Agrobacterium rhizogenes-Mediated Transformation of the Parasitic Plant Phtheirospermum japonicum
BACKGROUND Plants within the Orobanchaceae are an agriculturally important group of parasites that attack economically important crops to obtain water and nutrients from their hosts. Despite their agricultural importance, molecular mechanisms of the parasitism are poorly understood. METHODOLOGY/PRINCIPAL FINDINGS We developed transient and stable transformation systems for Phtheirospermum jap...
متن کاملA SUPERMAN-like gene is exclusively expressed in female flowers of the dioecious plant Silene latifolia.
To elucidate the mechanism(s) underlying dioecious flower development, the present study analyzed a SUPERMAN (SUP) homolog, SlSUP, which was identified in Silene latifolia. The sex of this plant is determined by heteromorphic X and Y sex chromosomes. It was revealed that SlSUP is a single-copy autosomal gene expressed exclusively in female flowers. Introduction of a genomic copy of SlSUP into t...
متن کاملA subtelomeric satellite DNA family isolated from the genome of the dioecious plant Silene latifolia.
In an ongoing effort to trace the evolution of the sex chromosomes of Silene latifolia, we have searched for the existence of repetitive sequences specific to these chromosomes in the genome of this species by direct isolation from low-melting agarose gels of satellite DNA bands generated by digestion with restriction enzymes. Five monomeric units belonging to a highly repetitive family isolate...
متن کاملPremature arrest of the male flower meristem precedes sexual dimorphism in the dioecious plant Silene latifolia.
Most dioecious plant species are believed to derive from hermaphrodite ancestors. The regulatory pathways that have been modified during evolution of the hermaphrodite ancestors and led to the emergence of dioecious species still remain unknown. Silene latifolia is a dioecious plant species harboring XY sex chromosomes. To identify the molecular mechanisms involved in female organ suppression i...
متن کاملEvidence for Degeneration of the Y Chromosome in the Dioecious Plant Silene latifolia
The human Y--probably because of its nonrecombining nature--has lost 97% of its genes since X and Y chromosomes started to diverge [1, 2]. There are clear signs of degeneration in the Drosophila miranda neoY chromosome (an autosome fused to the Y chromosome), with neoY genes showing faster protein evolution [3-6], accumulation of unpreferred codons [6], more insertions of transposable elements ...
