Deciphering molecular events behind Systemin-induced resistance to Botrytis cinerea in tomato plants.

Plant defence peptides are paramount endogenous danger signals secreted after a challenge, intensifying the plant immune response. The peptidic hormone Systemin (Sys) was shown to participate in resistance in several plant pathosystems, although the mechanisms behind Sys-induced resistance when exogenously applied remain elusive. We performed proteomic, metabolomic, and enzymatic studies to decipher the Sys-induced changes in tomato plants in either the absence or the presence of Botrytis cinerea infection.

Transcriptional and epigenetic changes during tomato yellow leaf curl virus infection in tomato.

Background: Geminiviruses are DNA plant viruses that cause highly damaging diseases affecting crops worldwide. During the infection, geminiviruses hijack cellular processes, suppress plant defenses, and cause a massive reprogramming of the infected cells leading to major changes in the whole plant homeostasis. The advances in sequencing technologies allow the simultaneous analysis of multiple aspects of viral infection at a large scale, generating new insights into the molecular mechanisms underlying plant-virus interactions.

Ultrasound-Guided Percutaneous Needle Electrolysis Combined With Therapeutic Exercise May Add Benefit in the Management of Soleus Injury in Female Soccer Players: A Pilot Study.

Context: The performance of sprints during male soccer matches usually is slow medium paced, where the soleus and gastrocnemius (ankle plantar flexors) play a very important role. As in male soccer, soleus injuries should be considered in female soccer; but the scientific evidence is very limited in this case.

Design: Pilot clinical trial study.

Begomovirus Tomato Leaf Curl New Delhi Virus Is Seedborne but Not Seed Transmitted in Melon.

Seed transmission can be of considerable relevance to the dissemination of plant viruses in nature and for their prevalence and perpetuation. Long-distance spread of isolates of the begomovirus species (genus , family ) has recently occurred from Asia to the Middle East and the Mediterranean Basin. Here, we investigated the possible transmission by melon ( L.

Cutting-edge technology to generate plant immunity against geminiviruses.

Geminiviruses (viruses with circular, single-stranded DNA genomes) are one of the major groups of plant viruses causing severe economic problems for agriculture worldwide. The control of these pathogens has become a priority to maintain the production of important crops, including cotton, maize, cassava, and other vegetables. Obtaining resistant plants is the most powerful strategy and a key factor to stablish an effective integrated pest management for a robust control.

Characterization of Curtovirus V2 Protein, a Functional Homolog of Begomovirus V2.

Geminiviruses are single-stranded DNA plant viruses with circular genomes packaged within geminate particles. Among the family, and comprise the two best characterized genera. Curtovirus and Old World begomovirus possess similar genome structures with six to seven open-reading frames (ORF).

Revisiting Seed Transmission of the Type Strain of in Tomato Plants.

Isolates of the (TYLCV) species (genus , family ) infect tomato crops worldwide, causing severe economic damage. Members of the whitefly sibling species group are the vector of begomoviruses, including TYLCV. However, transmission of isolates of the type strain (Israel [IL]) of TYLCV (TYLCV-IL) by tomato seed has recently been reported based on infections occurring in Korea.
