Aseptic isolation of leaf protoplasts from Citrus, Poncirus, Citrus × Poncirus hybrids and Severinia for use in somatic hybridization experiments

Scientia Horticulturae, 1987
Abstract An efficient protocol has been developed for the aseptic isolation of leaf protoplasts from Citrus and citrus relatives. Consistently high yields (2–6 × 10 7 protoplasts/g fresh weight tissue) of leaf protoplasts were isolated from new leaves taken from vigorously growing plants maintained in a growth chamber. Critical parameters included

Expression analysis of WRKY genes from Poncirus trifoliata in response to pathogen infection

, 2014
The majority of WRKY transcription factors (TFs) play a role in the regulation of defense response in plants. Three WRKY genes, PtrWRKY1, PtrWRKY2 and PtrWRKY3, were previously identified in Poncirus and their expressions were characterized in response ...

Rootstock impacts on citrus flush dynamics, vegetative growth, and Diaphorina citri infestation and dispersion: Implications for huanglongbing management

Pest Management Science, EarlyView.
Dwarfing citrus rootstocks restrict flush shoot growth on the scion, thereby reducing Asian citrus psyllid infestation, dispersal, and huanglongbing (HLB) progression. These findings support the use of dwarfing rootstocks as an effective cultural strategy in integrated HLB management for citrus orchards.

Genetic analysis of apomixis in Citrus and Poncirus by molecular markers

Theoretical and Applied Genetics, 1999
Propagation of citrus rootstocks depends upon the production of clonal plants from nucellar seedlings. This makes apomixis one of the host important traits in breeding programs for citrus rootstocks. The genetic control of apomixis was studied in a 50-tree progeny derived from the cross C. volkameriana×P.

A Systematic Map to Identify Knowledge Gaps on a Vector of Citrus Greening Diseases: The African Citrus Triozid, Trioza erytreae (Del Guercio, 1918) (Hemiptera: Triozidae)

Journal of Applied Entomology, EarlyView.
ABSTRACT Globally, citrus production areas are threatened by greening diseases, also known as Huánglóngbíng (HLB), associated with phloem‐limited gram‐negative species of the genus Candidatus Liberibacter. Those pathogens are transmitted by either the Asian citrus psyllid, Diaphorina citri Kuwayama 1908 (Hemiptera: Psyllidae), or the African citrus ...
