Resistance to Rhopalosiphum padi (Homoptera: Aphididae) in three triticale accessions.
Experiments were conducted to identify and characterize host plant resistance to bird cherry-oat aphid, Rhopalosiphum padi (L.), in various wheat and wheat-grass hybrids. Initial tests screened for resistance to R. padi among 12 grass accessions (eight wheat [Triticum aestivum L.], three triticale [XTriticosecale Wittmack], and 1XElytricum [Elytrigia elongata [Host] Nevski x Triticum aestivum h...
متن کاملSequence requirements for translation initiation of Rhopalosiphum padi virus ORF2.
Rhopalosiphum padi virus (RhPV) is an aphid-infecting virus with a 10-kb ssRNA genome that contains two large open reading frames (ORFs). ORF1 and ORF2 encode the nonstructural and structural polyproteins, respectively. Both ORFs are preceded by noncoding regions of 500 nt that could function as internal ribosome entry segments (IRESes). The sequence for ORF2 lacks an obvious initiation codon, ...
متن کاملResponses of holocyclic and anholocyclic Rhopalosiphum padi populations to low‐temperature and short‐photoperiod induction
The different life cycles of aphid species make these organisms good models for studying the short-term consequences of sex. The bird cherry-oat aphid Rhopalosiphum padi has a wide geographic distribution and correspondingly different life cycles. In this study, the life cycles of R. padi collected from six different regions in China were characterized experimentally by comparing the responses ...
متن کاملTPS46, a Rice Terpene Synthase Conferring Natural Resistance to Bird Cherry-Oat Aphid, Rhopalosiphum padi (Linnaeus)
Plant terpene synthases (TPSs) are key enzymes responsible for terpene biosynthesis, and can play important roles in defense against herbivore attack. In rice, the protein sequence of TPS46 was most closely related to maize TPS10. However, unlike maize tps10, tps46 was also constitutively expressed in rice even in the absence of herbivore attack. Potential roles or constitutive emissions of spe...
متن کاملRhopalosiphum padi (Hemiptera: Aphididae) responses to volatile cues from Barley yellow dwarf virus-infected wheat.
In choice bioassays, Rhopalosiphum padi L. nonviruliferous apterae preferentially locate near volatile organic compounds (VOCs) emitted from Barley yellow dwarf virus (BYDV)-infected wheat plants compared with VOCs from noninfected plants. However, the specific VOCs responsible for R. padi responses are unknown. It is unclear also if R. padi responses to BYDV-infected wheat are caused by arrest...
