Dehulled seeds of rice (Oryza sativa L.) cultivar Nipponbare were sterilized with 75% ethanol for 1 min. These seeds were further sterilized with 2.5% sodium hypochlorite for 20 min, washed at least five times with sterile water and then incubated on 1/2 MS medium with a photoperiod of 12 h light (about 150 μmol m-2 s-1) and 12 h dark at 26°C for 7-10 days. Green tissues from the stem and sheath of 40-60 rice seedlings were used. A bundle of rice plants (about 30 seedlings) were cut together into approximately 0.5 mm strips with propulsive force using sharp razors. The strips were immediately transferred into 0.6 M mannitol for 10 min in the dark. After discarding the mannitol, the strips were incubated in an enzyme solution (1.5% Cellulase RS, 0.75% Macerozyme R-10, 0.6 M mannitol, 10 mM MES at pH 5.7, 10 mM CaCl2 and 0.1% BSA) for 4-5 h in the dark with gentle shaking (60-80 rpm). After the enzymatic digestion, an equal volume of W5 solution (154 mM NaCl, 125 mM CaCl2, 5 mM KCl and 2 mM MES at pH 5.7) was added, followed by vigorous shaking by hand for 10 sec. Protoplasts were released by filtering through 40 μm nylon meshes into round bottom tubes with 3-5 washes of the strips using W5 solution. The pellets were collected by centrifugation at 1,500 rpm for 3 min with a swinging bucket. After washing once with W5 solution, the pellets were then resuspended in MMG solution (0.4 M mannitol, 15 mM MgCl2 and 4 mM MES at pH 5.7) at a concentration of 2 × 106 cells mL-1, determined by using a hematocytometer. The viability of protoplasts was determined by the FDA staining method as described [44 (link)]. All manipulations above were performed at room temperature.
For isolating protoplasts from etiolated rice seedlings, the sterilized seeds were germinated under light for 3 days, and then moved to the dark for another 4-7 days. The isolation procedure was the same as that for isolation of green tissue protoplasts described above.

DNA was extracted from ∼100 mg of bone power after sodium hypochlorite treatment (SI Appendix 2). Sequencing, filtering of the data, and genotyping was carried out as previously described (ref. 3 (link) and SI Appendix 3). Present-day human DNA contamination was estimated using mitochondrial, autosomal data, and from the proportion of DNA fragment mapping on the Y chromosome (SI Appendixes 4 and 5). Demographic histories and split times were estimated using the Pairwise Sequentially Markovian Coalescent (38 (link) and SI Appendix 6) and the F(A|B) method (refs. 35 (link) and SI Appendix 7), respectively, and coestimated with momi2 (39 and SI Appendix 7). HBD tracts were computed as previously published (refs. 35 (link) and SI Appendix 8). Selection analyses were performed using the R packages GOfuncR (https://github.com/sgrote/GOfuncR), ABAEnrichment (ref. 29 (link) and SI Appendix 9), and by computing HKA and a modified PBS statistic in 25-kb windows (SI Appendix 10).

Flowering plants were grown essentially as described [1 (link)]. Selection of transgenic seeds on agar was on solid MS3 media [4.4 g/L Murashige & Skoog Basal Salt mixture (Sigma-Aldrich cat: M5524), 30 g/L sucrose, 0.5 g/L Monohydrate 2-(N-morpholino)ethanesufonic acid (MES); adjusted pH 5.7, 1.5% phyto agar (Duchefa Biochemie)]. Seed sterilization was as described [1 (link)], except that a 33% commercial bleach/Triton X-100 solution was used [33% DanKlorix (this is ~28 g/L sodium hypochlorite; Colgate-Palmolive; Hamburg) and 200 μL/L Triton X-100].
Selection on sand in a plastic-petri plate started with saturating chromatography sand with liquid MS0 media (1.1 g/L MS basal salt, 0.5 g/L MES; adjusted pH 5.7). The sands reported here were i) Silicon dioxide (SiO2); purum p.a.; acid purified; 40–200 mesh (84880 – Fluka), and ii) Quartz (SiO2); purum p.a.; powder; < 230 mesh (00653 – Sigma). Appropriate antibiotics were added to the MS0 solution before sand saturation. Dry seeds were sprinkled onto the wet sand, and after a two-day treatment at 4°C, plants were allowed to grow for two weeks.

D. melanogaster lines with Wolbachia are described in Table 1. Lines with Wolbachia variants described in Riegler et al.[40] (link) were kindly provided by Markus Riegler and Scott O'Neill. wMelCS_b source and DrosDel w1118 isogenic background were described elsewhere [12] , [59] (link). wMel variants were introduced in the DrosDel w1118 iso isogenic background by chromosomes replacement using a first and third double balancer line and a second chromosome balancer line. The crosses were performed with Wolbachia-infected females, ensuring endosymbiont transmission through the germline. The fourth chromosome was not isogenized. All the Wolbachia genotypes were confirmed by PCR, as described in Riegler et al.[40] (link) (data not shown).
The lines were cleaned of possible chronic viral infections as described elsewhere [12] , [60] .
In order to homogenize the gut microbiota, embryos from each line were sterilized with 2% sodium hypochlorite, followed by 70% ethanol and washed with sterile water. Embryos were placed in new food vials and 150 µl of a bacterial inoculum from a reference stock was added. The inoculum was produced by mixing 5 ml of sterile water with 2 g of food from 10 days old vials containing VF-0058–3 flies [12] , and filtering it to remove eggs and larvae.
Tetracycline-treated lines were cleaned of Wolbachia infection by raising them for two generations in ready-mix dried food (Philip Harris) with 0.05 mg/ml of tetracycline hydrochloride (Sigma). Experiments were performed on lines that were raised without antibiotics for at least 6 generations.
Drosophila lines were maintained on standard cornmeal diet at a constant temperature of 25°C. We focused the analysis on males in the assumption that Wolbachia levels would be more stable in these. Wolbachia is present in ovaries and the sizes of these vary greatly with mating status and physiology of the female.

Plant transformation—The Arabidopsis thaliana var Columbia (To plants) were transformed according to the Floral Dip procedure [Clough S J, Bent A F. (1998) Floral dip: a simplified method for Agrobacterium-mediated transformation of Arabidopsis thaliana. Plant J. 16(6): 735-43; and Desfeux C, Clough S J, Bent A F. (2000) Female reproductive tissues were the primary targets of Agrobacterium-mediated transformation by the Arabidopsis floral-dip method. Plant Physiol. 123(3): 895-904] with minor modifications. Briefly, Arabidopsis thaliana Columbia (C010) T0 plants were sown in 250 ml pots filled with wet peat-based growth mix. The pots were covered with aluminum foil and a plastic dome, kept at 4° C. for 3-4 days, then uncovered and incubated in a growth chamber at 18-24° C. under 16/8 hours light/dark cycles. The T0 plants were ready for transformation six days before anthesis.

Single colonies of Agrobacterium carrying the binary vectors harboring the genes of some embodiments of the invention were cultured in YEBS medium (Yeast extract 1 gr/L, Beef extract 5 gr/L, MgSO4*7H2O, Bacto peptone 5 gr/L) supplemented with kanamycin (50 mg/L) and gentamycin (50 mg/L). The cultures were incubated at 28° C. for 48 hours under vigorous shaking to desired optical density at 600 nm of 0.85 to 1.1. Before transformation into plants, 60 μl of Silwet L-77 was added into 300 ml of the Agrobacterium suspension.

Transformation of T0 plants was performed by inverting each plant into an Agrobacterium suspension such that the above ground plant tissue was submerged for 1 minute. Each inoculated T0 plant was immediately placed in a plastic tray, then covered with clear plastic dome to maintain humidity and was kept in the dark at room temperature for 18 hours to facilitate infection and transformation. Transformed (transgenic) plants were then uncovered and transferred to a greenhouse for recovery and maturation. The transgenic T0 plants were grown in the greenhouse for 3-5 weeks until siliques were brown and dry, then seeds were harvested from plants and kept at room temperature until sowing.

For generating T1 and T2 transgenic plants harboring the genes of some embodiments of the invention, seeds collected from transgenic T0 plants were surface-sterilized by exposing to chlorine fumes (6% sodium hypochlorite with 1.3% HCl) for 100 minutes. The surface-sterilized seeds were sown on culture plates containing half-strength Murashig-Skoog (Duchefa); 2% sucrose; 0.5% plant agar; 50 mg/L kanamycin; and 200 mg/L carbenicylin (Duchefa). The culture plates were incubated at 4° C. for 48 hours and then were transferred to a growth room at 25° C. for three weeks. Following incubation, the T1 plants were removed from culture plates and planted in growth mix contained in 250 ml pots. The transgenic plants were allowed to grow in a greenhouse to maturity. Seeds harvested from T1 plants were cultured and grown to maturity as T2 plants under the same conditions as used for culturing and growing the T1 plants.
