Tilly
Ed greeted me with a smile as soon as I walked into the lab's living quarters. Tall and thin, but otherwise unremarkable in appearance, he was my microbiologist and the closest thing we had to a plant pathologist. "Thanks for stopping by," he said. "Would you like some coffee?"
"Already had some," I replied, gesturing at the short tunnel that led back to the house. I spotted the dour-faced brunette behind Ed, sitting at the little table next to the kitchenette and nursing a steaming cup. I waved. "Good morning, Dawn."
"Oxymoron," the botanist grumbled.
"We pulled a late night," Ed explained with a shrug. None of us got more than, what, five hours?"
"Four," Dawn said, holding up that many fingers. The woman had always been confusing to me. Most of the time, she was cynical and fatalistic nearly to the point of parody, but every once in a while, a burst of positive emotion would break through. This was not one of those times.
"Stanley is still sleeping," Ed said with an apologetic shrug.
"Lucky bastard," Dawn muttered.
"Okay, so what's going on?" I asked. Knowing of my enhanced hearing, he had used the simple expedient of calling up the tunnel to summon me down here from the kitchen.
Ed was clearly excited and gesticulated as he spoke. "Well, last night we were analyzing one of our samples from the hybrid infection trials and--"
"Just show her," Dawn said, never taking her eyes from the black liquid in her cup.
"Yeah. Yes! I should show you," Ed said. "Uh, this way."
It could be difficult to tell age with most genemods after we reached maturity, but I had researched each candidate thoroughly before approving them for my team. Ed had been a prodigy, not uncommon with Eidetics, whose enhanced hippocampus enabled him to absorb information and recall it with near-perfect accuracy. Conventional education had been useless to him, so his parents had enrolled him in classes at UC Davis. He had toyed with pushing for a degree in medicine, but ultimately opted for a science track. He should be a few years older than me, but he acted more like a teenager sometimes.
Ed took me into the lab proper and over to a biosafety workstation. It was a sealed plexiglass box with thick gloves built into the near side for manipulating samples. It had a microscope built in as well.
Ed gestured at the microscope. "You should be able to see the spores in the test sample. We sent some stills out on the darknet for analysis, but Dawn said you should have a look at it in real time."
I bent to peer through the microscope. It took me only a second to spot what he wanted me to see. There was a piece of plant matter in the sample that covered most of my view. The blocky, semi-transparent cells were visible under the microscope's high magnification. Attached to the plant were a number of spheroid globs that had to be Rot spores.
"What's the plant?" I asked.
"Rosa chinensis and rubus allegheniensis."
"China rose and common blackberry," I mused, using their common names. The hybrid infection trials were our attempt to defeat Rot through plant hybridization, combining one species that was resistant to Rot with another species that was vulnerable and hoping the resulting plant showed resistance. It wasn't a simple proposition, since you generally needed closely-related species to form a hybrid, and chances were high that Rot attacked just about everything that was close enough in taxonomy to breed with the plant you wanted to protect. To create the cross-genus hybrids we needed, we couldn't use conventional methods of simply harvesting pollen from one plant to fertilize a second one. Dawn and Ed were using difficult and less reliable methods to create such hybrids, but our lab had the facilities needed to do it.
The Rosacea family of plants contains a whole host of flowering trees and shrubs, including several of the very fruits that grew in our orchard. About 90% of species in the family were resistant to Rot, but every known species of rose plant, genus Rosa, were susceptible to the oomycete. In roses, it resembled an oomycete disease called downy mildew.
I looked up from the microscope. "It doesn't look like the infection is taking hold. How long since the spores adhered?"
Ed shrugged. "We're coming up on twenty-four hours. We stayed up late to watch it, see if the infection would progress."
Rot spores that had found a compatible host plant first adhered to it, then penetrated the epidermis within twelve hours. I felt a prickle down my spine. Excitement yes, but I also felt uneasy about what we were seeing without knowing why. Maybe it felt too easy.
"This...this could be significant," I said cautiously, taking another glance through the microscope to assure that I wasn't missing something. "What's your next move?"
"Live plant trials," Dawn said, wandering in with her coffee clutched to her chest. "We have two hybrid plants." She waggled her hand towards a glass terrarium across the room with grow lights above it. The plants within were just a few inches tall but had sprouted several leaves each.
I sighed. "Alright, let's proceed, but carefully. When you run the test, use a fresh sample of Rot. I don't want to find out that we're dealing with some mutant strain that is less virulent. Is the hybrid sterile?"
"Most likely," Ed said with a nod. "I'd like to keep one plant and try breeding it to find out for sure. Getting two viable plants took a lot of time and effort."
"I agree," I said. "But make certain nothing leaves this lab until we're sure it's safe." That last part probably could have gone without saying. There was some danger in what we were trying, but Ed and Dawn knew their jobs.
"Great job, both of you," I added.
I felt Ed's flash of pride and pleasure at the compliment. A warm glow spread up my chest to match his wide smile. Dawn just nodded, and I felt nothing from her but her continued annoyance at being awake.
I took the opportunity to update them both on the status of the aquaponics farm. We had finished the skeletal structure of metal beams and supports and begun the laborious task of placing the polycarbonate panels that would make up the ceiling of the structure. We were still months away from completion, and more months still for our first harvest. Surprisingly, the hardest part of my plan seemed to be getting hold of live fish. I had Andy working on the problem, but I was starting to worry that we would get the structure completed and be unable to farm anything.
