The major trimeric antenna complexes serve as a site for qH-energy dissipation in plants.

Plants and algae are faced with a conundrum: harvesting sufficient light to drive their metabolic needs while dissipating light in excess to prevent photodamage, a process known as nonphotochemical quenching. A slowly relaxing form of energy dissipation, termed qH, is critical for plants' survival under abiotic stress; however, qH location in the photosynthetic membrane is unresolved. Here, we tested whether we could isolate subcomplexes from plants in which qH was induced that would remain in an energy-dissipative state.

A Genetic Screen to Identify New Molecular Players Involved in Photoprotection qH in .

Photosynthesis is a biological process which converts light energy into chemical energy that is used in the Calvin-Benson cycle to produce organic compounds. An excess of light can induce damage to the photosynthetic machinery. Therefore, plants have evolved photoprotective mechanisms such as non-photochemical quenching (NPQ).

Insights Into Potato Spindle Tuber Viroid Quasi-Species From Infection to Disease.

Viroids are non-coding RNA plant pathogens that are characterized by their possession of a high mutation level. Although the sequence heterogeneity in viroid infected plants is well understood, shifts in viroid population dynamics due to mutations over the course of infection remain poorly understood. In this study, the ten most abundant sequence variants of potato spindle tuber viroid RG1 (PSTVd) expressed at different time intervals in PSTVd infected tomato plants were identified by high-throughput sequencing.

3' RNA ligase mediated rapid amplification of cDNA ends for validating viroid induced cleavage at the 3' extremity of the host mRNA.

5' RNA ligase-mediated rapid amplification of cDNA ends (5' RLM-RACE) is a widely-accepted method for the validation of direct cleavage of a target gene by a microRNA (miRNA) and viroid-derived small RNA (vd-sRNA). However, this method cannot be used if cleavage takes place in the 3' extremity of the target RNA, as this gives insufficient sequence length to design nested PCR primers for 5' RLM RACE. To overcome this hurdle, we have developed 3' RNA ligase-mediated rapid amplification of cDNA ends (3' RLM RACE).

The tomato I gene for Fusarium wilt resistance encodes an atypical leucine-rich repeat receptor-like protein whose function is nevertheless dependent on SOBIR1 and SERK3/BAK1.

We have identified the tomato I gene for resistance to the Fusarium wilt fungus Fusarium oxysporum f. sp. lycopersici (Fol) and show that it encodes a membrane-anchored leucine-rich repeat receptor-like protein (LRR-RLP).
