Menurunnya tingkat produksi kopi robusta dalam negeri dipengaruhi karena banyak faktor, salah satunya adalah menurunnya sumbangsih hasil dari kelompok tani yang juga menunjang nasional. Penelitian bertujuan untuk mengetahui prioritas upaya peningkatan kinerja sektor hulu budidaya pada petani robusta. Metode penelitian digunakan SWOT dan AHP dengan pengambilan data lokasi di Kelompok Tani Kopi R...

BACKGROUND AND AIMS Dehydrins, or group 2 late embryogenic abundant proteins (LEA), are hydrophilic Gly-rich proteins that are induced in vegetative tissues in response to dehydration, elevated salt, and low temperature, in addition to being expressed during the late stages of seed maturation. With the aim of characterizing and studying genes involved in osmotic stress tolerance in coffee, seve...

Four new species of the huntsman spider genus Pseudopoda Jäger, 2000 are described from Southern China: Pseudopoda acuminata sp. n. from Suiyang County, Guizhou Province, P. emei sp. n. from Emei Mountain, Sichuan Province, P. lacrimosa sp. n. from Fugong County and Tengchong County, Yunnan Province, and P. robusta sp. n. fromJinyun Mountain, Chongqing Municipality.

We report draft genome sequences of three Mexican Erwinia amylovora strains. A novel plasmid, pEA78, was identified. Comparative genomics revealed an rpsL chromosomal mutation conferring high-level streptomycin resistance in two strains. In the effector gene avrRpt2, a single nucleotide polymorphism was detected that overcomes fire blight disease resistance in Malus × robusta 5.

Accurate identification of cyanobacteria using traditional morphological taxonomy is challenging due to the magnitude of phenotypic plasticity among natural algal assemblages. In this study, molecular approach was utilized to facilitate the accurate identification of cyanobacteria in the Sacramento-San Joaquin Delta and in Clear Lake in Northern California where recurring blooms have been obser...

Of the two commercially cultivated coffee (Coffea) species, C. arabica (arabica) is highly susceptible and C. canephora (robusta) is highly resistant to the insect pest Xylotrechus quadripes (Coleoptera: Cerambycidae), commonly known as coffee white stem borer (CWSB). We constructed a forward-subtracted cDNA library by Suppression Subtractive Hybridization (SSH) from robusta bark tissue for pro...
