To evaluate laboratory germin.tion.media, seed germi- n.tion.rates an. methodology for both Jatropha curcas an. Pon.amia pin.ata were coun.ed in.differen. germin.tion.medium, such as river san., quartz san. an. vermiculite. The seeds of both species were sown.at 2-cm depth of river san., quartz san. an. vermiculite. We evaluated methodologies of seeds of J. curcas an. P. pin.ata by ISTA （In.ern.- tion.l Seed Testin. Association.. The results showed that river san. is the best medium for tree seeds plan.ed at 2-cm depth of River san.. Vermiculite was secon. best. On.paper media, there were man. abn.r- mal seedlin.s an. this media were un.uitable for germin.tion.of the larger seeds.

In.er simple sequen.e repeat（ISSR） polymorphism was used to determin. gen.tic diversity an. phylogen.tic relation.hips in.90 gen.types of wild an. cultivated species of Oryza from differen. geographical region. of the world. In.all the 17 primers used in.ISSR-PCR, a total of 11 464 ban.s were amplified at 253 ban. position./loci. The primer UBC-809 amplified the maximum ban.s（1 059） at 21 ban. position.. UBC-810 an. UBC-835 amplified the min.mum of 391 ban.s each at 7 an. 14 ban. position., respectively. The mean.polymorphism in.ormation.con.en. ran.ed from 0.44 to 0.84 an. resolvin. power ran.ed from 8.69 to 23.53. Un.weighted pair group method with arithmetic mean.den.rogram an. population.structure based on.the 17 primers separated all gen.types in.o 4 major clusters with a gen.tic similarity of 53%–100%. The first two clusters con.isted of 30 O. rufipogon.accession. each. In.the third cluster, O. n.vara an. O. lon.istamin.ta grouped as on. sub-cluster an. all other O. n.vara accession. an. cultivars grouped as an.ther sub-cluster. The fourth cluster had on.y five O. rufipogon.accession. which can.be a source of n.w gen.s. Four sub-population. were iden.ified within.O. rufipogon.an. two sub-population. within.O. n.vara at K = 7. A subset of six primers with high resolvin. power values were the most in.ormative an. grouped all gen.types almost similarly as the 17 primers did. Use of these six highly in.ormative primers in.ISSR-PCR is a cost effective an. robust method for assessin. gen.tic diversity in.large germplasm collection. of wild rice species.

Arsen.c (As) an. an.imon. (Sb) are metalloids that belon. to group 15 of the periodic table an. exhibit toxic properties in.the en.iron.en.. They mostly occur n.turally at low con.en.ration. in.soil, although these can.be sign.fican.ly elevated in.both aquatic an. terrestrial food chain. as a result of dispersion.from an.hropogen.c sources, e.g ., min.n. activities. The bioavailability, i.e., the proportion.of the con.amin.n. in.soil an. dust that is available for uptake by plan.s an. other livin. organ.sms, presen.s the greatest risk to terrestrial ecosystems. Various in.vivo an. in.vitro methods have been.used to measure As an. Sb bioaccessibility in.soil an. dust. In.vivo measuremen. of bioavailability can.be time con.umin., expen.ive, an. un.thical;thus, in.vitro methods are common.y preferred. However, there is con.iderable un.ertain.y aroun. the efficacy of in.vitro tools used to measure the bioavailable fraction. of As an. Sb. The results of these methods are depen.en. on.man. variables, e.g., soil characteristics, con.amin.n. sources, an. chemical composition.of in.vitro methods. Therefore, substan.ial variation. are observed between.in.vitro an. in.vivo results obtain.d from differen. test an.mals an. en.poin.s. In.this paper, we review the literature on.As an. Sb bioavailability in.terrestrial ecosystems an. curren. in.vivo an. in.vitro techn.ques used for assessin. bioavailability an. bioaccessibility of metalloids. This would reveal research gaps an. allow scien.ists an. en.iron.en.al policy makers to gain.a deeper un.erstan.in. of the poten.ial risks associated with these metalloids in.the en.iron.en..
