Quantification of the flavonoids in yellow lupin (Lupinus luteus; Leguminosae) seedlings revealed that a flavone glucoside, 7-O-β-(2-O-β-rhamnosyl)glucosyl-4′,5,7-trihydroxyflavone (apigenine 7-O-β-neohesperidoside), is rich in the epicotyl and cotyledon. In hypocotyls and roots, 8-C-β-glucosyl-4′,5,7-trihydroxyisoflavone (genistein 8-C-β-glucoside) was a predominant flavonoid constituent. The roles of the localized flavonoids are briefly discussed relating to defense against biotic and abiotic external stresses.

We studied the adaptation of narrow-leafed lupin (Lupinus angustifolius) and yellow lupin (L. luteus) to waterlogging because yellow lupin may have potential as a new legume crop for coarse-textured, acidic, waterlogging-prone areas in Western Australia. In a controlled environment, plants were waterlogged for 14 days at 28 or 56 days after sowing (DAS). Plants were more sensitive when waterlogged from 56 to 70 DAS than from 28 to 42 DAS, root growth was more sensitive than shoot growth, and leaf expansion was more sensitive than leaf dry weight accumulation. Waterlogging reduced the growth of narrow-leafed lupin (60–81%) more than that of yellow lupin (25–56%) and the response was more pronounced 2 weeks after waterlogging ceased than at the end of waterlogging. Waterlogging arrested net root growth in narrow-leafed lupin but not in yellow lupin, so that after 2 weeks of recovery the root dry weight of yellow lupin was the same as that of the control plants but in narrow-leafed lupin it was 62% less than the corresponding control plants. Both species produced equal amounts of hypocotyl root when waterlogged from 28 to 42 DAS but yellow lupin produced much greater amounts than narrow-leafed lupin when waterlogged from 56 to 70 DAS.

Root Death

In south-west Australia, winter grown crops such as wheat and lupin often experience transient waterlogging during periods of high rainfall. Wheat is believed to be more tolerant to waterlogging than lupins, but until now no direct comparisons have been made. The effects of waterlogging on root growth and anatomy were compared in wheat (Triticum aestivum L.), narrow-leafed lupin (Lupinus angustifolius L.) and yellow lupin (Lupinus luteus L.) using 1 m deep root observation chambers. Seven days of waterlogging stopped root growth in all species, except some nodal root development in wheat. Roots of both lupin species died back progressively from the tips while waterlogged. After draining the chambers, wheat root growth resumed in the apical region at a faster rate than well-drained plants, so that total root length was similar in waterlogged and well-drained plants at the end of the experiment. Root growth in yellow lupin resumed in the basal region, but was insufficient to compensate for root death during waterlogging. Narrow-leafed lupin roots did not recover; they continued to deteriorate. The survival and recovery of roots in response to waterlogging was related to anatomical features that influence internal oxygen deficiency and root hydraulic properties.

Lime coating yellow lupin (Lupinus luteus L.) seed, when inoculated with bacteria from agar slopes, reduced nodulation substantially. By contrast, when peat cultures were used there was no adverse effect of lime coating on nodulation, even when inoculated seeds were stored for 61 days at 75�F, before planting. In two experiments the nodulation of unhulled serradella (Omithopus comljressus L.) was generally unaffected by lime coating when either agar or peat cultures were used. In a third experiment nodulation was significantly reduced with both agar and peat cultures on unhulled and hulled seed. This adverse effect was greater with agar cultures than with peat cultures. It is concluded that peat, and possibly the serradella seed pod, protects the bacteria from the effects of lime. The practice of lime coating lupin and serradella seed, when inoculated with peat cultures, is a useful technique, particularly when the seed is sown in contact with acid superphosphate. On the other hand, some adverse effects of lime on the nodulation of serradella when a peat culture was used suggest that other workers should test the suitability of the lime pelleting method under their own conditions. Rock phosphate and bentonite were also investigated as pelleting agents, but neither seemed to offer any advantages over lime.

Aphid Tolerance

A key goal in the breeding for aphid resistance of cultivated lupins is to manipulate the levels and distributions of alkaloids. Lupin alkaloids are known to be responsible for resistance to herbivorous insects, but the total seed alkaloid level must remain under 0.02% for animal and human consumption. Yellow lupin (Lupinus luteus L.) is being investigated as a new legume crop for Western Australia (WA), but most lines produced to date have been very susceptible to aphids. In contrast, breeders in WA have had ongoing success releasing narrow-leafed lupin (L. angustifolius L.) cultivars with adequate resistance to aphids. In this study, aphid performance was evaluated on yellow lupin plants in the glasshouse from an F2 population derived from a cross between Teo, a yellow lupin cultivar resistant to aphids and with high total alkaloid levels, and Wodjil, a single plant selection from Teo that is susceptible to aphids and has low total alkaloid levels, and their parents. Resistance in Teo and the F2 progeny was strongly associated with the alkaloids gramine and a gramine analogue. The absence of plants with intermediate levels of these alkaloids in progeny of this cross makes it unlikely that aphid-resistant lines can be generated using Teo as the resistance source. On the other hand, different alkaloids were correlated with aphid resistance in the narrow-leafed lupin cultivar Kalya, and aphid resistance was more evenly distributed among progeny of a cross of the resistant cultivar Kalya with the susceptible cultivar Tallerack. For this reason, additional yellow lupin lines with a more diverse alkaloid profile were selected for further study from the Australian lupin breeding program. A wide variation in the aphid tolerance among lines was observed and aphid tolerance was positively correlated with alkaloid content. However, four lines were identified with moderate levels of aphid resistance in a low alkaloid background. These lines had varying alkaloid profiles, but as expected none were dominated by gramine and its analogues. We believe these lines offer a greater opportunity for aphid resistance breeding in yellow lupins.

Little is known about water flow across intact root cells and roots in response to hypoxia. Responses may be rapid if regulated by aquaporin activity, but only if water crosses membranes. We measured the transport properties of roots and cortical cells of three important crop species in response to hypoxia (0.05 mol O2 m–3): wheat (Triticum aestivum L.), narrow-leafed lupin (Lupinus angustifolius L.) and yellow lupin (Lupinus luteus L.). Hypoxia influenced solute transport within minutes of exposure as indicated by increases in root pressure (Pr) and decreases in turgor pressure (Pc), but these effects were only significant in lupins. Re-aeration returned Pr to original levels in yellow lupin, but in narrow-leafed lupin, Pr declined to zero or lower values without recovery even when re-aerated. Hypoxia inhibited hydraulic conductivity of root cortical cells (Lpc) in all three species, but only inhibited hydraulic conductivity of roots (Lpr) in wheat, indicating different pathways for radial water flow across lupin and wheat roots. The inhibition of Lpr of wheat depended on the length of the root, and inhibition of Lpc in the endodermis could account for the changes in Lpr. During re-aeration, aquaporin activity increased in wheat roots causing an overshoot in Lpr. The results of this study demonstrate that the roots of these species not only vary in hydraulic properties but also vary in their sensitivity to the same external O2 concentration.
