Abstract: Root-knot nematodes (RKN) are pathogens affecting soybean production worldwide. Rmi1 (Resistance to M. incognita 1) is an additive gene for M. incognita resistance identified in soybean cv. Forrest, which resides in a major QTL on Chromosome 10. It has been established that Rmi1 is associated with multiple polymorphisms in the promoter and sequences of genes encoding ?-1,4-endoglucancase (EG) and pectin methylesterase (PME1), both of which exhibit higher expression in susceptible than in Rmi1 resistant plants. EG expression is correlated with RKN feeding cell formation, indicating EG functions as a susceptibility factor for soybean resistance to M. incognita. Plants, including genetically modified and transgenic plants, cells and seeds thereof that lack expression or functional gene products of EG and/or PME1 are provided. Compositions and methods for reducing or removing EG and/or PME1 expression in plants are also described.

Abstract: Herein provided is a new soybean variety designated ‘G13LL-44’ as well as the seeds, plants and derivatives of the new soybean variety ‘G13LL-44’. Also provided are tissue cultures of the new soybean variety ‘G13LL-44’ and the plants regenerated therefrom. Methods for producing soybean plants by crossing the new soybean variety ‘G13LL-44’ with itself or another soybean variety and plants produced by such methods are also provided. ‘G13LL-44’ is a MG VII line with glufosinate tolerance technology, and with resistance to race 3 of the soybean cyst nematode and frogeye leaf spot, and moderate resistance to southern root-knot nematode. ‘G13LL-44’ yielded 1.4 bu/ac (2.3%) greater than its recurrent parent ‘G00-3213’, across 11 environments and 0.5 bu/ac more than the high-yielding check cultivar ‘AG738 RR’. ‘G13LL-44’ provides a high yielding glufosinate tolerant soybean cultivar with superior nematode resistance.

Abstract: Markers tightly associated with a sorghum (Sorghum bicolor) cms fertility restorer gene are identified, as well as genes containing the pentatrico peptide repeat (PPR) motif. Methods for marker assisted selection of restorer and non-restorer sorghum lines are provided. The markers can be used to facilitate development of the maintainer, restorer and cms sorghum lines used to make hybrids.
