ANATOMICAL STRUCTURE OF THE PERENNIAL STEM IN DIFFERENT ROSA L. SPECIES [PDF]

Journal of Plant Development
The observations comprise a comparative study of the anatomical structure of the perennial stem in the species Rosa canina L., R. damascena Mill., R. rubiginosa L., and R. rugosa Thunb., cultivated in the Botanical Garden of Iasi. Cambial activity gives

Combined application of Bacillus velezensis JDB15 and Trichoderma harzianum JDL4 suppresses banana Fusarium wilt under controlled conditions

Pest Management Science, EarlyView.
The surfactin C secreted by JDB15 and the probable parasitism of JDL4 lead to the leakage of intracellular macromolecules and the degradation of hyphae, respectively. Combined application of the two strains effectively controls banana Fusarium wilt under controlled conditions.

‘Paedomorphosis’ and ‘juvenility’ in secondary xylem: (not such) useful constructs?

IAWA Journal, 2023
Summary In 1962 Carlquist published “A Theory of Paedomorphosis in Dicotyledonous Woods” based on his observations that some species of non-tree growth forms such as stem succulents, lianas, woody herbs, and tree rosettes exhibit, in their secondary xylem, cellular characteristics more commonly associated with primary xylem.

Host‐induced silencing of the Minc09294 effector gene impairs Meloidogyne incognita and M. Enterolobii infection

Pest Management Science, EarlyView.
Host‐induced gene silencing of the effector candidate Minc09294 significantly impairs Meloidogyne incognita parasitism, markedly reducing gall formation, reproduction, and the development of specialized giant cells, with partial cross‐species effects on M.

Proteomic analysis during ontogenesis of secondary xylem in maritime pine [PDF]

Tree Physiology, 2014
Secondary xylem (wood) is formed through an intricate biological process that results in a highly variable final product. Studies have focused on understanding the molecular events for wood formation in conifers. In this process environmental, ontogenic and genetic factors influence variation in wood characteristics, including anatomical, chemical and ...

Chlorantraniliprole: bioactivation in coffee seedlings and control of resistant Leucoptera coffeella populations

Pest Management Science, EarlyView.
Chlorantraniliprole enhanced growth and biomass in coffee seedlings infested by susceptible Leucoptera coffeella, while resistant populations limited its insecticidal performance. These findings emphasize both the bioactivator potential of chlorantraniliprole and the challenges of managing resistance in coffee leaf miner control.

LsFAMeT and LsJHAMT coordinate JH biosynthesis to regulate fecundity in Laodelphax striatellus

Insect Science, EarlyView.
The small brown planthopper (SBPH), Laodelphax striatellus, can trigger large‐scale outbreaks when encountering suitable habitats during migration due to their strong reproductive ability. This study investigated the role of juvenile hormone (JH) in regulating SBPH reproduction.

A defensive symbiont and a plant virus confer direct and discrete phenotypes to a cereal aphid in a context‐dependent manner

Ecological Entomology, EarlyView.
Different BYDV‐PAV isolates exert contrasting effects on aphid fitness, including reproduction and winged production. Different BYDV‐PAV isolates have contrasting effects on aphid dispersal patterns. Aphid feeding behaviour is modulated by the presence of endosymbionts and plant viruses.
