Solgenetics

Nathalie Kaiser closes the #SOLIOM2020 conference talking about "Assessing the contribution of Sli to self-compatibility in North American diploid potato germplasm using KASP markers". They used 5 cycles of selection on some pops. to increase the self-compatibility trait.

#SOLIOM2020 switch now to a small diploid potato inbreeding mini-session, starting with Ernst-Jan Eggers with "The S-Locus Inhibitor gene encodes an F-box protein with a Lectin domain and crucially enables hybrid potato breeding"... self-incompatibility is an important limitation

#SOLIOM2020 @ProhensJaime , presents new populations with new interesting phenotypes. One of the most interesting populations is a MAGIC population. It was develop using a 8-way funnel approach. 421 S3 lines have been phenotyped and genotyped. Old an novel QTLs have been detected

#SOLIOM2020, Yury Tikunov summarises the link between classical genetics & breeding to develop tomatoes with other flavors. The QTL analysis of a new pop revealed a QTL in chr4 associated a phenolic compounds that produce a floral aroma. Nothing new but a new gene pop up: FLORAL4

#SOLIOM2020, Yury Tikunov opens his presentation "The genetic and functional analysis of flavor in commercial tomato: a novel FLORAL4 gene underlies a QTL for floral aroma volatiles in tomato fruit" asking if someone has tasted a tomato with rose flavor? If you did, contact them.

#SOLIOM2020, Zamir: To look for epistasis in the 2000 RILs, screening trials (dry conditions) for different traits. Some regions were found for epistasis between Brix and Yield. They were able to reproduce the results in 2019 and 2020.

#SOLIOM2020, Dani Zamir: Two genetic factors to deal with #epistasis. 1) 200 individuals are not much to detect QTL-QTL interactions 2) Multiple testing penalty that need to be corrected statistically. To fix, new pop (S. pennellii x LEA or TOP) -> BC1 -> BC2 -> [S6] -> 2000 RILs

#SOLIOM2020 moves to the last session: breeding, chaired by H Tai and I Paran. Dani Zamir opens the session with "Exotic Genetic Libraries’ map resistance to Tomato Brown Rugose Fruit Virus (ToBRFV) to the Tobacco Mosaic Virus locus, TM1". He starts showing the amazing F1 hybrid

#SOLIOM2020, Golam Jalal Ahammed, closes the session with "Nitric oxide is involved in the SlWRKY81 transcription factor-regulated stomatal movement and drought tolerance in Solanum lycopersicum L."

#SOLIOM2020, Saloni Mathur continues with "Decoding the regulatory networks of diverse coding and noncoding RNAs towards heat stress response in tolerant and sensitive tomato cultivars from Indian sub-continent".

Andrea Schrader continues at the #SOLIOM2020 with "Resilience to salinity in tomato – root transcriptome data analyses" putting some salt to the session. Plant size, specially roots, are affected under salt stress. Biostimulants works on plants under salt stress, incr. roots mass

Parvinderdeep Kahlon (@ParvinderKahlon) opens the 5th session at the #SOLIOM2020 with "Population studies of the wild tomato species Solanum chilense reveal geographically structured major gene-mediated pathogen resistance". He evaluates resistance for C. fulvum on dif. pops.
