“…In Brassica plant s , a large number of studies have been carried out to investigate the mechanism of pod shattering (resistance). So far, eight pod shattering resistance related genes, including SHATTERPROOF1/2 ( SHP1/2 ) [ 12 ], FRUITFULL ( FUL ) [ 13 ], INDEHISCENT ( IND ) [ 14 ], ALCATRAZ ( ALC ) [ 15 ], NAC SECONDARY WALL THICKENING PROMOTING FACTOR 1/2 ( NST1/2 ) [ 16 ], POLYGlACTOURANAZE ( PG ) [ 17 ], REPLUMLESS ( RPL ) [ 18 ] and SPATULA ( SPT) [ 19 ] have been reported. However, the effects of pectin and PG on rapeseed pod shattering were largely unknown.…”

Rapeseed (Brassica napus L.), accounts for nearly 16% of vegetable oil, is the world’s second produced oilseed. However, pod shattering has caused significant yield loses in rapeseed production, particularly during mechanical harvesting. The GH28 genes can promote pod shattering by changing the structure of the pod cell wall in Arabidopsis. However, the role of the GH28 gene family in rapeseed was largely unknown. Therefore, a genome-wide comprehensive analysis was conducted to classify the role of GH28 gene family on rapeseed pod shattering. A total of 37 BnaGH28 genes in the rapeseed genome were identified. These BnaGH28s can be divided into five groups (Group A-E), based on phylogenetic and synteny analysis. Protein property, gene structure, conserved motif, cis-acting element, and gene expression profile of BnaGH28 genes in the same group were similar. Specially, the expression level of genes in group A-D was gradually decreased, but increased in group E with the development of silique. Among eleven higher expressed genes in group E, two BnaGH28 genes (BnaA07T0199500ZS and BnaC06T0206500ZS) were significantly regulated by IAA or GA treatment. And the significant effects of BnaA07T0199500ZS variation on pod shattering resistance were also demonstrated in present study. These results could open a new window for insight into the role of BnaGH28 genes on pod shattering resistance in rapeseed.

Background Understanding the genetic control of pod shatter resistance and its association with pod length is crucial for breeding improved pod shatter resistance and reducing pre-harvest yield losses due to extensive shattering in cultivars of Brassica species. In this study, we evaluated a doubled haploid (DH) mapping population derived from an F1 cross between two Brassica carinata parental lines Y-BcDH64 and W-BcDH76 (YWDH), originating from Ethiopia and determined genetic bases of variation in pod length and pod shatter resistance, measured as rupture energy. The YWDH population, its parental lines and 11 controls were grown across three years for genetic analysis. Results By using three quantitative trait loci (QTL) analytic approaches, we identified nine genomic regions on B02, B03, B04, B06, B07 and C01 chromosomes for rupture energy that were repeatedly detected across three growing environments. One of the QTL on chromosome B07, flanked with DArTseq markers 100,046,735 and 100,022,658, accounted for up to 27.6% of genetic variance in rupture energy. We observed no relationship between pod length and rupture energy, suggesting that pod length does not contribute to variation in pod shatter resistance. Comparative mapping identified six candidate genes; SHP1 on B6, FUL and MAN on chromosomes B07, IND and NST2 on B08, and MAN7 on C07 that mapped within 0.2 Mb from the QTL for rupture energy. Conclusion The results suggest that favourable alleles of stable QTL on B06, B07, B08 and C01 for pod shatter resistance can be incorporated into the shatter-prone B. carinata and its related species to improve final seed yield at harvest.

Carbohydrates, lipids (mostly fats and oils), proteins, vitamins, minerals, and water are the six main classes of nutrients found in foods. After carbohydrates, oils are important source of major calories required in the human diet. Oils act as a vehicle for some of the important vitamins and possess a range of nutrients and bio-active compounds. These edible oil-yielding plants can be categorized into non-woody (herbaceous) and woody (non-herbaceous) oil-bearing plants. This chapter mainly focuses on important herbaceous edible oilseed (crop)plants such as pea(ground)nut (Arachis hypogaea L.), Indian mustard (Brassica juncea L. Czern. and Coss.), rapeseed (Brassica campestris L.) (syn. B. rapa), soybean (Glycine max L.), flaxseed (Linum usitatissimum L.), sunflower (Helianthus annuus L.), sesame (Sesamum indicum L.), safflower (Carthamus tinctorius L.), and niger (Guizotia abyssinica L.). It aims to (a) overview the key insights into the origin, botany and benefits of the mentioned herbaceous edible oilseed (crop)plants; (b) highlight the major constraints for their growth and productivity (quantitative-qualitative); (c) enlighten important mitigation-approaches for minimizing the constraints-accrued impacts; (d) briefly overview the major aims and achievements of important breeding programmes focused on these oilseed-bearing (crops)plants; and also to (e) briefly present important aspects least explored on the subject.
