Plants often transmit information about their environments to their offspring through various epigenetic means, allowing their offspring to develop in ways that are likely to be adaptive to their local conditions. Our lab is interested in understanding these mechanisms and how/why they evolve in nature, and we are studying this problem of transgenerational plasticity in the cut-leafed monkeyflower, Mimulus laciniatus. Specifically, we are currently conducting several growth chamber and field experiments to perform genetic mapping and gene expression studies associated with this fascinating phenomenon, particularly as it relates to climate, and how it varies among natural populations. In learning about these mechanisms and their diversity, we hope to identify mechanisms that help populations adapt to predictably cycles in the environment and understand how they are fine-tuned to adapt populations to cope with different local environments.
The undergraduate researchers will grow, care for, and score phenotypes on monkeyflowers as part of our efforts to investigate the genetics of variation in how parent temperature affects offpsring traits. Depending on progress and success, they may also take part in RNA isolation and gene expression efforts. Depending on project needs and availability, the student may be involved in fieldwork as well. The student is invited to participate in weekly Blackman lab summer group meetings as well.
Students with strong interests in plant-environment interaction, genetics, evolution, and ecology will find the experience most rewarding. Attention to detail and good record keeping skills are essential. The student should be comfortable and enthusiastic about working in greenhouse and growth chamber conditions for extended periods, and they will be expected to follow guidelines for safely doing so. Students who are interested in working full time (wage or stipend support may be available) are especially encouraged to apply.
