A finely dispersed, homogeneous and highly chlorophyllous cell suspension (TIANSJ98 cell line) was obtained from shoot apices of Bouteloua gracilis (H.B.K.) Lag. ex Steud. cultured on MPC medium containing MS salts supplemented with 2,4-D (1 mg/l), BAP (2 mg/l) and adenine (40 mg/l). When the
For the first time, the production of transgenic plants of the forage grass blue grama, Bouteloua gracilis [H.B.K.] Lag. ex Steud., is reported. Transgenic plants containing a gus Colon, two colons nptll fusion driven by a double CaMV35S promoter were obtained by microprojectile bombardment of the
We have developed a new chlorophyllic cell line ('TADH-XO') from the highly water stress tolerant grass Bouteloua gracilis (blue grama). When grown under normal (non-stress) conditions, this new cell line accumulates higher levels of chlorophyll (up to 368.1 microg total chlorophyll g(-1) FW) than a
OBJECTIVE
Productivity in drylands may depend on the sensitivity of interactions between plants and biocrusts. Given future climate variability, it is essential to understand how interactions may be context-dependent with precipitation regime. Furthermore, little is known about the additional
The temperatures at which chlorophyll fluorescence yield is substantially increased and the temperatures at which the quantum yield for CO2 uptake is irreversibly inhibited were measured for three shortgrass prairie species. The experimental taxa include, a cool season species (Agropyron smithii), a
Several aspects of photosynthetic adaptation to temperature were examined in four graminoid species from the Colorado shortgrass steppe. The experimental species were chosen to provide examples of a variety of in situ seasonal phenology patterns. The cool season grass, Agropyron smithii (C3),
