Organisation, sequence diversity and evolution of a disease-resistance gene cluster in coffee tree (Coffea l.) [PDF]

open access: yes, 2008
Pathogen resistance (R) genes of the NBS-LRR class (for nucleotide binding site and leucine-rich repeat) are found in all plant species and confer resistance to a diverse spectrum of pathogens.

Growth, production, and bean quality of Coffea arabica as affected by interspecific grafting : Consequences for rootstock breeding [PDF]

open access: yes, 2001
In order to avoid nematode damage to roots of Coffea arabica L. in Latin America, a common practice is interspecific grafting on C. canephora var. Robusta (Pierre) rootstocks. The performance of two C.

Genetic Diversity and Population Structure Analysis of Coffee (Coffea canephora) Germplasm Collections in Indian Gene Bank Employing SRAP and SCoT Markers

open access: yes, 2020
Coffea canephora Pierre ex Frohener is popularly known as robusta coffee contributes to about 39% of the total world coffee production. Coffea canephora a native to West Africa was introduced to India as early as 1900 AD.

Commodity risk assessment of Petunia spp. and Calibrachoa spp. unrooted cuttings from Uganda

open access: yesEFSA Journal, Volume 24, Issue 1, January 2026.
Abstract The European Commission requested the EFSA Panel on Plant Health to evaluate the likelihood of pest freedom at entry in the EU, including both regulated and non‐regulated pests, potentially associated with unrooted cuttings of the genera Petunia and Calibrachoa produced under physical isolation in Uganda.

Physiological and molecular responses of diploid and tetraploid Carrizo Citrange under water Stress : S02P14 [PDF]

open access: yes, 2013
In citrus, the use rootstock promotes productivity, improves fruit quality and may confer resistance or tolerance to biotic and abiotic stress. 'Carrizo' citrange (Citrus sinensis [L.] Osbeck × Poncirus trifoliata [L.] Raf), is one of the most popular ...

Early Selection Enabled by the Implementation of Genomic Selection in Coffea arabica Breeding

open access: yesFrontiers in Plant Science, 2019
Genomic Selection (GS) has allowed the maximization of genetic gains per unit time in several annual and perennial plant species. However, no GS studies have addressed Coffea arabica, the most economically important species of the genus Coffea. Therefore,
