“…A necrotic reaction has been observed in in-vivo experiments by Lubberts and Toxopeus (1982). The necrosis of root tissue at the site of larval penetration may be ascribed to a hypersensitive reaction of root cells during or after penetration by larvae, similar to that described for BCN invasion in monosomic additions of Beta vulgaris X B. procumbens (Heijbroek et al, 1988) and for other host-parasite interactions involving Heterodera and Globodera species (Gommers, 1981). From the presented results it remains unclear if predominantly males or females in resistant S. alba had died as a consequence of necrosis, since it is difficult to assess the sex of larvae at an early J3 stage.…”

The development of Heterodera schachtii Schm. (beet cyst nematode, BCN) juveniles in roots of resistant and susceptible genotypes belonging to cruciferous crop species and hybrids was studied from 4 to 28 days after inoculation. No difference in root penetration by larvae was observed between resistant and susceptible plants.The development of nematodes in roots from resistant plants of Raphanus sativus L., resistant • Sageret and a resistant hybrid • • Brassica napus L. was similar. BCN resistance in these three sources of plant material appeared to be related to an increased male:female nematode ratio as compared to the ratio found in susceptible R. sativus plants.Also in resistant plants of Sinapis alba L. and a resistant intergeneric hybrid S. alba • B. napus the increase in male:female nematode ratio, as compared to the ratio found for susceptible S. alba cultivars and a susceptible intergeneric hybrid S. alba • B. napus, seemed to be related with the observed resistance. In roots of the resistant S. alba and of a resistant hybrid S. alba • B. napus, however, BCN resistance might also be due to a slower development of larvae and increased necrosis of root cells at the site of larval penetration.

“…BCN) is an important pathogen of sugar beet (Beta vulgaris L.). It can cause severe crop losses in the sugar beet growing areas of northwestern Europe (Heijbroek et al, 1988) and the USA (Steele and Savitsky, 1981). At present, resistant sugar beet varieties are not yet available.…”

“…Genes giving resistance or tolerance to the beet cyst nematode (Heterodera schachtii Schm.) have been found in wild beet species of the section Procumbentes, and intersection crosses with B. vulgaris established nematode-resistant lines including monosomic additions (2n= 19), fragment additions or diploid translocation [6,20,28,38,42,49]. A set of repetitive DNA sequences specific for the genome ofB.…”

Members of three prominent DNA families of Beta procumbens have been isolated as Sau3A repeats. Two families consisting of repeats of about 158 bp and 312 bp are organized as satellite DNAs (Sau3A satellites I and II), whereas the third family with a repeat length of 202 bp is interspersed throughout the genome. Multi-colour flourescence in situ hybridization was used for physical mapping of the DNA families, and has shown that these tandemly organized families occur in large heterochromatic and DAPI positive blocks. The Sau3A satellite I hybridized exclusively around or near the centromeres of 10, 11 or 12 chromosomes. The Sau3A satellite family I showed high intraspecific variability and high-resolution physical mapping was performed on pachytene chromosomes using differentially labelled repeats. The physical order of satellite subfamily arrays along a chromosome was visualized and provided evidence that large arrays of plant satellite repeats are not contiguous and consist of distinct subfamily domains. Re-hybridization of a heterologous rRNA probe to mitotic metaphase chromosomes revealed that the 18S-5.8S-25S rRNA genes are located at subterminal position on one chromosome pair missing repeat clusters of the Sau3A satellite family I. It is known that arrays of Sau3A satellite I repeats are tightly linked to a nematode (Heterodera schachtii) resistance gene and our results show that the gene might be located close to the centromere. Large arrays of the Sau3A satellite II were found in centromeric regions of 16 chromosomes and, in addition, a considerable interspersion of repeats over all chromosomes was observed. The family of interspersed 202 bp repeats is uniformly distributed over all chromosomes and largely excluded from the rRNA gene cluster but shows local amplification in some regions. Southern hybridization has shown that all three families are specific for genomes of the section Procumbentes of the genus Beta.
