Figure S2: Analysis of donor parent genome introgression associated with Salinity tolerance QTL, Saltol locus using GGT version (2.0), a segment of 1.0 Mb was introgressed at the proximal end, 1.5Mb at the distal end from the donor parent genome in the best BC3F2 plant (i.e., RP6287-188-45-12-88), thus, in total, a segment of 2.5Mb was introgressed from the donor parent with respect to the genomic region in the vicinity of Saltol. The position of the polymorphic SSR markers in Mb on Chr. 1 is given in parenthesis adjacent to each marker. Figure S3: Screening for seedling stage salinity tolerance.

The data indicates no considerable difference in the relatedness among the rice lines ta the Saltol locus but a clear relatedness among the salt-tolerant lines at the OsSKC1 gene locus. The numbers on the branches indicate the distance between the rice lines (DRR Dhan58 is the line IET28784).

A new protocol for the synthesis of amides from tert-butyl peroxybenzoate (TBPB) and ammonia/amines has been developed under catalyst- and solvent-free conditions. The ammonia, primary and secondary amines reacted smoothly with TBPB to furnish the corresponding primary, secondary, and tertiary amides in excellent yields. TBPB proved to be an efficient and highly chemoselective benzoylating reagent for aliphatic amines in the presence of aromatic amines/ ­hydroxyl groups.

An environmentally benign protocol for the synthesis of quinolines in aqueous medium by using a Rh(II)acetate/TPPTS recyclable catalytic system has been developed. Anilines reacted smoothly with allyl alcohols furnishing the corresponding quinolines in moderate to good yields. This catalytic system was recycled up to five runs without much loss in its catalytic activity. Furthermore, imines were also synthesized from benzylamines in moderate to good yields.

A transition metal free base catalyzed approach for C–N bond formation via C–C and CC bond activation has been developed. The N-arylureas reacted smoothly with 1,3-dicarbonyls and α,β-unsaturated ketones to furnish the corresponding amides and imines respectively in moderate to excellent yields.

A new base-mediated protocol has been developed for the synthesis of imines and amines from N-phenylureas and alcohols under normal air. From the synthetic point of view, the protocol can be considered as an efficient alternative to conventional methods for the synthesis of imines and amines in moderate to excellent yields.

A simple, efficient, and inexpensive copper catalyzed protocol has been developed for cross-coupling of indoles with aryl halides by using glycerol as a green recyclable solvent and DMSO as an additive. The reaction was carried out at low catalyst loading furnishing various N-aryl indoles in good to excellent yield. This copper/glycerol mixture was recycled up to four runs without any loss in its catalytic activity.

An efficient methodology has been developed for the synthesis of nitriles through an aerobic oxidative reaction of alcohols and ammonium formate with copper as a homogeneous catalyst under a normal air atmosphere and solvent-free conditions. This protocol uses the air as a green oxidant and ammonium formate as the nitrogen source. A wide range of substrates were well tolerated in the reaction that gave water as a byproduct.

Various aryl amines react with either allyl alcohol or crotyl alcohol to form quinolines in efficient manner.

Application of aliphatic instead of benzylic alcohols yields carbamate and no imine derivatives, even in the absence of base.
