What bacterial strain is isolated in the healthy 10-day-old variety of maize with a high sugar content?
Sweet corn Sweet corn ("Zea mays" convar. "saccharata" var. "rugosa"; also called sugar corn and pole corn) is a variety of maize with a high sugar content. Sweet corn is the result of a naturally occurring recessive mutation in the genes which control conversion of sugar to starch inside the endosperm of the corn kernel. Unlike field corn varieties, which are harvested when the kernels are dry and mature (dent stage), sweet corn is picked when immature (milk stage) and prepared and eaten as a vegetable, rather than a grain. Since the process of maturation involves converting sugar to starch, sweet corn stores poorly and must be eaten fresh, canned, or frozen, before the kernels become tough and starchy.
Piriformospora Piriformospora is a fungal genus of the order Sebacinales. It is a monotypic genus, containing the single endophytic root-colonising species Piriformospora indica, discovered from orchid plants in the Thar desert in Rajasthan, India by Prof. Ajit Verma and group, School of Life Sciences, Jawaharlal Nehru University, New Delhi. The fungus has typical pear-shaped chlamydospores, and thus, named as "P. indica ". Unlike mycorrhizal fungi, which cannot be cultured axenically, "P. indica" can be easily grown on various substrates. It has been found to promote plant growth during its mutualistic symbiotic relationship with a wide variety of plants. Experiments have shown that "P. indica" increases the resistance of colonized plants against fungal pathogens. It has also been found in experiments with barley that "P. indica"-inoculated plants are tolerant to salt stress and more resistant to root pathogens. "P. indica"-infested roots also show antioxidant capacity. The fungus also induces systemic disease resistance in plants. "P. indica" was found to require host cell death for proliferation during mutualistic symbiosis in barley. Its genome has been sequenced and was published in 2011.
