A Preliminary Characterization and Assessment of Mesophotic Octocoral Microbiomes in the Western Gulf of Mexico

Mesophotic Coral Ecosystems are highly diverse and productive ecosystems in the western Gulf of Mexico which are composed of, in part, by octocorals (subclass Octocorallia). Despite their importance as foundational organisms octocorals are an understudied group in this region, with little known about their microbial community. Ninety-eight Octocoral samples collected from the western and northwestern Gulf of Mexico were sequenced using 16S rRNA sequencing to characterize their microbial communities. The sequenced microbiomes were generally low in diversity composed of a few core microbial taxa. Octocoral group was the main driver of microbiome composition as opposed to depth, season, region, and reef type. The effect of sequencing depth on a subset of 24 samples was examined, and showed low sequencing depth was sufficient to capture microbiome community trends. This microbiome data may be used to improve our understanding of the biology of octocorals in the Gulf of Mexico and contribute to conservation efforts in the future

The effect of photoperiod and temperature on yield in beans

Photoperiod insensitivity in the germplasm collection of beans (Phaseolus vulgaris) held at CIAT is found mostly in accessions from higher latitudes. Cold tolerance is found in accessions from the high Andes, but these are all photoperiod sensitive. A break in adaptation seems to occur at about 15 degrees C, between accessions specifically adapted to cool or warm temperatures. Those adapted to cool temperatures tend to have large seeds. An attempt is being made to combine adaptation to growing and yielding at low temperature with photoperiod insensitivity. A number of breeding lines have been selected which combine improved cold temperature tolerance with photoperiod insensitivity (e.g. VRA 81078, VRA 81072). The extent to which production regions of the world can be stratified according to the optimum photoperiod/temperature response required in bean cultivars is being studied in an international phenology nursery organized collaboratively by Cornell University and CIAT.

Photoperiod response in 1200 lines of beans tested at CIAT- Palmira 1982-3 : A listing

Results are given of a survey to determine the photoperiod response (18 vs. 12.3 h) of 1261 bean lines during 1982 and the 1st half of 1983 at CIAT-Palmira. (CIAT
