Analysis of expressed sequence tags in apomictic guineagrass (Panicum maximum)

The Present Status of C₄ Tropical Grasses Breeding and Molecular Approaches

“…Since apomixis also enables more rapid and efficient breeding, if a gene for apomixis were discovered, transgenic apomictic crops would hold considerable promise. Accordingly, many research groups, including our own, have worked to isolation of apomixis genes, both through molecular marker analysis (Ebina et al 2005) and through gene expression analysis in apomictic flowers (Yamada-Akiyama et al 2009). Guineagrass is one of the model plants for apomixis in tropical grasses.…”

Identification of Candidate Genes Related to Polyploidy and/or Apomixis in <i>Eragrostis curvula</i>

“…Sequences with similar annotations have been reported to be associated with apomixis and/or polyploidy for various other species, including Poa pratensis [53], Paspalum notatum [44,45], potato [54], Pennisetum squamulatum and Cenchrus ciliare [25], Panicum maximum [55], and Paspalum simplex [24,56]. Taking into account our previous results in E. curvula [32,33,35], the results of the present study, and those reported for other species by other authors, there are many commonalities among the different species with respect to apomixis.…”

Computational prediction and experimental verification of miRNAs in Panicum miliaceum L.

“…For example, miR159b-6 matched ESTs with three different gene members, miR444b-1 matched four, and miR528a-2 matched six (Table 2, Figure 2). One possible reason for this is that very few studies have been done on the Panicum genome [42] and some of the ESTs with distinct gene numbers (Table 2) may turn out to be identical when better assemblies of the genome become available. The apparent differences in the EST sequences may result either from mistakes, repeats in sequencing, or discrepancies between the different groups that generated the sequence [4347].…”
