be transferred to white clover (T. repens) which is the most important agronomic clover species. However, to-date, no fertile interspecific hybrids wit ...
