Chrysanthemum stunt viroid (CSVd) was first reported in US in the 1940s and is widespread in the world wherever chrysanthemum is grown. Cryotherapy of shoot tips, a new biotechnology developed in the recent years, is a novel application of plant cryopreservation techniques that allows pathogen eradication at a high frequency. Existing studies have...

Chrysanthemum stunt viroid (CSVd) is a damaging pathogen attacking Argyranthemum plants. Our study attempted to reveal distribution patterns of CSVd in shoot apical meristems (SAM) and to explore reasons for differential ability of CSVd to invade SAM of selected Argyranthemum cultivars. Symptom development was also observed on greenhouse-grown Argy...

Potato (Solanum tuberosum L.) is globally the fourth largest staple crop after rice, wheat and maize. China is the largest potato producer worldwide, accounting for 26.3% and 22.2% of the global total area and yield, respectively. Viral diseases have been a limiting factor for sustainable production of potato in China. This article provides update...

Red raspberry, Rubus idaeus, is known to be infested by at least six species of eriophyid mites. Among them, the raspberry leaf and bud mite, Phyllocoptes gracilis, (Figure 1, A–B) is the only known vector of a raspberry virus, namely the raspberry leaf blotch virus (RLBV) (Dong et al. 2016; McGavin et al. 2012; Tan et al. 2022). Raspberry leaf blo...

The estimated global production of raspberry from year 2016 to 2020 averaged 846,515 tons. The most common cultivated Rubus spp. is European red raspberry (Rubus idaeus L. subsp. idaeus). Often cultivated for its high nutritional value, the red raspberry (Rubus idaeus) is susceptible to multiple viruses that lead to yield loss. These viruses are tr...

In May 2021, tomato (Solanum lycopersicum L.) plants with necrosis and ringspot symptoms were observed in a farm greenhouse at Sundbyfoss, Norway. This greenhouse production focused on ecological growing of several tomato varieties (i.e., “Blush Tiger”, “Sailor’s Luck”, “Evil Oliver”, etc.) with compost for local customers. The presence of tomato b...

Cryopreservation is considered an ideal strategy for the long-term preservation of plant genetic resources. Significant progress was achieved over the past several decades, resulting in the successful cryopreservation of the genetic resources of diverse plant species. Cryopreservation procedures often employ in vitro culture techniques and require...
Article
Plant virus eradication is a prerequisite in the use of virus‐free propagules for sustainable crop production. In contrast, virus preservation is also required in all types of applied and basic researches of viruses. Shoot tip cryopreservation can act as a double‐edged strategy, facilitating either virus eradication or virus preservation in cryo‐de...

Shallot (Allium cepa var. aggregatum), a small bulb onion, is widely grown in the world. We previously reported a droplet-vitrification for cryopreservation of in vitro-grown shoot tips of shallot genotype ‘10603’. The present study further evaluated rooting, vegetative growth, bulb production and contents of biochemical compounds, as well as genet...
Article
The present study described a combining thermotherapy with meristem culture for improved eradication of onion yellow dwarf virus (OYDV) and shallot latent virus (SLV) from co-infected in vitro-cultured shallot shoots. In vitro-cultured shoots infected with OYDV and SLV were thermo-treated at a constant temperature of 36 C for 0, 2 and 4 weeks, and...

The present study described a droplet-vitrification cryopreservation for shoot tips of shallot (Allium cepa var. aggregatum), a small bulb onion. Shoot tips taken from in vitro stock shoots were precultured with 0.3 M and 0.5 M of sucrose, with 1 day for each concentration. Precultured shoot tips were treated with a loading solution containing 2 M...

Potato (Solanum tuberosum L.) is one of the most important crops grown in Norway, and virus-free plants are required for commercial potato production and for preservation of potato germplasm. The present study evaluates three in vitro therapies – meristem culture, cryotherapy, and chemotherapy combined with thermotherapy – to eliminate viruses from...

Availability of and easy access to diverse plant viruses and viroids is a prerequisite in applied and basic studies related to viruses and viroids. Long-term preservation of viruses and viroids is difficult. A protocol was described for long-term preservation of potato leafroll virus (PLRV), potato virus S (PVS), and potato spindle tuber viroid (PS...

Virus diseases have been a great threat to production of economically important crops. In practice, the use of virus-free planting material is an effective strategy to control viral diseases. Cryotherapy, developed based on cryopreservation, is a novel plant biotechnology tool for virus eradication. Comparing to the traditional meristem culture for...

Viral diseases (a biotic stress) and salinity (an abiotic stress) have been/are the two major constraints for sustainable development of the world’s agricultural production including potato. Crops grown in field are often exposed simultaneously to abiotic and biotic stress, and responses of plants to co-stress by two or more factors may differ from...

Buds of in vitro-grown shoots of two purple-fleshed potato genotypes were successfully cryopreserved by encapsulation-vitrification (Encap-vitri) and droplet-vitrification (Drop-vitri). Optimal time durations of exposure to PVS2 for shoot regrowth of cryopreserved buds were 5–7 h and 6 h for ‘E03-2677’ and for ‘Blue Congo’, respectively, in Encap-v...

Viroids cannot be controlled by therapeutic treatments in fields, orchards, vineyards, or palm plantations. Hence, the elimination of viroids from infected plants has been a challenging issue and different approaches have been studied to produce viroid-free planting material. This chapter describes viroid elimination by thermotherapy, cold therapy,...

Chrysanthemum stunt viroid (CSVd) can infect Argyranthemum and cause serious economic loss. Low temperature treatment combined with meristem culture has been applied to eradicate viroids from their hosts, but without success in eliminating CSVd from diseased Argyranthemum. The objectives of this work were to investigate 1) the effect of low tempera...

Field performance evaluation and genetic integrity assessment were conducted in Argyranthemum plants derived from cryopreserved shoot tips. Some variations in root formation and vegetative growth were found in the plants following cryopreservation, but morphologies of the leaves and flowers, and color, number and size of the flowers remained unchan...

Effects of Potato leafroll virus (PLRV) and Potato virus Y (PVY) on vegetative growth, physiological metabolism and microtuber production were investigated using in vitro shoot cultures. The results showed that parameters of shoot growth including bud break percentage, shoot length, and node number and length were markedly reduced in the diseased s...

Horticultural crops are economically valuable for sustainable agricultural production. Plant diseases caused by Pathogens including virus, phytoplasma and bacterium have been a great threat to production of horticultural crops. The efficient use of pathogen-free plant materials has overcome the menace of plant diseases and has sustained crop produc...

The world population now is 6.7 billion and is predicted to reach 9 billion by 2050. Such a rapid growing population has tremendously increased the challenge for food security. Obviously, it is impossible for traditional agriculture to ensure the food security, while plant biotechnology offers considerable potential to realize this goal. Over the l...

Sweetpotato (Ipomoea batatas) ranks as the seventh most important staple crop in the world and the fifth in developing countries after rice, wheat, maize and cassava. Sweetpotato is mainly grown in developing countries, which account for more than 95% of total production of the whole world. Genetic resources, including cultivated varieties and wild...
