Abstract Pierce’s disease is a deadly of grapevines caused by the bacterial pathogen Xylella fastidiosa (Xf). A resistance locus from Vitis arizonica/candicans b43-17 segregated as single dominant gene and mapped PdR1a PdR1b in two F1 sibling selections. The physical mapping allele allowed identification five ORFs Leucine-Rich Repeat Receptor Kinase family. Two ORFs: V.ari-RGA14 V.ari-RGA18 wer...

Abstract This is the first report evaluating genetic diversity of Mexican grape species utilizing DNA-based markers to understand distribution species, and patterns hybridization. The study utilized accessions maintained in three collections Mexico, one USA recently collected germplasm. Fifteen SSR were used develop a fingerprint database identify unique Two different clustering analyses withou...

The objective was to evaluate and compare the precision of estimation dasometric variables, survey times costs two sampling methods versus a census, applied natural even-age mass Pinus arizonica Engelm. in municipality Guachochi, Chihuahua, Mexico. Nine fixed-dimension nine variable-dimension sites were performed with Bitterlich's angular at coincident sample points. Times from start finish tak...

Servi kanserine sebep olan Seiridium cardinale (W.W. Wagener)’nin Çanakkale’de limoni servilerde (Cupressus macrocarpa cv. Goldcrest) yaygınlığı, hastalık oranı, morfolojik ve patojenik karakterizasyonun saptanması amacıyla 2021-2022 yılları arasında sörvey gerçekleştirilmiştir. Etmenin alanının tamamında var olduğu oranının % 1.65 saptanmıştır. Ana gövde veya yan dallarda geriye doğru ölüm, da...

Minimizing air, water, and soil pollution are very important for a sustainable environment. Particularly, ensuring the continuity of fertility without deteriorating structure is important. This objective can be achieved only by determining physical, biological, chemical properties atmospheric deposition taking required measures in agricultural lands. Trees plants reflect quality especially they...

In flammability assessment, the terpene effect is usually studied using their total or subgroup content, missing, therefore, information that could be provided by molecules themselves. this study, specific role of terpenes on leaf was sought comparing different levels identification—total, (i.e. mono-, sesqui-, and diterpene), single compound—as well as interactions with fuel moisture content (...

In previous years we have analyzed gene expression profiles of Pierce’s Disease (PD) resistant and susceptible genotypes of Vitis arizonica hybrids in response to infection by Xylella. fastidiosa (Xf), the bacterium causing PD. Here we report gene expression of the PD susceptible European grapevine, V. vinifera in response to Xf infection. RNA was extracted from healthy and infected leaf tissue...
