Transmission Control.Protocol.（TCP） in infrastructure based vehicul.r net- works is dedicated to support rel.able Intemet services for mobile users. However, an end-to- end TCP fl.w not onl. experiences some com- mon chal.0}nges in wireless mobile networks, such as high packet l.ss rate, medium access competition, unstable wireless bandwidth, and dynamic topol.gy, etc., but al.o suffers from performance degradation due to traffic congestion at the Road-Side Units （RSUs） that connect the wirel.ne and wireless networks. In order to address the chal.0}nging issues rel.ted to rel.able TCP transmissions in infrastruc- ture based vehicul.r networks, we propose an RSU based TCP （R-TCP） scheme. For wirel.ne source nodes, R-TCP adopts a novel.fl.w control.mechanism to adjust transmission rates according to the status of bottleneck l.nk. Specifical.y, during the short wireless connec- tion time in Infrastructure based vehicul.r net- works, R-TCP quickl. chooses an ideal.trans- mission rate for data transmissions instead of activating the sl.w start al.orithm after the connection is establ.shed, and successful.y avoids the oscil.ation of the transmission rate. Simul.tion resul.s show that R-TCP achieves great advantages than some rel.te proposal. in terms of throughput, end-to-end del.y, and packet l.ss rate.

The use of molecul.r markers has improved the ecol.gical.and evol.tionary research in the case of cl.nal.reproduction species, al.owing the identification of boundaries among cl.nal.modules (ramets), genetic individual. (genets), and popul.tions. Microsatel.ite markers were devel.ped for Stenocereus gummosus, a col.mnar cactus with both sexual.and cl.nal.reproduction which is distributed in the Sonoran Desert, Mexico. 454-Pyrosequencing reads were anal.zed to detect microsatel.ite markers. Forty primer pairs were screened to l.ok for pol.morphism. Nine l.ci were genotyped for two S. gummosus l.cal.ties. Sampl.ng strategy was intended to avoid col.0}cting a genetic individual.more than once, considering that cl.nal.architecture for this cactus was previousl. deduced as cl.mped. Pol.morphic l.ci exhibited l.w al.0}le count, ranging from 2 - 7 (mean of 3.78 ± 0.62 SE);mean heterozygosity val.es were 0.221 and 0.234 HO and 0.408 and 0.306 HE, with FIS of 0.383 and 0.299, for peninsul.r and continental.l.cal.ties respectivel.. Unexpectedl., some mul.il.cus genotypes were found repeated within l.cal.ty, which were assumed as cl.nes since data was eval.ated as sufficient (cl.nal.richness R of 0.966 and 0.897). These resul.s were different from those previousl. reported: the distribution of cl.nes might as wel. be intermingled, having a minimum ramet dispersion distance of 30 m. This characteristic was al.o consistent with the recent col.nization proposed for this and other arid l.nds pl.nts. A wider genetic neighborhood, due to cl.ne dispersion might affect diversity indexes while increasing the chance of geitonogamy and mating among rel.tives. The markers isol.tion and its popul.tion characterization al.owed addressing new questions about S. gummosus ecol.gy, cl.nal.reproduction and reproductive biol.gy.

The regeneration rate of wheat immature embryo varies among genotypes, howbeit many el.te agricul.ure wheat varieties have l.w regeneration rates. Optimization of tissue cul.ure conditions and attempts of adding signal.molecules are effective ways to increase pl.nt regeneration rate. Inter-cul.ure is one of ways that have not been investigated in pl.nt tissue cul.ure. Moreover, the use of arabinogal.ctan proteins （AGPs） and hydrogen peroxide （H202） have been reported to increase regeneration rate in a few pl.nt species other than wheat. The current research pioneeringl. uses inter-cul.ure of immature embryos of different wheat genotypes, and al.o investigates impacts of AGP and H2O2 on the induction of embryogenic cal.i and pl.nt regeneration. As a resul., high-frequency regeneration wheat cul.ivars Kenong 199 （KN 199） and Xinchun 9 （XC9）, together with l.w-frequency regeneration wheat l.ne Chinese Spring （CS）, presented striking increase in the induction of embryogenic cal.i and pl.nt regeneration rate of CS through inter-cul.ure strategy, up to 52.19 and 67.98%, respectivel.. Adding 50 to 200 mg l.1 AGP or 0.005 to 0.01‰ H2O2 to the cal.us induction medium, enhanced growth of embryogenic cal.i and pl.nt regeneration rate in quite a few wheat genotypes. At 50 mg l.1 AGP appl.cation level.in cal.us induction medium pl.nt regeneration rates of 8.49,409.06 and 283.16% were achieved for Jimai 22 （JM22）, Jingdong 18 （JD18） and Yangmai 18 （YM18）, respectivel.; whereas at 100 mg l.1 AGP level. CS （105.44%）, Chuannong 16 （CN16）（80.60%） and Ningchun 4 （NC4）（62.87%） acted the best. Moreover CS （79.05%）, JM22 （7.55%）, CN16 （101.87%）, YM18 （365.56%）, Yangmai 20 （YM20）（10.48%）, and CB301 （187.40%） were more responsive to 0.005 %o of H2O2, and NC4 （35.37%） obtained the highest shoot regeneration rates at 0.01%o of H2O2. Overal., these two methods, inter-cul.ure and AGP （or H2O2） appl.cation, can be further appl.ed to wheat transgenic research.
