bsmv造句

• Plants infected with BSMV are more symptomatic in warmer temperatures.
• The common symptoms for BSMV are yellow streaks or spots, mosaic, leaves and stunted growth.
• BSMV mostly affects regions in Montana and North Dakota and have reduced yields by up to 25 %.
• Common symptoms of BSMV are yellow to white mottling, spotting and streaking, necrosis and severe mosaic on leaves.
• Shortly after its discovery, BSMV was found to be present in 97 % of barley fields in North Dakota in 1954.
• One example of an accomplishment of BSMV gene silencing has been used to detect the location of powdery mildew resistance genes in barley.
• To combat this, in 1957 Kansas, Montana, and North Dakota launched a seed certification program to obtain BSMV free barley seeds.
• BSMV has been known to reduce the yields of barley by up to 25 %, but is not a major problem because of resistant varieties of barley.
• Barley hosts differ in their susceptibility to BSMV . There are many types of resistant barley varieties including : Traill, Moreval, Modjo-1, Morex, Modjo, and CI 4197.
• The control program involved assaying seedlings for presence of the virus, and only seed foundations determined to be BSMV-free were used to produce certified BSMV-free seeds to be sold commercially.
• The control program involved assaying seedlings for presence of the virus, and only seed foundations determined to be BSMV-free were used to produce certified BSMV-free seeds to be sold commercially.
• Symptoms for BSMV are similar to barley stripe disease, a fungal disease caused by " Pyrenophora graminea ", though the two are caused by completely different pathogens and should be treated differently.
• BSMV was the first virus-induced gene silencer found in monocots, which is important because many crops such as corn, rice, rye, sugarcane, sorghum, and the hosts of BSMV are monocots.
• BSMV was the first virus-induced gene silencer found in monocots, which is important because many crops such as corn, rice, rye, sugarcane, sorghum, and the hosts of BSMV are monocots.
• By 1972 a zero tolerance was placed on all certified seeds in Montana which led to a dramatic decline in yield loss due to BSMV . Similarly, in 1971 BSMV was eliminated in barley seeds in North Dakota.
• By 1972 a zero tolerance was placed on all certified seeds in Montana which led to a dramatic decline in yield loss due to BSMV . Similarly, in 1971 BSMV was eliminated in barley seeds in North Dakota.
• However, despite not being a factor in crop production anymore, BSMV is still important in research, as various studies have shown that it can be used to study gene function via gene silencing in oat, wheat, and " Brachypodium distachyon " ( a grass that is a model monocot for genetics research ).
