ABSTRACT Jasmonate (JA) regulates defence responses in plants. However, JA‐induced defence often results in growth inhibition. This process is largely mediated by MYC2, the master regulator of JA signalling. Nevertheless, the underlying molecular mechanisms have not yet been fully uncovered.

ABSTRACT Global food demand is predicted to rise anywhere from 59% to 98% by 2050 because of increasing population. However, the continued depletion of natural resources and increasing biotic and abiotic stresses will continue to pose significant threats to global food security in coming years.

Studies on the Diapause in the Planthoppers
1) ヒメトビウンカ幼虫を初令から20∼22°Cで種々な日長の下に飼育した。2) 日長が8∼10時間では休眠率は100%になるが,日長がこの範囲からはずれると休眠率は減少する。12時間では約35%の非休眠個体を生じ,14時間ではすでに100%非休眠となる。全期間暗黒状態では約18%の休眠率となる(第1図,第2図)。3) 休眠した個体は4令期間が延びるが,同じ条件下でも徐々ながら発育し,4令期間の個体変異は非常に大きい。休眠個体と非休眠個体との区別は,少なくとも発育日数からは明白にはつけにくい。4) 休眠に入った幼虫も日周期に対する感受性をもっており,長日や極端な短日下では急速に発育を始め,かなり斉一な羽化が見られる。最も長い休眠状態は休眠誘起に好適な日長下で維持される ...

A reovirus in the brown planthopper, Nilaparvata lugens
A new virus, belonging to the reovirus group, was found in an apparently healthy colony of the brown planthopper, Nilaparvata lugens, and was referred to as the Nilaparvata lugens reovirus (NLRV). The virus was found in the cytoplasm of the insect cells, sometimes associated with tubular structures, which is one of the characteristic features in ...

Abstract Rice (Oryza sativa L.) production remains central to global food security, particularly across Asia, where both wetland and upland cultivation systems dominate. These agroecosystems face distinct ecological and agronomic constraints that threaten sustainable intensification.

A Cripavirus in the brown planthopper, Nilaparvata lugens
A Cripavirus-like long unique sequence was identified during transcriptome sequencing of the brown planthopper (BPH), Nilaparvata lugens. This unique sequence demonstrated high similarity with the whole-genome sequence of cricket paralysis virus, including 5' and 3' untranslated regions; thus we considered it the whole genome of a new virus. We propose

Sexual dimorphism and stress‐induced stridulatory responses in Jaguajir rochae (Borelli, 1910). Females exhibited greater absolute pectinal size and higher sound pressure levels, whereas males showed higher pectinal allometric ratios relative to body size, lower sound frequencies, and shorter delta times.

ABSTRACT Within the subfamily Heliothinae, the genus Helicoverpa comprises several highly destructive agricultural pests, including H. armigera, H. assulta, H. punctigera and H. zea. These species cause significant global crop losses due to their wide host range, long‐distance migratory behaviour, and potential for interspecific hybridization.

Why cave planthoppers study matters: are Cixiidae a subtroglophile lineage? (Hemiptera, Fulgoromorpha) [PDF]
Planthoppers are an interesting and contrasting model among insects for studying the subterranean environments. Their morphological and ethological adaptations to the underground conditions (complete darkness, lower temperatures, high hygrometry ...

This review focuses on mitogen‐activated protein kinase (MAPK) activation and summarizes how plants regulate and integrate MAPK signaling in modulating plant immune responses. It also examines the effectors pathogens have evolved to manipulate MAPK activation and thereby inhibit plant immunity.
