Fifty genotypes of cauliflovwer (Brassica oleracea var. botrytis) were evaluated for resistance to clubroot disease (Plasmodiophora brassicae Wor.) under controlled conditions in a plant growth chamber. The cultivars with the highest resistance were Brilant, Agora, and Bora, while the most susceptible were the cultivars White Top, White Fox, and Octavian. The variation in disease index is probably due to different pathogenicity rates of clubroot pathotypes and genetic heterogeneity of European cauliflower cultivars. The obtained results will be tested in an infested and non-infested field.

Tolerance to Pre-Harvest Sprouting in Lithuanian Winter Wheat Advanced Lines Tolerance to pre-harvest sprouting of winter wheat advanced breeding lines was evaluated at the Lithuanian Institute of Agriculture in 2005 and 2006. The tests were conducted with intact ears germinated in plastic boxes on wet filter paper in a plant growth chamber. A total of 131 breeding lines were tested during the experimental period. The experiment revealed that sprouting cumulative index (SCI) characterises resistance of lines to pre-harvest sprouting more precisely than sprouting final score (SFS). The SFS ranged from 4.3 to 9.0 in 2005 and from 5.4 to 9.0 in 2006. The SCI value was 0.14-1.0 in both years. Lines in 2005 were more susceptible to pre-harvest sprouting than those in 2006. The most resistant were found to be the lines Flair/Asketis, Torfrida/Beaver//Tarso, Širvinta1/LIA3480, while the most susceptible ones were Elena/Flair, Mermaid/Alidos, Flair/Lut.96-3 in 2005. In 2006, the most resistant lines were Pegassos/Dream, Belisar/Briz, Lars/Lut.96-3 and the most susceptible were Rostovchanka/Lut.96-3, Rector/Briz, Rostovchanka/Flair. The SFS of resistant lines was up to score 6 and the SCI value reached 0.3 in both years. The SFS of susceptible lines was 9.0 and the SCI value more than 0.9 in both years.

Sugar transporter protein (STP) genes are involved in multiple biological processes, such as plant responses to various stresses. However, systematic analysis and functional information of STP family genes in Brassica oleracea are very limited. A comprehensive analysis was carried out to identify BoSTP genes and dissect their phylogenetic relationships and to investigate the expression profiles in different organs and in response to the clubroot disease. A total of 22 BoSTP genes were identified in the B. oleracea genome and they were further classified into four clades based on the phylogenetic analysis. All the BoSTP proteins harbored the conserved sugar transporter (Sugar_tr, PF00083) domain, and the majority of them contained 12 transmembrane helices (TMHs). Rates of synonymous substitution in B. oleracea relative to Arabidopsis thaliana indicated that STP genes of B. oleracea diverged from those of A. thaliana approximately 16.3 million years ago. Expression profiles of the BoSTP genes in different organs derived from RNA-Seq data indicated that a large number of the BoSTP genes were expressed in specific organs. Additionally, the expression of BoSTP4b and BoSTP12 genes were induced in roots of the clubroot-susceptible cabbage (CS-JF1) at 28 days after inoculation with Plasmodiophora brassicae, compared with mock-inoculated plants. We speculated that the two BoSTPs might be involved in monosaccharide unloading and carbon partitioning associated with P. brassicae colonization in CS-JF1. Subcellular localization analysis indicated that the two BoSTP proteins were localized in the cell membrane. This study provides insights into the evolution and potential functions of BoSTPs.

Clubroot is a devastating disease caused by the protist Plasmodiophora brassicae Woronin. After root hair colonization, the clubroot pathogen induces clubs that block water uptake, leading to dehydration and death. The study of the severity of plant diseases is very important. It allows us to characterize the level of resistance of plant germplasm and to classify the virulence of pathogen strains or isolates. Lately, the use of learning machines and automatization has expanded to plant pathology. Fast, reliable and unbiased methods are always necessary, and with clubroot disease indexing this is not different. From this perspective, we discuss why this is the case and how we could achieve this long overdue task for clubroot disease.

Mobile users are getting smarter in using their phones. Many tasks are usually completed or monitored via a computer screen, nowadays can be taken anywhere with Android phones or tablets. Likewise with features in the phone is increasingly sophisticated. Currently bluetooth version 4 is almost mandatory in all phones. Even for entry level phones are now equipped with bluetooth version 4. This paper discusses the use of Bluetooth Low Energy—which is part of bluetooth version 4, in providing information about the status of plant growth chamber conditions. By using this concept, all phones or tablets that have bluetooth version 4 and there are applications in it will be able to receive the latest chamber status. The results show that this way of broadcasting is very effective. The data required to be monitored by a laboratory technician can be continuously broadcasted so that anyone on duty will get instant information at his grasp.
