Many plant tissues, including phloem and xylem from loblolly pine (Pinus taeda L.), contain high levels of phenolics and polysaccharides that interfere with RNA purification. This presentation discusses techniques for the harvest of field-grown tissues and isolation of RNA of sufficient quality for microarrays and other genomic analyses.

We present a non-lethal and automated mechanism to collect pollen from bumble bee (Bombus) workers returning to a hive. Instructions for producing, preparing, installing and using the devices are included. By using 3D-printed objects, modification to the design was timely, efficient and allowed for quick turnaround for testing.
FAQs
During formation in the pollen sacs, meiosis produces genetically distinct grains rather than identical copies. This variation gives conifer pollen a connection to population genetics and evolution because pollen records the reproductive contribution of male plants. In research, that makes pollen relevant not only to fertilization but also to examining diversity within conifer groups.
In many conifers, air-filled sacs help wind disperse pollen toward female cones. This feature links grain structure with the plant’s pollination strategy: pollen must remain available for movement through the air and reach the reproductive structures of female cones. Studying this relationship helps biologists connect physical grain traits with successful sexual reproduction in wind-pollinated conifers.
Distinctive pollen shapes and wall structures provide more than identification features. Because these characteristics can be preserved, researchers can recognize conifer pollen in materials studied after deposition and compare the biological evidence across samples. That persistence supports investigations of plant diversity and environmental change, including work in paleobotany and sediment analysis.
Researchers can examine the distinctive shapes and wall structures of conifer pollen preserved in sediment. They use those characteristics as evidence of the plant diversity represented in a sample. In sediment analysis, this approach connects biological remains with past or changing vegetation, making pollen useful for paleobotanical investigations and studies of environmental change.
Conifer pollen is useful across several fields because its preserved traits connect reproductive biology with environmental evidence. Paleobotany uses it to investigate plant history, while sediment analysis can examine pollen contained in deposited material. Environmental monitoring applies pollen evidence to study environmental change, extending its value beyond studies of individual conifer reproduction.
Seasonal airborne allergen investigations treat conifer pollen as biological material whose presence can be monitored in the air over time. Its relevance comes from wind dispersal and its occurrence in seasonal airborne contexts, while distinctive structures help identify the material being examined. This connects plant reproductive timing with environmental monitoring and studies of airborne allergens.
