The Cucumber mosaic virus (CMV) Y-satellite RNA (Y-Sat) has a small non-protein-coding RNA genome that induces yellowing symptoms in infected Nicotiana tabacum (tobacco). How this RNA pathogen induces such symptoms has been a longstanding question. We show that the yellowing symptoms are a result of small interfering RNA (siRNA)-directed RNA silencing of the chlorophyll biosynthetic gene, CHLI....

A new huanglongbing (HLB) "Candidatus Liberibacter" species is genetically characterized, and the bacterium is designated "Candidatus Liberibacter psyllaurous." This bacterium infects the psyllid Bactericera cockerelli and its solanaceous host plants potato and tomato, potentially resulting in "psyllid yellowing." Host plant-dependent HLB transmission and variation in psyllid infection frequenc...

Cocos nucifera (CN), commonly known as Coconut tree, is used for its several beneficial health effects as antitumor, anthelmintic, antidotal, antiseptic, aperients, aphrodisiac, astringent, bactericidal, depurative, diuretic, hemostat, pediculicide, refrigerant, stomachic,styptic, suppurative and vermifuge. Our objective was to determine the antioxidant activities, DPPH radical scavenging activ...

Silique shattering resistance is one of the most important agricultural traits in oil crop breeding. Seed shedding from siliques prior to and during harvest causes devastating losses in oilseed yield. Lignin biosynthesis in the silique walls is thought to affect silique-shattering resistance in oil crops. Here, we identified and characterized B. napus LATE FLOWERING (BnLATE), which encodes a Cy...

But will there be anyone to remember us in another thousand years? Surely it's not possible that not a single molecule of memory will be found for us, like a yellowing manuscript at the bottom of a forgotten drawer, whose very cataloguing guarantees its eternity even if not a single reader ever discovers it. But will the catalog itself survive?

The maintenance of chlorophyll in darkened first leaves of oats was used as a bioassay for cytokinins in pea (Pisum sativum) roots. No cytokinin was found (in contrast with earlier reports on sunflower roots); however, the extracts contained two or more substances antagonistic to cytokinin, i. e., promoting the yellowing in this test. Because the most active of these appeared to be an amino aci...

Oil palm (Elaeis guineensis Jacq.) is one of the leading national commodities because its large contribution to Indonesian economy. In plantation industry, oil known as a commodity that has high value it an ingredient for producing oil. The genetic diversity accessions currently very low. effort increase diversity, germplasm exploration been carried out at center palm. addition exploration, oth...
