Abstract A description is provided for Clavibacter michiganensis subsp. tessellarius. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOST: Triticum aestivam. Inoculation into barley, oats, sweet corn, sudan grass, wild rye, smooth brome and tomato resulted in multiplication of bacteria to above 106 CFU/g fresh weight in 10 days, but no symptoms were produced. In wheat higher populations and symptoms were produced. DISEASE: Bacterial mosaic of wheat. Small chlorotic lesions are densely spread over the leaf surfaces, resembling a virus mosaic. GEOGRAPHICAL DISTRIBUTION: USA (AK, NE, IA). TRANSMISSION: The bacterium has been shown to occur in seed under the seed coat near the embryo and was found in the roots, sheaths and leaves of seedlings grown from such seed (McBeath & Adelman, 1986).

Abstract A description is provided for Septoria lactucae. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Lactuca sativa. DISEASE: A minor leaf spot of lettuce (Lactuca sativa). Early symptoms are small, numerous, irregularly outlined, chlorotic spots beginning on the outer leaves. They enlarge, becoming brown or somewhat silvery, sometimes with a chlorotic halo, and shot-holes develop. Pycnidia, which may not be conspicuous, are found on both leaf surfaces. Infection spreads to the younger leaves and flowers in severe attacks (20: 193; 21: 182). GEOGRAPHICAL DISTRIBUTION: Widespread (CMI Map 485, ed. 1, 1972). TRANSMISSION: By seed, pycnidia can be found embedded in the seed coat (41: 267).

History Of

Goss's bacterial wilt and blight, caused by Clavibacter michiganensis subsp. nebraskensis (Cmn), has reemerged as an important disease of Zea mays (corn) in the U.S. Midwest. Results from a 2011 multistate survey indicated that Setaria spp. (foxtail) were often present in corn fields with a history of Cmn. The objective of this research was to determine if Setaria spp. that are common in the Midwest are susceptible to infection by Cmn. In the greenhouse, seedlings of four Setaria spp., including S. viridis (green foxtail), S. faberi (giant foxtail), S. verticillata (bristly foxtail), and S. pumila (yellow foxtail), and Zea mays (Golden Cross Bantam sweet corn, GCB) were inoculated with a suspension of 1.0 × 107 bacteria cells. The trial was arranged in a randomized complete block design and repeated once. Percent of symptomatic leaf area was visually estimated eight days after inoculation. S. faberi exhibited the highest levels of disease among the four Setaria spp., with disease incidence similar to what was observed on Z. mays. S. viridis was the next most susceptible. Symptoms were also observed on S. viridis, S. verticillata, and were lowest for S. pumila. Bacterial streaming was confirmed microscopically and Cmn was reisolated from the four Setaria species. Results indicate that these four Setaria spp. are susceptible to Cmn, thus serving as potential sources of inoculum. Accepted for publication 1 February 2014. Published 28 April 2014.

Abstract A description is provided for Clavibacter michiganensis subsp. nebraskensis. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Zea mays is the natural host. By inoculation Euchlaena mexicana, Saccharum officinarum, Sorghum bicolor, S. sudanense and Tripsacum dactyloides are infected (Schuster et al., 1973). DISEASE: Leaf freckles and wilt, or Goss's bacterial wilt and blight. The disease is characterized by the appearance of discrete, water-soaked spots, dark green to blackish at first, becoming brown and more freckle-like, then coalescing and inducing a leaf scorch. The spots may arise from direct infection or via systemic infection from roots and stems (Schuster et al., 1973). GEOGRAPHICAL DISTRIBUTION: USA (IA, IL, KS, NE). (IMI Distribution Map 549, ed. 1, 1982; 67, 4495). TRANSMISSION: The bacterium can overwinter in debris from diseased corn, particularly stubble and this is a source of primary inoculum in the new growing season. It is also present within the seed where it can remain viable for more than a year. However, experiments suggest that seed transmission is rare (Schuster et al., 1973).

Peanut (Arachis hypogaea) is a crop that can produce resveratrol, a compound with various biological properties, such as those that exert antioxidant, anticancer, and anti-inflammatory effects. In this study, trans-resveratrol was detected in the roots, leaves, and stems of tan and purple seed coat peanuts (Arachis hypogaea) cultivated in a growth chamber. Both cultivars showed higher levels of resveratrol in the roots than the other plant parts. Thus, both cultivars were inoculated with Agrobacterium rhizogenes, in vitro, to promote hairy root development, thereby producing enhanced levels of t-resveratrol. After 1 month of culture, hairy roots from the two cultivars showed higher levels of fresh weight than those of seedling roots. Furthermore, both cultivars contained higher t-resveratrol levels than those of their seedling roots (6.88 ± 0.21 mg/g and 28.07 ± 0.46 mg/g, respectively); however, purple seed coat peanut hairy roots contained higher t-resveratrol levels than those of tan seed coat peanut hairy roots, ranging from 70.16 to 166.76 mg/g and from 46.61 to 54.31 mg/g, respectively. The findings of this study indicate that peanut hairy roots could be a good source for t-resveratrol production due to their rapid growth, high biomass, and substantial amount of resveratrol.
