Insight Into

: Oilseed brassicas stand as the second most valuable source of vegetable oil and the third most traded one across the globe. However, the yield can be severely affected by infections caused by phytopathogens. White rust is a major oomycete disease of oilseed brassicas resulting in up to 60% yield loss globally. So far, success in the development of oomycete resistant Brassicas through conventional breeding has been limited. Hence, there is an imperative need to blend conventional and frontier biotechnological means to breed for improved crop protection and yield. : This review provides a deep insight into the white rust disease and explains the oomycete-plant molecular events with special reference to Albugo candida describing the role of effector molecules, A. candida secretome, and disease response mechanism along with nucleotide-binding leucine-rich repeat receptor (NLR) signaling. Based on these facts, we further discussed the recent progress and future scopes of genomic approaches to transfer white rust resistance in the susceptible varieties of oilseed brassicas, while elucidating the role of resistance and susceptibility genes. Novel genomic technologies have been widely used in crop sustainability by deploying resistance in the host. Enrichment of NLR repertoire, over-expression of R genes, silencing of avirulent and disease susceptibility genes through RNA interference and CRSPR-Cas are technologies which have been successfully applied against pathogen-resistance mechanism. The article provides new insight into Albugo and Brassica genomics which could be useful for producing high yielding and WR resistant oilseed cultivars across the globe.

White Rust

In rapeseed and mustard, the major diseases (downy mildew, white rust, Alternaria blight and Sclerotinia stem rot) cause 37–47%loss in pod formation and 17–54% reduction in grain yield. The identification of new sources of resistance is a high priority in breeding programs. About 3000 germplasm accessions of Indian mustard were evaluated under multiple environments (3 seasons) at hot spots (4 locations) and under artificial epiphytophic conditions against insect pests and diseases (aphids, white rust, powdery mildew and Alternaria blight). Accessions IC265495, IC313380, EC766091, EC766133, EC766134, EC766192, EC766230, EC766272 were identified as highly resistant to white rust (A. candida) with disease severity reaction (Percent disease severity Index, PDI = 0) under artificial inoculation. Accession RDV 29 showed the inheritance of resistant source for powdery mildew in Indian mustard. Screening of brassica wild relatives (about 25 species) for white rust found that Brassica fruticulosa, Brassica tournefortii, Camelina sativa, Diplotaxis assurgens, D. catholica, D. cretacia, D. Erucoides, D. Muralis, Lepidium sativum had highly resistance (PDI = 0) to Delhi isolates of white rust. Several traits identified from cultivated and related species will be useful for genetic improvement of rapeseed and mustard.

Functional Relations

Mustard (Brassica juncea L.) production in India suffers from aphid, Lipaphis erysimi (Kaltenbach), infestation considerably. Role of weather on the incidence and development of mustard aphids was assessed from experimental data from six north Indian locations. Aphid appearance and population build up was found to be regulated by temperature and time to attain peak population was relatively short in warm humid climates than in cool climates. Aphids appeared generally when the accumulated thermal time ranged between 810-847 and diurnal temperature range had a key role on the pest build up. Functional relations developed from the present study between aphid incidence and peak population using previous weeks weather and pest data for majority of the locations could be used for taking of any prophylactic/control measures. Projections on aphid population in future climates using generated weather variables indicated that warming may not increase aphid population at all locations uniformly.

Experiments conducted over 3 years have determined the potential of utilizing Indian mustard and `Tastie' head cabbage multi-species borders as trap crops for management of caterpillar pests of head cabbage in Hawaii. `Scorpio', a cultivar that showed less feeding damage than `Tastie', was used as the main crop. The studies point toward the use of isolated patches of multi-species attractant crops separated from the main crop by a buffer of non-host crops such as sweet corn. A sweet corn buffer was effective in preventing insect movement between plots. Initial studies showed the high susceptibility of Indian mustard to white rust (Albugo candida), to be a constraint to its use as a trap crop. Follow-up studies found that `Excel' and `Parkland' mustards may be adequate substitutes for mustard crop due to their attraction of caterpillars and their tolerance to white rust. Gradient experiments conducted on 60 × 30-m plots indicate that the trap crop may be effective for a distance of 25 to 30 m in terms of attraction of caterpillars and dispersal of beneficials into the main crop. A record was also made of growth, flowering patterns, and of beneficials hosted by 12 different Brassica cultivars during the winter and spring growing seasons.

Puccinia Horiana

Abstract A description is provided for Puccinia horiana. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Chrysanthemum indicum, C. japonense, C. makinoi, C. makinoi var. wakasaense, C. morifolium var. sinense, C. shiwagiku, C. shiwagiku var. kinokuniense and by inoculation on C. arcticum subsp. maekawanum, C. boreale, C. nipponicum, C. pacificum and C. yoshinaganthum (Hiratsuka, 1957). DISEASE: White rust disease of chrysanthemum. First noticed as yellow spots on the upper surface, the centres of the spots later turn brown. On the underside of the leaves, raised buff, pinkish, waxy pustules develop which later turn whitish and become quite prominent. Severe infection leads to complete loss of crop. GEOGRAPHICAL DISTRIBUTION: Africa (South Africa); Asia (China, Japan); Australasia (New Zealand); Europe (Austria, Belgium, Denmark, France, Great Britain, Finland, Germany, Netherlands, Norway, Sweden). (CMI Map 403, Ed. 2, 1966) TRANSMISSION: Sporidia disseminated by water splash account for the spread in individual plants. Importation of infected plants accounts for its rapid spread in new territories.
