The recognition of a positive correlation between organism genome size with its
transposable element (TE) content, represents a key discovery of the field of genome …

Transposable elements (TEs) are genomic units able to move within the genome of virtually
all organisms. Due to their natural repetitive numbers and their high structural diversity, the …

LTR retrotransposons are major components of plant genomes. They are regulated by a
diverse array of external stresses and tissue culture conditions, displaying finely tuned …

Long terminal repeat (LTR) retrotransposons are closely related to retroviruses, and their
activities shape eukaryotic genomes. Here, we present a complete Lotus japonicus insertion …

Use of insertion mutants facilitates functional analysis of genes, but it has been difficult to
identify a suitable mutagen and to establish large populations for reverse genetics in most …

Infection thread–dependent invasion of legume roots by rhizobia leads to internalization of
bacteria into the plant cells, which is one of the salient features of root nodule symbiosis. We …

We established a gene tagging population of the model legume Lotus japonicus using an
endogenous long terminal repeat (LTR) retrotransposon Lotus Retrotransposon 1 (LORE1) …

Genetic analyses of plant symbiotic mutants has led to the identification of key genes
involved in Rhizobium-legume communication as well as in development and function of …

A Tnt1-insertion mutant population of Medicago truncatula ecotype R108 was screened for
defects in nodulation and symbiotic nitrogen fixation. Primary screening of 9,300 mutant …

Several hundred genes are transcriptionally regulated during infection-thread formation and
development of nitrogen-fixing root nodules. We have characterized a set of Lotus japonicus …
