Pest Management Science, EarlyView.This review bridges the gap between understanding resistance mechanisms and applying them in weed management, highlighting how mechanistic insights reveal vulnerabilities that can guide more effective control strategies. Abstract Herbicide resistance remains one of the most intensively studied areas in weed science because of its direct consequences ...

Messenger RNas : their utilization and degradation during pollen germination and tube growth
Acta Societatis Botanicorum Poloniae, 2014 During pollen germination and tube growth at least 230 new proteins are synthesized, as determined by 35S-methionime labeling and two dimensional gel electrophoretic analysis of the labeled proteins.

Pest Management Science, EarlyView.Using cellular phenotyping and resistance profiling, we show that herbicides across the Herbicide Resistance Action Committee (HRAC) Groups 3 and 23 induce indistinguishable, dose‐dependent microtubule defects. Resistance patterns, rather than cellular phenotypes, reveal distinct sites of action and support reclassifying Group 3 as α‐tubulin binders ...

Molecular Mechanisms of Pollen Tube Growth and Differentiation [PDF]
The Plant Cell, 1993 ' The extremely reduced, three-celled, haploid male plant (male gametophyte) of flowering plants has a number of specialized functions to perform. The primary functions are the production of two sperm cells and their transport within the pollen tube through the tissues of the style and ovary into the embryo sac in the ovule, where they participate in ...

Pest Management Science, EarlyView.Presence and abundance of Botryosphaeria dieback inoculum were determined using spore trapping and droplet digital polymerase chain reaction in British Columbia, Canada. Highest inoculum was recorded in spring (April–June) and again in summer (July–September). These results suggest early pruning in December–January can mitigate pruning wound infections.

Acta Agrobotanica, 2015 During four years (1971-1974), five sour cherry cultivars were examined for the pollen viability, germination and pollen tube growth. Pollen which was taken from the earliest and the last blooming stages had the smaller viability, germination and the ...

Pest Management Science, EarlyView.Field‐collected Ambrosia artemisiifolia populations from Michigan, USA, soybean fields exhibited strong resistance to the protoporphyrinogen IX oxidase (PPO)‐inhibiting herbicide sulfentrazone and reduced sensitivity to fomesafen. Target‐site analysis identified a novel Arg‐98‐Gln (R98Q) substitution in PPO2, co‐occurring with the previously reported ...

EFFECT OF DIFFERENT FACTORS ON GERMINATION AND TUBE GROWTH OF Solanum sisymbrifolium LAM. POLLEN
Annals of Tropical Research, 1988 Both germination and tube growth of Solanum sisymbrifolium Lam. pollen require an optimum temperature of 25°C and a growth medium containing 100 ppm boric acid, 10% sucrose and 0.6% Bacto-agar. Pollen germination was stimulated by 5 and 10 ppm GA3, 1-10

Pest Management Science, EarlyView.Resistance to Cry2Ab2 protein in Ostrinia nubilalis is autosomal, functionally recessive, controlled by a single gene, and remains stable over 17 generations in the absence of Cry2Ab2 selection pressure. Abstract BACKGROUND Transgenic corn expressing insecticidal proteins from the bacterium Bacillus thuringiensis (Bt), including Cry1Ab, Cry1Fa and/or ...
